My MC403-Z is setting as follow:
I am a beginner by using motion perfection with trio basic.
I wish to read the content from my modbus slave device.
I am using RS485 with 2 wires
The function 0 & 1 & 2 for MODBUS command looks fine for me.
But I am NOT ABLE to perform function 3 with the correct result.
My command to the slave node 3 is $030306270002756A
Follow is my program:
MODBUS(3, -1, VR(modbus_handle),$030306270002756A,25)
What's wrong with my command?
Is there any other way to send commands to my RTU slave devices?
