Hi,

 

Had anyone Have this problem, where the Siemen 226 CPU (s7 200CN) 6ES7 216 2BD23 0XB8 disconnect the Proface Model 3580207-02 AST3301-B1-d24 cause Damage to PLC comm port?

I had just replace the CPU after the machine running for 20 years, it was running fine for 3 months, then Comm Port 1 fail, then i replace the touch screen port to Comm Port 0, it run for few more month also the same problem occur. the CPU is still on run mode.

Can it be the grounding issue? or some other thing i need to check?

i have replace with new CPU, it running ok at the moment

Thank you

This problem occur due to HMI COM Port block due to Earthing or Internal Power supply voltage.............

you should  download empty program in HMI on Force Mode and after switch on/off and after that u download your program in HMI

Thanku
