Hi,
I am trying to connect Communicator to our special PLC using Modbus.
I was able to get it to work with Standard commands (where it asks user to enter the parameter and sends appropriate command).
Now I want to have a command, that would not require user to enter any parameter, but would send the command with predefined constant parameters.
Example:
PLC supports a “set color” command where we send (using 0x10 Modbus function, registry address 0x240 a binary command of 3 bytes <red><green><blue>).
I want to create a control in the schema, where user presses a button “Set to blue” and the command would be sent with 255 0 0. Then there would be a button “Set to red”… you get the point.
How shall I configure that? Found no doc on Command values.
