Input
ExecuteBOOLFALSE
A rising edge starts the 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.

Output
DoneBOOLFALSE
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
AbbETrig2
BusyBOOLFALSE
Operation is running (while outputs Done and Error are FALSE)
AbbETrig2
ErrorBOOLFALSE
Operation is stopped with error (while outputs Busy and Done are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE. The output ErrorID gives more details about the error.
