Resolution
Upon losing communication with the NetController, output modules (DO-4. AO-4 etc) start a 260 *** second timer (4 minutes and 20 seconds), if communication is not restored before the time expires the module turns off the outputs as a safety measure.
For Digital outputs the outputs will be turned OFF. (Invert attribute is taken into account).
For Analog outputs the output value will be set to zero.
*** For access control modules (AC1, AC1A, AC1Plus) the timer is 10 seconds to avoid leaving a door unlocked for an extended period of time.
