Example 2: Higher Level Controller (Modbus master) to PLC (Modbus slave)
This project allows a higher level controller (acting as a Modbus master) to read devices and registers from a
PLC and to write to devices and registers in a PLC.
Select a Toshiba T1 PLC on the PLC1 port and a Modbus Slave on the PLC2 port.
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 and coils.
Download this project and communication drivers into Gateway. Test the functionality using a Modbus
Master such as Modscan or SCADA software acting as a Modbus master.
Note: For more details, Please see “Gateway modes” topic.
