Hi is there any special modbuus block in wago RTUs for establishing communication with Automation Direct HMI on modbus RTU.
Any guidlines will be appreciated.
You'll have to consult your WAGO manual for that info, they should provide a Register to Modbus Address Map for you to use. Then you'll need to create tags in the HMI using those addresses. Should be a simple operation, if you provided your actual part numbers than you might receive more help.
