Hi all,
This is my first project using Modbus RTU on a project to interface a HMI and multiple drives and I need guidance on proper addressing. I have a RedLion G310 HMI configured as the Master and four Control Techniques SKD3400750 Drives daisy chained RS485 to be the slave devices.
Configuration:
HMI Master
SK1 - Node 1
SK2 - Node 2
SK3 - Node 3
SK4 - Node 4
If I wanted to write an integer value to a holding register of all the drives at 400077, how would I distinguish which drives I was sending to? Where would the node information be added to "400077"? Any explanation would help and greatly appreciated. Thanks.
