I have SLC5/05 with BSN module link to Remote IO via 1794-ASB. The ASB is set to "Hold Last State" for its output. When the RIO cable is unplug from the ASB, the output does hold its last state. BUT when the CPU is power-off, it doesn't hold last state, all output goes to OFF. How to overcome this problem? TQTQTQTQ!
