Good day. Recently, I replaced a EXM 438-1 with another one (of exactly the same type). But when the system is powered up with the new EXM in place, LED 9 & 10 of the EXM goes high, and FM starts indicating INTF and IF (and obviously, it does not go in to RUN mode). According to book, LED 9 & 10 does not have any purpose, so they should remain low. If hardware config of the system is viewed in online mode, then it shows an error indication on the FM module, and displays a message the new EXM module is configured but not available. I even tried to re-download the hardware and then putting the PLC once again in RUN mode, but these errors were still there. I want to know, that if I am doing any thing wrong over here, or is there something else to be done, or I need to check something else. I am attaching a couple of pics for reference. Thank you.
