PROFI-RemoteIO - 6.8 Process Value Qualifier and StatusCode Relationship

6.8 Process Value Qualifier and StatusCode Relationship

When returning the Value of Process Values, the Server shall set the StatusCode member of the DataValue structures returned by the Read Service and the Publish Service consistent with the Process Value Qualifier information defined for Process Value Variables and structures.

6.8.1 Process Value Qualifier and StatusCode Relationship for RIOforPA

RIOforPA status information is conveyed to the Client as copy of the original status transmitted in the telegram signal. The value of the RioPaProcessValueQualifierVariableType Variable and the Qualifier member of the RioPaAnalogValueDataType and the RioPaDigitalValueDataType shall contain the original status. In addition to this, the status can be encoded into additional qualifier values encoded as RioQualityEnumeration, RioSpecifierEnumeration and RioQualifierEnumeration enumeration values.

6.8.1.1 Condensed Status restricted to NE 107

If the Device generates condensed status codes restricted to NE 107 (See [PCD] chapter 5.4.3.2), the status information delivered for one Process Value and the OPC UA StatusCode shall be set consistent as defined in Table 13.

Table 13 – Condensed status restricted to NE 107

NE 107	Status Byte Values	Description according to Profile		OPC UA Status Code	RioQualityEnumeration	RioSpecifierEnumeration	RioQualifierEnumeration
Failure (F)	0x24,0x26		BAD - maintenance alarm, more diagnosis available	Bad, 0x80000000	BAD	FAILURE	BAD_MAINTENANCE_ALARM

	0x79, 0x7B						UNCERTAIN_NO_MAINTENANCE_SIMULATION_ACTIVE

	0xA8, 0xAA		GOOD - maintenance demanded	Good, 0x00000000	GOOD	MAINTENANCE_REQUEST	GOOD_MAINTENANCE_DEMANDED
	0xA9, 0xAB						GOOD_MAINTENANCE_DEMANDED_SIMULATION_ACTIVE
Good (G)	0x80		GOOD - ok	Good, 0x00000000	GOOD	NORMAL	GOOD
Check (C)	0x81		GOOD - simulation active	GoodEdited, 0x00DC0000	GOOD	FUNCTION_CHECK	GOOD_SIMULATION_ACTIVE
Good (G)	0x82		GOOD - update event	Good, 0x00000000	GOOD	NORMAL	UPDATE

The two values for status bytes consider the possible appearance of the update bit as defined in [PCD]. The update bit is not mapped further into separate status values. In contrast, the appearance of the “simulation active” bit is mapped to special values of the RioQualifierEnumeration.

6.8.1.2 Status with detailed Information

If the Server generates status codes with detailed information (See [PCD] chapter 5.4.3.3), the status information delivered for one Process Value and the OPC UA StatusCode shall be set consistent as defined in Table 14.

According to [PCD PB] chapter 5.3.4.2.1, the classic status codes shall be supported for legacy Devices requiring backward compatibility only. Otherwise, only condensed status generation or condensed status with detailed information as defined in 6.8.1.1 and 6.8.1.2 is required.

6.8.2 Process Value Qualifier and StatusCode Relationship for RIOforFA

RIOforFA status information is conveyed to the Client as copy of the original status transmitted in the telegram signal. The value of the RioFaProcessValueQualifierVariableType Variable and the Qualifier member of the RioFaAnalogValueDataType and the RioFaDigitalValueDataType shall contain the original status. In addition to this, the status can be encoded into additional qualifier values encoded as RioQualityEnumeration.

The status information delivered for one Process Value and the OPC UA StatusCode shall be set consistent as defined in Table 16.

Table 16 – RIOforFA StatusCodes

Status Bit Value	Description according to Profile (See [RIO FA] chapter 7.1)	OPC UA Status Code	RioQualityEnumeration
1 (good)	Input: Process Value can be used by host application. Output: Physical signal equals Process Value.	Good, 0x00000000	GOOD
0 (bad)	Input: Process Value should not be used by host application. Output: Substitute Value applied by (Sub)Module.	Bad, 0x80000000	BAD

6.8.3 StatusCode of Arrays of Process Values

When returning arrays of Process Values, the Server shall set the Severity of the StatusCode to “Bad” if one or more Process Values in the returned array are “Bad”. If no Process Value in the array is “Bad”, the Severity returned shall be “Uncertain” if one or more Process Values in the returned array are “Uncertain”. The Severity returned shall be “Good” only if all Process Values in the array are “Good”.
