7.2 OPC UA for RIO Channel Types

There are different RIO Channel types defined for each profile for digital and analog Input as well as for digital and analog Output. Table 29 lists the RIO Channel types defined in this specification for the Common Application Profiles RIOforPA and RIOforFA. All RIO Channel types are subtypes of the RioChannelType defined in chapter 7.2.1.

Table 29 – RIO Channel Types

Profile	Input Channels
	Digital	Analog
RIOforPA	RioPaDigitalInputChannelType	RioPaAnalogInputChannelType
RIOforFA	RioFaDigitalInputChannelType	RioFaAnalogInputChannelType

	Output Channels
	Digital	Analog
RIOforPA	RioPaDigitalOutputChannelType	RioPaAnalogOutputChannelType
RIOforFA	RioFaDigitalOutputChannelType	RioFaAnalogOutputChannelType

7.2.1 RioChannelType

The RioChannelType is the base type for all RIO-channel types. The type shall not be used directly. Instead, only the subtypes shall be instantiated.

The RioChannelNumber Property shall contain a unique channel number. Uniqueness shall be guaranteed for all RIO Channel Objects aggregated by a RIO Channel Group. The value range used for the RioChannelNumber Property Values shall be continuous and start with 0.

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

7.2.1.1 SetApplicationTag Method

This Method sets the Value of the ApplicationTag Variable. The security constraints defined in chapter 6.7 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 31.

Table 31 – 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_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 Server might provide diagnosis data by sending RioChannelDiagnosisEventType Events and / or RioChannelDiagnosisAlarmType Events. The diagnosis data of the RioChannelGroup Object includes the diagnosis information of all aggregated RIO Channel Objects.

If the SetApplicationTag Method is invoked or if parameterization data provided by the subordinated RioChannelGroupConfigType Object is changed, the value of the LastParameterChange timestamp Variable shall be changed by the Server. This includes the EngineeringUnits and EURange Properties of Process Value Variables and any change of configuration data provided by the “Config” Objects.

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

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

The ProcessValue Variable contains a Controller’s output data to an automated process.

The ProcessValueReadback Variable contains the readback value obtained by reading the output signal back through the Transducer and the Function Block.

The SignalValue Variable contains the output signal value fed to the signal coupling in the Transducer.

The SignalValueReadback Variable contains the output signal read back through the signal coupling in the Transducer.

The Config Variable contains the configuration properties available for the RIO Channel. See the definition of the RioFaDigitalOutputConfigVariableType (see chapter 9.4.4)
