My PLC, Modicon TSX 3722 have a serious problem. After the PLC restart, three of four the LEDs indicator (TER,IO,BAT) light on (not blinked). I have read it on manual that indicating CPU fault. I think it caused when my friend plug the PCMCIA Comm Card when the PLC running. The effect is: I cannot connect my PL7 Junior Program (PC) to my PLC. And the question is how to solve this problem? Is there any other restart mechanism (maybe like take out the CMOS BIOS battery on PC) to recover PLC to original / manufacturer setting?
I really need your troubleshooting, coz I'll use the PLC for my last task on my course.
Thank you, before and after.
