I have a TSX17 running happily.
When I look at the outputs with a T317, it shows O00,00 and 03 on, and 02 flashing, which is how it should be.
However, the leds on the PLC are off (input ones light), and the relays are not activating.
It has a 6 relay module attached, and again, I can force them on, T317 flags show '1', but no led and no output.
Any thoughts?
If only main unit, I would suspect hardware, but DSF 635 can hardly be faulty too?
Is there a flag/register to block TSX outputs?
Please advise!
