Format of the CSV Data

In order to create instances of S7 PLUS devices, you must create the engineering data in the form of a comma-separated value (CSV) file. A CSV file contains data in which values are represented as text and separated using a separator such as comma (,). The file in the CSV format can be edited in text editors such as Wordpad or Notepad. More elaborate editing can be done using advanced word processing tools, like Excel. A CSV file is divided into the following sections.

Header

The Header section contains two separators, a List Separator and a Decimal Separator. Both these separators are placed in the same sequence on two subsequent lines. These separators are placed inside quotes for easy identification.

The List Separator is used as a delimiter for parsing of row data in the CSV file.

The Decimal Separator is used for parsing of fields having values as floating point numbers.

Driver

Specifies the name of the subsystem (For example, S7 PLUS) to which the CSV file is associated with.

FileVersion

Displays the current version of the CSV file.

Texts

Allows you to add a new text group to the system.

Hierarchy

Allows you to specify the classification attributes (Discipline, Subdiscipline, Type, Subtype, and Function) to the objects in the Logical and User hierarchy levels.

Smoothing

Allows you to specify the smoothing configurations.

Item	Description
SmoothingConfigName	Name of a specific smoothing configuration
SmoothingType	Specifies when the value of a point is to be recorded on the management station. The smoothing types vary according to the datatypes. It is applicable only for points of type INPUT. The possible values for Smoothing Type are: value - Value of a point is recorded on the management station only after it crosses the percentage or absolute limit set for the point in deadband. For example, an integer point has a present value of 100 and a deadband of 5%. As per the concept of value smoothing, the value of the point is recorded on the management station only after the point value exceeds 105 or falls below 95. time - Value of a point is recorded on the management station only after exceeding the tolerance time specified in the [Seconds] and [Milliseconds] fields in the CSV. For example, if the time limt is set to 10 seconds, then the change in the value of the point will be recorded on the management station only on completion of 10 seconds. oldnew - Value of a point is updated on the management station only when there is a change in the value of the point on the device. valueandtime - Value of a point is recorded on the management station only after it crosses the percentage or absolute limit set for the point in deadband and after it exceeds the tolerance time specified in the [Seconds] and [Milliseconds] fields in the CSV. For example, an integer point with 100 as present value, 5% as deadband, and 10 seconds as the tolerance time, will pass smoothing only when its value exceeds 105 or drops below 95 and after completion of the tolerance time of 10 seconds. valueortime - Value of a point is recorded on the management station after it crosses the percentage or absolute limit set for the point in deadband or after it exceeds the tolerance time specified in the [Seconds] and [Milliseconds] fields in the CSV. For example, an integer point with 100 as present value, 5% as deadband, and 10 seconds as the tolerance time, will pass smoothing either when its value exceeds 105 or drops below 95 or completes the tolerance time of 10 seconds. oldnewandtime - Value of a point is recorded on the management station only when there is a change in the value of the point on the device and it exceeds the tolerance time specified in the [Seconds] and [Milliseconds] fields in the CSV. For example, an integer point with 100 as present value and 10 seconds as the tolerance time, will pass smoothing only when there is a change in the value of the point on the device and after completion of the tolerance time of 10 seconds. oldnewortime - Value of a point is recorded on the management station only when there is a change in the value of the point on the device or it exceeds the tolerance time specified in the [Seconds] and [Milliseconds] fields in the CSV. For example, an integer point with 100 as present value and 10 seconds as the tolerance time, will pass smoothing only when there is a change in the value of the point on the device or after completion of the tolerance time of 10 seconds.
Deadband	The tolerance range specified in Absolute or Relative terms.
IsRelative	Allows you to specify if an absolute or relative value is to be specified for the deadband. TRUE or 1: The value of deadband will be in percentage (%) with respect to the present value of the point. FALSE or 0: The value of deadband will be absolute. In such cases the unit of the respective point will be assigned.
Seconds	Tolerance time in seconds
Milliseconds	Tolerance time in milliseconds

Item	Description
Table Name	Name of the text group.
Index	An integer value representing the different states of the text group.
Text	Text associated with each integer value of the text group.

PollGroups

Allows you to import poll groups to the system. If you have created a pollgroup for Pooling, then it can be assigned only to points that have the PollType set to Pooling or Pooling on Demand, it cannot be set for points that have COV as the PollType.

