'WriteMultipleRegistersResponse' object has no attribute 'registers'

[oryxr]

I use RTU serial sync communication with pymodbus on master .
It works perfectly but sometime this error occur :
ModbusExceptionError with 'writeCoils': IllegalValue and after I have this errors recurrents : 'WriteMultipleRegistersResponse' object has no attribute 'registers' or this error too:
'WriteMultipleCoilsResponse' object has no attribute 'bits'
I can't repeat error, but when I restart code (master or slave) the error disappear
What do you think
Thanks and sorry for my poor english

what version of pymodbus are you working with ?

[oryxr]

pymodbus 1.2.0 branch python3, same error with python2

[dhoomakethu]

Please use the latest v 1.3.0rc1 , it is supposed to have a bug fix for similar problem. Let me know your findings

I test with the new version and I have the same error

always this errors with rc2

Are you trying this against any real modbus device ? Can you give some more information regarding your setup and baudrate?
