Hi,
I am new to the PLC business and I have a problem communicating to an Allen Bradley SLC 5/04 PLC. Its internal program might not match the current I/O modules. So I tried turning it on with and without the I/O modules. The result is always the same: Fault LED blinks and I cannot reach it with the RSLogix software through the RS232 port.
Should I wipe the internal program?
If so how?
Could anybody point me in the right direction, please?
Thanks
