Is there any way to find out the I/O?
When i try to download my backup program, it shows me following error in bottom of CodeSys.
#251596803: '-1970-01-01 00:06:11 E4:I/O-Bus 'Timeout while updating the I/O data at program start'
Hi
Exactly as the program shows you:
some of the I / O are not responding to communication with the CPU.
How many I / O do you have in your PLC?
Are there any false contacts / dust / humidity in the connections between the communication bases?
Have you tried cleaning the base connectors with contact spray?
The extended error code, based on the tables I sent you on the answer, should help you understand which module is not responding
Thank you, It worked after replacing one module with terminal base.
Very well, I am glad that my suggestion served to solve your problem
