thanks for replying. as you know there are just 2 red leds: the batt.V and the cpu-e. As i am writing this, i am not 100% sure if both the led where on. after disconnecting the cable and taking off/on the supply. the leds are off again

Hello guys I was verry happy with my (borrowed) red SC-09 cable(D9-D25 red beijer). I connected it to the PLC (FX-80MR-DS) and was able to douwnload en load. Then i went away for dinner en when i came back: 2 red leds on the plc and a communication error on the PC. The D25 connector was a little warm. Can't get any communication anymore. Is this a known problem? What can i do to avoid it? I did not connect the little grounding cable which comes out of the D25. Is this critical and what is the best place to connect it? hope someone can help me!

Ok.so the grounding cable is not the problem. yes, i have tried it with another plc , but the same results: no communication
