Hello Sir, I have a CNC turning and milling lathe with Siemens 840C V2. I got a problem when I turn on the machine, the alarm 43 ORD 1 PLC CPU failed occured, and no any reaction even push any button. And in the electrical box, when turning on the machine, the light of PCB of PLC was shining but turning off after all. What's the problem it might be? How can I check and repair? Thanks for your kindly information and assistance in advance. ------------------------------------------------------------------------------------------ |

840C!840C, PLC stop alarm 43, this is old topic, you can search in this forum lot of answers. Here is one from Pee our Silver Member "Hi, 840C Diagnostics manual:- F0000 6F: Error number I/O fault on start-up Pee I think you may have hardware defective or HW control card or module power issue, fuses blown. going to "diagnosis-Start-up--check PLC status--menu --PLC information--you will see above message check Doc-on Web 840C "Diagnostics manual"
