Gaurdlogix 5380 tied into 1734-AENTR. Safety scanner ossd1 and ossd2 are in I0 and I1 respectively. Common is hooked to 4&5. When we reset the scanner we get 24vdc from the scanner at the terminals of I0 and I1. But niether input shows to light up nor swap states in the program. Kinda stuck on this one. i may try to swap in a new input module and see if it works.