Item	Description
Poll Group Name	Name of the poll group to be imported in the system. The name of the poll group must start with PollGr.
Interval	Time interval for the poll group.

Important Points to consider for Poll Group Import

Poll groups are applicable only to the points where the Direction field is set to Input and INOUT.
If the [POLLGROUPS] section is available in the CSV file but there are no poll groups assigned to the points, all poll groups listed in the [POLLGROUPS] section will be imported into the system. After import, they will be added to the following location, Project > Management System > Servers > Main Server > Poll Groups.
If the poll groups assigned to the points are listed in the [POLLGROUPS] section, the poll groups will be added to Project > Management System > Servers > Main Server > Poll Groups and assigned to the respective points after the import of the CSV file.
A pollgroup listed in Project > Management System > Servers > Main Server > Poll Groups, but not listed in the [POLLGROUPS] section in the CSV file is associated with a point in the CSV file, then the pollgroup is assigned to the point after import. If the poll group is neither available in the Poll Groups folder nor listed in the [POLLGROUPS] section, an error message will be issued on parsing the CSV file.
If a data point with input direction does not have a poll group assigned or the assigned poll group is not available in the CSV file or in the Project > Management System > Servers > Main Server > Poll Groups node, the poll group specification is taken from the network node during the import of the CSV file.
Imported poll groups are present at the following location in the System Browser, Management System > Servers > Main Server > Poll Groups.

PollGroups_COV

Allows you to import poll groups to the system. You can associate poll groups of type COV only to those points that have the polltype as COV. If a pollgroup is created for COV, then it cannot be used for points that have polltype set to Polling on Demand or Polling.

Item	Description
Poll Group Name	Name of the poll group to be imported in the system. The name of the poll group must start with PollGr.
Interval	Time interval for the poll group.
Unsubscribe	Enables switching of poll groups that can only be associated with PollType COV to Polling or Polling on Demand. The value of Unsubscribe can be either of the following: TRUE or 1 – Convert the pollgroup to support Polling or Polling on Demand. FALSE or 0 - Retain the pollgroup to support only COV polltype. NOTE: Switching of poll groups from COV to Polling or Polling on Demand or vice versa might cause inconsistencies in the system.

FALSE or 0 – Turns OFF the VL flag for the point on importing the CSV. NOTE: If no value is specified in this field, then the current state of the point will be retained on re-importing the CSV file.
Smoothing	Name of the smoothing configuration to be associated with the point. This value is specified from the [SMOOTHING] section.
AlarmClass	Generic Alarm class. Defines the Alarm Class to be enabled for an event (for example, Alarm, Anomaly, Blocked$Fault,) For multiple alarms or alarm classes, separate the alarm class by the $ characters. Syntax: [AlarmClass]=<AlarmClass1>$<AlarmClass2>$ <AlarmClass3>… Example Alarm$Fault$Anomaly

AlarmValue	Defines the value for which an alarm is reported. The range is indicated by the $ character. For example, if the Alarm Value is 40$50, it means that alarm values are between 40 and 50. Syntax: [AlarmValues]=<AlarmValue1>$<AlarmValue2>$ <AlarmValue3>… The syntax of Between (-BET) and Not Between (-NBET) operators are as follows: [Value1$Value2] For multiple alarms containing both Equals and Range alarms, the syntax should be like this: “10$[40$50]” NOTE: If the StateText field is defined, then the AlarmValue field will use it. The point will be imported without alarming if this field is not present.
EventText	Alarm text for incoming event. For multiple alarms, multiple event texts can be defined. Syntax: [EventText]=<EventTexts1>$<EventText2>$ <EventText3>… Examples: "Error", "Error$Warning", "Error$Warning$DangerLevel” …

