CM592Control (FB)

FUNCTION_BLOCK PUBLIC CM592Control EXTENDS CM592BaseCommonReq

Send global control commands to a single or all slaves to synchronize process data.

Via using global control commands input or output data of slaves can be synchronized. The commands are selected by different combinations at inputs Freeze / Unfreeze and Sync / Unsync. The slave devices are selected by using individual slave addresses or broadcast address 127 and using PROFIBUS grouping functionality via input GroupSelect.

Input

Execute

BOOL

FALSE

A rising edge starts a single operation, the output Busy goes to TRUE. In the first cycle all other inputs are read and stored, afterwards they are ignored. A falling edge does not stop the operation. After Done = TRUE or Error = TRUE and Execute = FALSE all outputs will be reset. For executing another operation the Execute input needs to be retriggered by another rising edge!

Output

Done

BOOL

FALSE

Operation is completed without error (while outputs Busy and Error are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE

Operation is running (while outputs Done and Error are FALSE)

AbbETrig3

Error

BOOL
