Input
Enable
BOOL
FALSE
A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.
AbbLConCA
Output
Busy
BOOL
FALSE
Operation is running (while output Error is FALSE)
AbbLConCA
Error
BOOL
FALSE
Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.
