I've got a situation where certain alarm conditions trip out equipment and the underlying device is either a relay or timer contact that resets as soon as the equipment trips. The integrator says the alarms signal is too short for his plc to "catch". We're using multiple AB-SLC-5/05 with attached panelmates in the field and Intellution HMI as the central SCADA package.
Is the integrator correct in his claim that the plc isn't capable of remembering a very short momentary input? I'd hate to think I'm going to need to go around and put seal-in relays all over the place.
