Hi guys,
Update for you. I am at the plant, and with the TI305 programmer when the PLC is turned on and the key is in RUN, nothing happens when I push the NXT or PRV buttons. So it seems like that would indicate the memory has somehow been cleared, right? Is there anything I have to do before I can browse the code if it's there? Also according to the manual, when I press SHF the SHF light should be illuminated to indicate future key presses correspond to SHF but that isn't happening either, the SHF light does not illuminate.
Second, I'm trying to connect to the CPU via the RS232C connection with DirectSoft6, and when I try to connect I see the RX LED illuminate so I know it's seeing the attempts, but it doesn't TX anything. Couple questions:
1. Should the protocol be K Sequence or DirectNET? ECOM seems to only be ethernet, so that doesn't appear to be a legit option.
2. Is there a way to know what the address of the CPU module is? I pulled it from the rack and saw two circular switches and a row of four DIP switches, but I'm not sure what those are used for.
Don't want to jump to conclusions but this seems like a dead CPU to me. Wondering if that sounds reasonable to anyone else.
Thanks again for all the help!
