Hi,

I'm hoping that someone here might be able to help me figure out what I am doing wrong with setting up a modbus RTU connection between an Autonics counter and a Siemens S7-1200 CPU using the CM 1241 RS 485 module.

I've included photos of the network configuration and the addresses. I keep errors including an 8384 error.

I also have a link for the Autonics counter user manual .

I'm Trying to read and or write two the following addresses:
000001 (0000)

301004(03EB) PRESENT VALUE OF COUNTER

301006(03ED) DISPLAY UNIT

301007(03EE) PS(2) SETTING VALUE

301009(03F0) PS(1) SETTING VALUE

400001(0000) Preset value for PS2

400003(0002) Preset Value for PS2

If anyone can help me out and point out what I'm doing wrong that would be awesome and appreciated. Thanks.

Do you know where the sample Modbus RTU program is located?

Thanks
