The BrowseName of an instance shall be “GenericSubmoduleApplication”. If uniqueness of the BrowseName is an issue, the recommended naming convention applied shall be “<NameOfStation>.<SlotNumber>.<SubslotNumber>”, where SlotNumber and SubslotNumber are obtained by reading the RealIdentificationData record.

The ApplicationTag Variable contains information determined by configuration or by applications. The Client can change the Value of this Variable by invoking the SetApplicationTag Method.

Before invoking a Method of the GsdGenSubmoduleApplicationType Object, Clients must gain exclusive write access (“lock” the GsdGenSubmoduleApplicationType Object) using the Lock Object.

This Method sets the Value of the ApplicationTag Variable. The security constraints defined in chapter 6.11 apply.

Signature

SetApplicationTag (

[in] 0:String ApplicationTag

);

Argument	Description
ApplicationTag	String containing the desired content of the ApplicationTag Variable.

The Method Result Codes (defined in Call Service) are defined in Table 19.

Table 19 – Possible Method Result Codes

Result Code	Description
Good	The Method execution was successful.
Bad_UserAccessDenied	The user has not the right to execute the Method.
Bad_InvalidArgument	The Server is not able to apply the name. The ApplicationTag string may be too long or may contain invalid characters. The server may also reject duplicates.
Bad_Locked	The GsdGenSubmoduleApplicationType Object is locked by a different Client’s Session.
Bad_RequiresLock	The GsdGenSubmoduleApplicationType Object is not locked. Clients must lock the GsdGenSubmoduleApplicationType Object before invoking a Method.
Bad_UnexpectedError	The server is not able to execute the function because an unexpected error occurred. The Device might be temporarily unavailable or unreachable due to network failure.

The Lock Object ensures exclusive Method call for one Client. The Client locks the GsdGenSubmoduleApplicationType Object by invoking the InitLock Method of the Lock Object. The Client invokes ExitLock to release the lock.

The CommunicationStatus Property reports the communication status of the Submodule encoded as GsdGenIoCommunicationStatusEnumeration. If the Submodule is performing cyclic data transfer with a Controller, the Value shall be INDATA (ConfigurationStatus Property is either OK or SUBSTITUTE). If not (ConfigurationStatus Property contains WRONG) or if the Submodule is not configured (see 6.1), the Value shall be OFFLINE.

The ConfigurationStatus Property reports the configuration status of the Submodule indicated by the SubmoduleState.IdentInfo block encoded as GsdGenIoConfigurationStatusEnumeration. If the CommunicationStatus Property contains INDATA, possible Values are OK or SUBSTITUTE. If the CommunicationStatus Property contains OFFLINE (see above) for configured Submodules, the Value shall be WRONG. If the Submodule is not configured, the Value shall be UNKNOWN (see 6.1).

The optional ARIdentifier Property contains the ARUUID returned by the ARData record encoded as 0:Guid DataType. The Property shall only be provided if the CommunicationStatus Property contains INDATA. Intended to be used to give additional information about the AR to which the Submodule belongs, if the PROFINET aspect (part 30140) is not provided.

The optional ControllerName Property contains the NameOfStation of the Controller which owns and controls the Submodule. Intended to be used to show the related Controller/PLC if the PROFINET aspect (part 30140) is not provided.

The Input Object contains the Objects and Variables representing the Submodules Input Data. See 6.3 and 6.4 for details.

The Output Object contains the Objects and Variables representing the Submodules Output Data. See 6.3 and 6.4 for details.

The Configuration Object is an optional folder containing GsdGenParameterVariableType Variables representing the configuration Parameters of the Submodule. See section 6.6 for details.

The <ValueVariable> Variable represents one Data Object modelled as Variable as described in 6.7. There shall be as many 0:BaseDataVariableType Variables as are needed to represent the Data Objects which shall be represented as Variables. The BrowseName is either the GSDML Name (see Table 64) or the BMP Name (see Table 65) for BMPs. Data Objects with engineering unit shall always be represented by a Variable.

Numeric Data Objects with specified engineering unit shall be represented by 0:AnalogUnitType Variables, numeric Data Objects with specified engineering unit and range information shall be represented by 0:AnalogUnitRangeVariable Variables (<UnitVariable> and <UnitRangeVariable> placeholders). The BrowseName is either the GSDML Name (see Table 64) or the BMP Name (see Table 65) for BMPs.

