Input Signals
Signal Function
IN0 to IN6 With these signals, user (PLC) sets the commands.
IN7 This signal is the trigger for Trigger Retry. Set the IN0 to IN6 signals, wait for at least 5 ms, and then turn ON the
IN7 signal. The BUSY signal will be ON while the command is being executed.
Note
The time the BUSY signal is ON is the trigger retry execution time.
Important
It may happen that the PLC is unable to recognize BUSY signal ON because the sample time is slow or otherwise. In
this event, have W0.00 turn OFF at a suitable time.
