Write a value via Modbus to servo drive


Recommended Posts

Hello,

I have almost successfully established Modbus communication with a servo drive. I say almost, I cant read the register but I cant write to them. I want to change the speed via a button on the HMI. I get a -11 on the stats tag which is timed out.

Could someone please have a look at the ladder for sending the modus write. Have I missed something?
