I need to read some words from a PM850 (Schneider energy monitor).

But the Twidosoft help does not help much on configuring the EXCH function I need for this.

I wonder if someone can be kind enough to explain it better than the help.

Where do I put the address of the slave device? Where do I put the word address of slave device?
Where do I put the number of words to read?

Best regards

 

In TWIDOSOFT help look a "MODBUS Standard petitions", this table help me very much. If you still can`t comunicate with the PM 850, tell me your e-mail adress and I send a example.
