Dear Sir,

I faced frequent communication error with the devices set up as in attach file.
There is no internet connection in my network. It is reading and writing from PLCs to PLCs,

Please advise what could have gone wrong.
I would also like to have an updated firmware, if there is any.

Thank you
Regards   
Calvin Lee