UpperHysteresis	Defines the upper range for the alarm value; beyond which alarms will be generated. For example, if the alarm set for the value is greater than 50 and the UpperHysteresis is set to 2, then the alarm is only generated when the alarm value reaches 52.
LowerHysteresis	Defines the lower range for the alarm value below which alarms will be generated. This value is always specified as a negative. For example, if the alarm set for the value is less than 50 and the LowerHysterisis is set to -2, then the alarm is only generated when the alarm value falls to less than 48.
NoAlarmOn	Defines whether or not an alarm is triggered whenever the connection to the device is lost. This field can have either of the following values: None or Blank: If None is specified or if no value is specified in this field, then on importing the CSV file, the No alarm on driver invalid check box in Alarm Configuration section of the Object Configurator is not selected. In this case, if alarm is configured on default value then that alarm will be raised whenever the connection to the device is lost. DriverFail: If the value specified is DriverFail, then on importing the CSV file, the No alarm on driver invalid value will be selected in the Alarm Flags drop down list in the Alarm Configuration section of the Object Configurator. In this case, if alarm is configured on default value then that alarm will not be raised even if the connection to the device is lost. SourceTimeInvalid: If the value specified is SourceTimeInvalid, then on importing the CSV file, the No alarm on SourceTimeInvalid value in the Alarm Flags drop down list is selected in the Alarm Configuration section of the Object Configurator. In this case, if alarm is configured then that alarm will not be raised if the timestamp of that value is invalid.
LogicalHierarchy	Logical Hierarchy of the data point in the logical view. The logical hierarchy path in the CSV file must start with a backslash (\). Syntax:[Delimiter]<Level1>[Delimiter]<Level2> [Delimiter]…[Delimiter]<Level-n>[Delimiter]<(Optional) Name Of the datapoint> For example, \BuildingA\Floor3\Room403\Sensor1 The last entry after the backslash (\) represents the name of the datapoint in the logical view. This entry is not mandatory. If the name of the datapoint is not specified in the Logical Hierarchy field, then on import, the name of the datapoint as specified in the Name field displays in the logical hierarchy path of the System Browser. For example, a datapoint with name Light403_11 in the Name field has the following value in the Logical Hierachy field, \BuildingA\Floor3\Room403\. On importing the CSV file, the logical hierarchy path as displayed in the System Browser will be, <Logical Hierarchy Root Node>\BuildingA\Floor3\Room403\Light403_11. This is because in the Logical Hierarchy field, the name of the datapoint is not specified. However, if we change the path in the Logical Hierarchy field to, \BuildingA\Floor3\Room403\Light403, then on importing the CSV file, the logical hierarchy path as displayed in the system browser will be, <Logical Hierarchy Root Node>\BuildingA\Floor3\Room403\Light403. This is because in the Logical Hierarchy field, the name of the datapoint is specified as Light403.
UserHierarchy	User Hierarchy of the data point in the user view. The user hierarchy path in the CSV file must start with a backslash (\). Syntax:[Delimiter]<Level1>[Delimiter]<Level2> [Delimiter]…[Delimiter]<Level-n>[Delimiter]<(Optional) Name Of the datapoint> For example, \BuildingA\Floor3\Room403\Sensor1 The last entry after the backslash (\) represents the name of the datapoint in the user view. This entry is not mandatory. If the name of the datapoint is not specified in the UserHierarchy field, then on import, the name of the datapoint as specified in the Name field displays in the user hierarchy path of the System Browser. For example, a datapoint with name Light403_11 in the Name field has the following value in the UserHierarchy field, \BuildingA\Floor3\Room403\. On importing the CSV file, the user hierarchy path as displayed in the System Browser will be, <User Hierarchy Root Node>\BuildingA\Floor3\Room403\Light403_11. This is because in the UserHierarchy field, the name of the datapoint is not specified. However, if we change the path in the UserHierarchy field to, \BuildingA\Floor3\Room403\Light403, then on importing the CSV file, the user hierarchy path as displayed in the system browser will be, <User Hierarchy Root Node>\BuildingA\Floor3\Room403\Light403. This is because in the UserHierarchy field, the name of the datapoint is specified as Light403.

¹⁾	Mandatory field

N to 1 Mapping

The concept of N to 1 mapping is used in situations in which you want to assign the address to specific properties of an object. The properties to which the address is to be assigned are specified in the [Property] field next to [Object Model] in the [POINTS] section of the CSV.

In this example, we will assign the address to Property 1, Property 2, and Property 3 of the CustomOM_1 object model.

Value Assignment

Allows you to assign a value to the Semantic_Tag or any propertyof type String to any S7 PLUS device or point. The property must be present in the object model of the device or point. You can also assign the Semantic_Tag property to any device or point that is present in the system or in the CSV file.

After importing the CSV file the Semantic_Tag property is assigned to the S7Plus_Device_1 device and CustomPoint3. The property and it’s value displays in the Extended Operation tab if those properties are configured to display in Extended Operation tab.

