Hi.

I have a problem with the TSX17-20 PLC - the "RUN" LED indicator is ON (green)and output 7 on LED display is blinking (alarm).

When I am testing all inputs with 24 volts nothing happens at all and
I have tried another TSX17-20 with same result.

Is it a problem with the EEPROM or the CPU board ?

Thanks in advance

Not familiar with that PLC, but if I were to take a rough guess
based on your info I would say you might have a guard open on machine. Normally the green run light indicates PLC is operating and input 7 would see a input which might be tied to a timed flasher signal.
