CP4 Direct I/O PLC status picture request | 19 April, 2012

Hi all,

I'm still trying to get our CP4 to work. I've found 3 relays with bad contacts but replacing them didn't help (weird). I'm trying to check the input lines to the Direct I/O PLC. Could someone take a picture of the LEDs (IN1-3 and OUT1-3) after power up and before pressing the reset sw. I would also ask if you could take a picture after you press the reset button (before pressing start to zero it) so I can compare them to ours (send it to dsp1024 at yahoo dot com please).

Thanks to everyone
