Hi, I made a program for 2 plcs doing the same thing, and the only thing rhey share is a heartbeat. My program worked in testing, and now my xic on every rung doesn't make my OTE true. I did a cross reference to see if I accidentally duplicated anything, but I haven't. My xic is using the first word of a AL4122 io block and I have 50 real sensors hooked up to 5 blocks. I'm not using all 16 available outputs from them, but I do have them in the program for future use. Any ideas why my OTE's no longer work? Thanks
