I’m currently operating a TSX17 system without issues. However, when I monitor the outputs using a T317, the display shows O00,00 and 03 active, while 02 is blinking, which is the expected behavior. Despite this, the LEDs on the PLC are unlit (the input indicators are functioning), and the relays are failing to activate. A 6-relay module is connected, and while I can manually trigger them—indicated by the T317 flags showing '1'—there are no LED lights or output signals. Do you have any suggestions? If the problem were limited to the main unit, I would suspect a hardware issue, but it seems unlikely that DSF 635 is also faulty. Is there a specific flag or register that might be disabling the TSX outputs? Your advice would be greatly appreciated!
