Output Description

Function block HA_CS31_DIAG_EXTD_VIA_CM574

DONE

Data_Type	Default_Value	Range	Unit
BOOL	-	TRUE / FALSE	-

Output DONE indicates the state of execution.

It has the value TRUE when the execution is finished and the outputs are valid. When DONE becomes FALSE other outputs are not valid any more.

ERR

Data_Type	Default_Value	Range	Unit
BOOL	-	TRUE / FALSE	-

Output ERR indicates whether an error occurred during Function Block execution.

It is only valid when DONE is TRUE. The kind of occurred error is specified by the error identifier at output ERNO.

ERNO

Data_Type	Default_Value	Range	Unit
WORD	-	0 … 65535	-

At output ERNO the identifier of an occurred error is provided. It is only valid when DONE and ERR is TRUE. (see, error messages): Error Messages of the Function Block Libraries

BOOL_OUT_EQ (BOOL out equal)

Data type: DWORD.

Each bit of the DWORD represents identical output buffer for BOOL data in each CS31 slave.

BOOL_OUT_DIFF (BOOL out difference)

Data type: DWORD.

If PLC A and PLC B bool output buffer is different, then this bit will turn on to TRUE.

ANALOG_OUT_EQ (analog out equal)

Data type: DWORD.

Each bit of the DWORD represents identical output buffer for analog data in each CS31 slave.

ANALOG_OUT_DIFF (analog out different)

Data type: DWORD.

If PLC A and PLC B analog output buffer is different, then this bit will turn on to TRUE.
