It is the first experience with m340. I don't find the function to read the information of the PM710.

That I have to use function?

Pm710 and m340, they communicate with Modbus.

Take a look at the READ_VAR and WRITE_VAR functions in Unity. In Unity Pro Version 4.0 there is an additional function called DATA_EXCHG.

 

Dear,

Could you please tell me how to establish the communication between PM710 and PLC M340?

Thanks for your answer.

In fact, with the function "READ_VAR" I've red the records of PM710.

Now, I've tried to do the same using an analyzer "PowerLoguic ION6200", 3 but in this case, all the records appear "-1"

The only difference is on the direction of the records, for PM710 uses 4000 and for ION6200 uses 40000.

What is going on?

Best regards!
