pszczepan Posted October 1, 2012 Report Posted October 1, 2012 Hi, When I switch ON PLC after a while PLC doesn't make any self-test - since power is ON LED's are like below. TER LED is ON and I cannot even be online with PLC to check errors. If they all are ON it means that CPU is corrupted. Quote
Crossbow Posted October 3, 2012 Report Posted October 3, 2012 I think all lights on meant a hardware fault, but can't remember. You can get the manuals from Telemecanique's website and check. Quote
