P
If anybody know how to communicate with air compressors from Atlas Copco, please help me.
Problem is that communication STOPS after some time( 1 hour to 2 days ) with one compressor, after some time with second and finaly everything is dead.
When communication stops, only power off/on of communication device is help.
Atlas Copco is unable to help with this situation.
They told me that communication stops, when communication buffer is flooded (very robust software).
I send requests every 1500 ms.
That's to slow to flood anything.
There must be another reason to stop.
If you know something, plese tell me.
Notes:
3 compressors are connected in 485 network.
Every compressor has it's own address (1, 2, 3).
I think that my implementation of MODBUS protocol is OK.
It works with other MODBUS devices without any problems.
