♦ Description Gateway is a protocol converter that allows any device with a modbus RTU protocol to talk to a Toshiba T-Series PLC. In some cases Gateway allows the Toshiba PLC to communicate directly with other devices using the other device’s native protocol. Gateway setup software is used to map the registers between the other devices/controllers to registers in the Toshiba PLC.
For Modbus, the 400001 numbered holding registers can be mapped directly to D data registers in the Toshiba PLC. In the above example, 5 data registers in the T1 PLC starting at D101 are written into PID controller modbus registers starting with holding register 400001.
