Hello, i've suddenly experienced a communication failure for slave 1 and then for slave 2.I've already checked and tight all ID jumpers on all slaves and UCMs.From the keyboard i heard "Communication Error, 34".See also the screenshot attached.The Comm failure for both slaves and the comm restore continue forever.The green LEDs on both slaves stay on, then flash once, then i hear the Comm failure alarm. Any advice on how to solve this?
Some advices: Slave 2 is connected via the 4 pole cable to the Slave 1. Slave 1 is connected to the main board via the KA KB 2 pole connector. Slave 1 has its own battery and transformer and powers Slave 2 too.
Below, the log:03/17 13:58 ....all normal before, then:
