Channel %1 inter-channel communication not possible
%1 = Channel number
This channel has received a negative acknowledgment from the inter-channel communication because the destination channel number is not known, e.g.: START(x) or WAITE(x) but channel x has not been initialized - Alarm display.
This is an indication of possible discrepancies. The program continues if no acknowledgment is called for.
Clear alarm with the Delete key or NC START.