Import Rules for S7 PLUS Devices

Import Rules allow you to configure the rules for importing the object definitions for the objects of a particular S7 PLUS family. You can configure the import rules from the Import Rules folder in the S7 PLUS library. Before proceeding with the configuration, you must ensure that the S7 PLUS library is customized to the headquarter level as the importer reads and sets the rules from the headquarter level only.

Each Import Rules library element contains the rules for a specific product family (such as S7 PLUS and so on).

Using Import Rules, you can define the objects and properties for the import rules using the Objects and Properties expander. You can create another object with Copy Object and delete an object with Remove Object.

Modifying the Import Rules
Modifying the Import Rules may seriously affect the system's behavior and should always be done by a qualified system librarian. Do not modify any of such rules unless you know exactly what you are doing.

Objects and Properties Expander

The Objects and Properties expander allows you to change the configuration of existing objects, create new entries, or removed unwanted object entries.

Objects and Properties Expander Fields
	Description
DataType	Displays the S7 PLUS types (objects) contained in the S7 PLUS CSV file.
Direction	Displays the directions of the object, Input, Output, or InputOutput.
Transformation Type	Displays the transformation types.
Object Model	For each S7 PLUS object type, you can select or edit a specific object model.
Add Object	Adds a new import rules entry to the table.
Copy Object	Copy the selected object to the table.
Remove Object	Remove the selected object from the table.

Parsing Information in the CSV File

The csv file is parsed for errors and inconsistencies by the importer during the import process. The Importer can only parse CSV files which use a comma (,) as a separator. The CSV file contains mandatory, as well as non-mandatory data.

The following table provides more information related to the parsing of data with reference to mandatory and non-mandatory information in the CSV file.

Error Condition	Result
Value of a mandatory field is incorrect in a CSV file row	The data in the entire row is not allowed for import. The information is logged as an error message in the Analysis Log and Trace Viewer.
Value of a mandatory field is blank in a CSV file row	The data in the entire row is not allowed for import. Information is logged as as error message in the Analysis Log and Trace Viewer.
Value of a non mandatory field is incorrect in a CSV file row	The value of that particular field is not allowed for import. However, the other values in the row are imported. Information is logged as a warning message in the Analysis Log and Trace Viewer.
Value of a non mandatory field is blank in a CSV file row	The entire row is imported. This information is logged as a warning message in the Analysis Log and Trace Viewer.

The Importer parses the CSV file row by row and imports the data in that row if it does not have any of the above mentioned error conditions. On successful import, the objects are created below the S7 PLUS network node in the System Browser.

Validations for Parsing the CSV File Entries for Devices

If the given device name contains invalid characters, then it is treated as invalid.
If the given device name contains special characters other than underscore( _ ), then it is treated as invalid.
If the given device name ends with (_2), then it is ignored. Device names ending with (_2) are reserved by WinCC OA for project redundancy.
If the given device name already exists in the same CSV file, then the new entry is treated as invalid.
If an ObjectModel that is mentioned in the CSV file does not exist in the system, then it is treated as invalid.
If the CSV file contains only device entries and the other sections are not present, then those entries are ignored.
If a point entry is present above the device entry, then the point entry is ignored. A point is always present below the device entry.
If there are any point entries present without the parent entry of the device, then those point entries are ignored.
There can be multiple point entries under a device entry in the CSV file.

Activity and Online Trend Logging

You can configure the activity and online trend logging for a point by specifying either of the following values in the CSV file:

TRUE or 1
FALSE or 0

If no value is specified in this field, then the current state of the point will be retained on re-importing the CSV file.

After importing the CSV file, the Properties expander will reflect the following values:

Min, Max, Unit, Resolution

The Min, Max, Resolution, Unit data in the CSV can be configured as follows:

The Min, Max, and Unit fields can be set for values of type INT, UINT, REAL.

The Resolution field can be set only for values of type REAL.

After importing the CSV file, the Details expander reflects the changes.

S7 PLUS DataTypes

S7 Data Type	Range
S7 Data Type	Min	Max
S5TIME	0H_0M_0S	2H_46M_30S
TIME	-24D_20H_31M_23S	24D_20H_31M_23S
TIME OF DAY	0:0:0	23:59:59

For other datatypes, the values for Min and Max are defined as configured in the object model.

