I have Unitronics HMI and I/O modules at home but not the actual machine (it wouldn't fit in my kitchen).I would still like to edit and test the software. I can't force the analog I/O and test the software. I can tell that the alarms for pressures and levels are working :).
How can one force the analog I/O?
