Hi Sony,

The function code ReadInputRegisters can read several registers, so you should be able to have just one module with six ChanIi below. You specify the address for the first register and the following 5 will be added in the message. Six modules will also work but then you will have six messages instead of one.

Hello,
Today I make data collection trial and I think correct.
I attach a picture to explain.
In the module is for setup 'device slave address' and starting of 'element address'
Under module is element address and down sequently
Please correct me if I'm wrong