The EngineeringUnit Property of the 0:AnalogUnitType and 0:AnalogUnitRangeType Variables shall contain the mapped UNECE code of the OPC UA EUInformation data type (see [OPC 10000-8], 5.6.3) for the engineering unit of this Data Object. The engineering unit is either determined by the GSDML Unit (see Table 64) or by the BMP Unit (see Table 65) for BMPs.

The EURange Property of the 0:AnalogUnitRangeType Variable shall be provided for Data Objects with associated engineering unit. The Value is determined by the GSDML Range (see Table 64) or by the BMP Range (see Table 65).

The <ValueProperty> Property represents one Data Object modelled as Property as described in section 6.7. There shall be as many 0:BaseDataType Properties as are needed to represent the Data Objects which are specified to be represented as Properties. Vendors shall not specify a representation as Property if an engineering unit is specified for the data value. BMPs shall not be represented as Properties.

The DataType of the Variables and Properties representing Data Objects is determined by the GSDML Type (see Table 64) or by the BMP Type (see Table 65) for BMPs. The ValueRank of a Data Object Variable or Property can be either a scalar or a single-dimensional array. If a conversion factor and an offset are to be applied for the display value (See C.1, “opc:Offset” and “opc:Gradient” attributes of “Meta” element, and [PDP], 6.2.1.3, Standardisation factor and Variable attribute), the DataType shall be 0:Float or 0:Double.

The <EnumerationVariable> represents one BMP “simple variable” (see [PDP], 6.2.1.4) with a text array assigned to an unsigned 8/16/32 or Boolean value (Bit 10 of the parameter description element “Identifier (ID)” is set to 1). The parameter value serves as index into the text array, see 6.7.1 also. The Server shall create a 0:Enumeration DataType and assign each text element of the text array to the description member of the 0:EnumValueType element structure of the EnumValues Property with the same index. Table 20 shows the assignment of parameter value, array index and text array elements.

Table 20 – EnumValues member assignment

EnumValues[Index]	Assigned value
value	Index == value of parameter
displayName	<Index>_<BMP Name >
description	Text array[Index]

The BrowseName of the generated 0:Enumeration DataType shall be created according to following template string: GsdGen <BMP Name >EnumerationType.

The BMP shall be represented as 0:Enumeration if the “RefMeta” element describing the BMP has a “Meta” child element with the “Property” attribute “opc:DestinationDataType” and the “Content” attribute “Enumeration” (see Table 63).

The <OptionSetVariable> Variable represents one BMP “simple variable” with a text array assigned to a “V2” data value (see [PDP], 6.2.1.4). The Server shall obtain the current value of the BMP and set the Boolean values in the BitMask array Property, starting with Bit 0 (LSB) of the sequence for the array element with index 0. The corresponding OptionSetValues array elements shall be set with the text string element from the assigned text array. Since two strings are assigned for the possible two states of each Bit in the sequence, the Server shall insert the text valid for the actual state of the Bit. For details of the assignment of elements of the text array to the actual value of the described Bit see [PDP], 6.2.1.4.

The BMP shall be represented as 0:OptionSetType if the “RefMeta” element describing the BMP has a “Meta” child element with the “Property” attribute “opc:DestinationDataType” and the “Content” attribute “OptionSetVariable” (see Table 63).

The <ArrayFolder> component Reference points to 2:FunctionalGroupType folder Object created as root Object to represent an array BMP as described in chapter 6.7.1.

The BMP shall be represented as folder Object if the “RefMeta” element describing the BMP has a “Meta” child element with the “Property” attribute “opc:DestinationDataType” and the “Content” attribute “ArrayFolder” (see Table 63).

The <FolderName> optional component Reference points to 2:FunctionalGroupType folder Object created according to the description in section 6.9.

The GsdGenSubmoduleApplicationType Object shall relate to the Submodule Object it represents in the PROFINET aspect with a 0:RepresentsSameFunctionalityAs ReferenceType as shown in Figure 6.

The Server might provide diagnosis data by sending GsdGenAlarmEventType Events.

The components of the GsdGenSubmoduleApplicationType representing one Data Object have additional subcomponents which are defined in Table 21.
