I have three parallel inputs and a set coil output on one rung. The problem is the set coil will come on for no reason. None of the inputs have become true, But the coil will "set" on its own.
Using LD-PC is new to me however i am using a 90-30 I/O Rack, The machine is working fine except when this bit comes on, As it is an alarm bit so it halts everything. I have tried everything with no luck.
Get this: I can block one of the paralleld inputs with a "ALWAYS_OFF" and it will work fine, So you would think wiring problem huh? NOPE! it is a NC input so i Jumpered the input straight to VAC. Still acts the same !! Thinking input problem i even addressed the inputs to a different card, Same response!!
The set coil just does not like the input for whatever reason...
I have deleted all 5 rungs that are involved and re-written them, Still the same !!!
Anyone ever seen anything like this before ???
QuikPanel control using a 90-30 rack, Cimplicity ME software.
All inputs are 120VAC,
