(For GT155 , up to two controllers (two channels))
POINTPOINTPOINT
(1) Before using the multi-channel function
This manual describes the procedure to use the multi-channel function, based on the following system
configuration example.
21.2.1 Bus connection and serial connection
21.2.2 Ethernet multiple connection
(2) System configuration when the multi-channel function is used
The system configuration between GOT and the controllers is the same as that of when not using the multi-

For the system configuration between GOT and the controllers, refer to the following.
Each chapter indicating the system configuration
(3) Precautions for hardware
To use the multi-channel function, an option function board is required for some GOTs.
The following table shows the required option function boards.