Scaling Factor

The Min Raw, Max Raw, Min Eng, and Max Eng data in the CSV can be configured as follows:

These values are allowed only for data of type INT, UINT and FLOAT. You can also assign negative values to these fields. However, the values should not be equal.

After importing the CSV file, the Value Conversion expander reflects the changes.

Alarming

To configure a workstation alarm for a point, you must configure the following fields:

AlarmClass: The alarm class to be enabled for an event.
AlarmType: The condition for issuing an alarm. Refer to the table below.
AlarmValue: The value, or range of values, for which an alarm is to be issued.
EventText: The text to display when the alarm is issued.
NormalText: The text to display when the alarm ceases.
UpperHysteresis: The upper range for the alarm value; beyond which alarms will be generated.
LowerHysteresis: The lower range for the alarm value; below which alarms will be generated.

Alarm Type Operators and Their Meanings
AlarmType Operators	Operand	Meaning	Applicable Alarm Category
OR	=	Equal to (only for binary points)	Discrete
EQ	\|\|	OR
NE	!\|\|	NOR
BET	..	In the range of two values
NBET	!..	Not in the range of the two values
LT	<	Less than	Continuous
LE	<=	Less than or equal to
GT	>	Greater than
GE	>=	Greater than or equal to

Error Conditions for Workstation Alarms

Supported alarm type values are: EQ (equal), NE (not equal), LT (less than), LE (less than or equal), GT (greater than), GE (greater than or equal), BET (between), NBET (not between).
EQ (equal to) is the only supported alarm type value for binary (Boolean) points.
Only one alarm can be specified for binary (Boolean) points.
Alarm configuration is ignored if discrete and continuous alarms are mixed. Refer to the table for categorization of alarm types.
Alarm configuration is ignored if the number of alarm values and range is inconsistent in the alarm configuration columns.
Alarm types BET and NBET are not supported for items with state texts.

The following examples illustrate single and multiple alarm configurations.

Alarm Configuration for a Single Alarm

The CSV configuration for a single alarm is as follows.

After importing the above CSV, the alarm will be configured as follows.

Alarm Configuration for Multiple Alarms

The CSV configuration for multiple alarm is as follows.

After the import of the above CSV, the alarm configuration looks like this.

State Texts for Enumerated and Boolean Types

Enumerated and Boolean data types usually require specific texts to be displayed instead of raw values. For example, the 0 / 1 of Boolean type must be represented as Start/Stop. This is achieved by specifying the texts in the StateText field. The discrete state texts are separated by the $ character.

The StateText attribute in a CSV for a Boolean point can be configured as follows:

Since a Boolean point can have a maximum of two states, the text group also has two states. These two states correspond to the two value range of Minimum and Maximum. After the CSV import, the Details expander displays as follows:

To represent more than two states, you must configure the StateText attribute of a multi state point. In the CSV file example shown below, the text group has three states’ State1, State2, and State3.

After the CSV import, the Details expander displays as follows:

Now, from the drop down list, you can select the state from the list of states. Selecting a state will write the corresponding value to the point. The range of this value is between the minimum and maximum specified in the CSV file.

After importing the CSV for such a point, its text group is also added to the list of text groups. The following image displays the Text Group Editor showing the three state texts.

The Importer verifies the text group names either from the text groups defined in the Text section in the same CSV file, or from the text groups present in the system.

StateTexts are applicable only for Multistate and Binary points since floating point values do not have integral states. However, the Importer ignores the StateText data for all other datatypes.

During re-import, the Importer replaces an existing text group of the point with the new text group mentioned in the CSV file.

Dependency of StateTexts on the Minimum and Maximum Values of a Point

During the parsing of a CSV file, the StateTexts are verified with the minimum and maximum values given in the CSV file. The Importer can fail in parsing StateTexts due to the following reasons:

The minimum and maximum values are invalid (for example, format error, non-integral values).
The interval between the minimum and the maximum value is not equal to the number of StateTexts provided in the entry.
The minimum is equal to maximum.

In such cases, a warning message is added to the Preimport log file. However, the parsing continues ignoring the StateText values of such a point.

Function Mapping

If all the classification attributes (Discipline, Subdiscipline, Type, Subtype, Functions) are defined in the CSV file, then on importing the CSV file, the proper classification attributes are assigned to the S7 Plus Devices and Points.
