I figure out how to attaching PLC on remote env.
I used slave address range so that I could find my PLC. But something wrong with my PLC happened that It says linux rev. 1.0 platform type. My actual platform type is Axon M205, and License has been activated but it says not licensed. Tell me what happened to my PLC and how to recover it on remote env. ?

It is remote environment, and I am afraid to lost everything once I detached a PLC.
Can I reattach PLC under porxy or remote connection ?Hopefully I would like to know UDP port number mervis using when
finding connected PLC under the same LAN.

RE: How can I execute program on Mervis
Thanks Martin.
PyModbus worked great to me and I understand how to map variables on Mervis to be placed as modbus tcp touchable.I Still have curious question. I configured 503 port as modbus server, because 502 is already used as another modbus. What is this modbus used for ?
thank you.

RE: How can I execute program on Mervis
@martin-kudláček Thank you for the information. It sounds tough to implement. I finally figured out that if I keep running my application on PLC to collect data and passing result into variables that PLC can touch, it will work equivalent to my question above. Can I do this on Mervis ?
