FC7: TM_REV - transfer block for tool change with revolver

Function
After a revolver has been changed, the user will call the block FC7 "FC TM_REV". The revolver
number corresponding to interface number in DB73 must be specified in parameter
"ChgdRevNo" for this purpose. As this block is called, the associated "Interface active" bit in
data block DB73.DBW0 of FC7 is reset after parameter "Ready" == TRUE is returned.
Job executed correctly
If the job was executed correctly, then "Ready" == 1. The user must then set the parameter
"Start" = 0 or no longer call FC7.
Job executed with errors
If the job was executed with errors, then parameter "Ready" == 0 and parameter "Error" == 1.
The job must be repeated in the next PLC cycle. Since the parameter "Start" does not need a
positive edge for a subsequent job, "Start" = 1 remains, because the job has not yet been
completed. See "Call example" and "Pulse diagram" below.
General conditions
● Block FC7 may only be started with parameter "Start" = 1 if an activation signal for the
associated interface (DB73.DBW0) for this transfer has been supplied by the tool
management function.
● A cancellation of a transfer, e.g. by a channel reset, is not permitted.
● Parameter "Start" = 1, until parameter "Ready" == 1 or "Error" == 1
