Hey all, if pin 50 (+24E) was shorted against pin 28 (COM-B5) of CRM2B, so basically a full on +/- short, would it fry the board or is there a fuse somewhere. After the short occurred the IMSTP alarm came on. I assume there is no power going to pin 1 of CRM2A anymore. Also between +24E and 0v is now only showing 5 or (.5 i cant recall) volts. HELP
Thanks in advance.

Yes they have fuses, 2A I think.
If fuse is good, then need more info. There are multiple boards with multiple ways for +24E to connect.
Which process board?
Which R model controller?
Is the controller A- or B-Style?If fuse good, visually check the front and back of the process board and look for a burnt trace.

I recently experienced a short in my EE conector. (RJ2 controller). It took out two small eproms on my PLC board. Thanks to RacerMike for pointing me to them. Replaced the eproms and the associated problems went away.
Just another place to check.
