There are two communications ports on the Gateway, labeled PLC1 and PLC2. Each port can be
configured for either RS232 or RS485 operation. Gateway can communicate through either the T-Series
RS232 programming port or the RS485 computer link port.
Gateway is setup using simple MS Windows setup software. The software allows devices/registers from
one device to be mapped to devices/registers of the other device. 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. 3 Holding registers in the PID controller are
written into the data registers of the T1 starting at D0 (D0 –D2). It is also possible to control the priority
and frequency of the data transfer using the Gateway setup software.
