Schneider energy meter iEM2150 Modbus

daRedp

Hi,

I installed a new energy meter in my house, this little one has Modbus.
Now I never worked with modbus before, and i really want to integrate this into my Pimatic.

I have a rs485 shield and i have a usb to rs485 converter.

If possible i want to use the shield on the raspberry.
The shield is connected now, but now i get stuck…

How to test connection?
etc…
Please help

thanx

http://libmodbus.org/documentation/ libmodbus is your friend. it works and after some reading through it is easy to use. you could write a simple c program that get’s some parameters and returns the value you want to see.
