5.1 Project Setup
This Chapter explains, how a simple Gateway project can be created and tested. To develop a Gateway
system, select appropriate Gateway model depending on the system requirements. A new project can be
created as follows:
1. Define the Gateway System:
1.1 Protocol of Device(s) connected to PLC1
1.2 Protocol of Device(s) connected to PLC2
2. Load Microsoft Windows® based Gateway Setup software.
3. Select devices to be connected on two ports.
4. Define Blocks for data transfer.
5. Set the communication parameters for the selected devices.
6. Set conditions for block execution if required (Repeat Cycle, Control Word etc.)
7. Apply power to Gateway.
8. Download the Project and Communication Drivers into Gateway.
9. Remove Configuration Cable from PLC1 Connect Gateway - Device cable to PLC1
10. Test system.
Following Gateway examples show detailed setup for common Gateway configurations:
Example 1: PLC to PLC Communication.
Example 2: Higher Level Controller (Modbus master) to PLC (Modbus slave)
Example 3: PLC (Modbus master) to Other Device (modbus slave).
5.2 Example 1: PLC to PLC Communication
This project reads the inputs of the PLC on PLC1 and writes to the outputs of the PLC on PLC2
Select the Toshiba T1 PLC on both Com ports.
After the PLCs have been selected for both Com ports, click on the Edit Button.
NOTE: “Edit” button has been renamed as “Configure” in Software Version 2.00B or later.
