Schnider Electric JR-900 Radio Network ModbusTCP and RTU

I have a JR-900 Radio network about 70 remote radios.
My Modbus RTU/TCP (RTU to TCP Encapsulated) Remote devices have great communication statistics around 90% good.

But My strictly Modbus TCP devices has only a 40% good poll rate.

Has Anyone ever seen this, or if anyone has any insight to why this would be occurring.

Is this a multi-master setup on the Modbus Network or just one network?
If multi-master interference could be a cause. See the operation manual.

I would also try reducing the overall speed to see if the poll rate % increases.
Just a couple of thoughts.
Regards,

Your modbus/TCP master is probably tested to work with much lower latency networks than the one you use with radio communication, maybe you have a timeout problem.

Look if that master has the possibility of increasing the timeout
