Hello,
I need to control a Eaton DE1 motor driver via ModbusRTU using an E4-UC-12RC1 cpu with a COM-RTU-M1 communication expansion.
Using the ModbusRTU slave module in the project view i'm able to read all registers of the DE1 using the function FC3.
The problem begins when i try to set the de1 in operational mode (motor in run) and trying to change from clockwise rotation and counterclockwise, to do this I have to write a bit of one registrer, using the funtion FC6 but I can't find the way to do this.
With another appliance I was able to do all this things using the function 6xbit and specifying the register and the bit like 6xbit 0000101.
Thanks for all can help.

hi software,
please send a picture of your RTU config.
I think you need only 3 words of incommig data and 2 words to control the DE1
see also the manual MN040018EN Modbus RTU Communication
