Smart LCD MODBUS Salve Product can be accessed by MODBUS Master devices for real-time control and access.
VP variable addressed as MODBUS address
In SGTools, MENU --> View --> Show Modbus Holding Register Address.
can show up the VPs corresponding MODBUS ADDRESS for the display UI.
MODBUS HOST can access those VP in MODBUS address accordantly, in real time.
