Example 3: PLC (Modbus master) to Other Device (Modbus slave).
This project allows the PLC to read the current temperature from the PID controller and write a set point into
the PID controller.
Assume Modbus Holding register 400001 contains the actual temperature.
Assume Modbus Holding register 400002 is for the set point.
After the PLCs have been selected for both Com ports, click on the Edit Button.
The Block edit screen should appear.
Create blocks for mapping registers.
Download this project and communication drivers into Gateway. Test the functionality using a T1 (acting as a
Modbus master) and a PID loop controller. Read the actual temperature value in data register D0000.
Change the set point by changing the value in data register D0001
