6.3.1 When connecting GOTs to MELSECNET/H remote I/O station
For MELSECNET/H network connection, connect GOTs to a remote I/O module or serial
communication module mounted on a MELSECNET/H remote I/O network remote I/O
station.
The GOT cannot be connected to the base unit of a remote I/O station (bus connection).
When connected to the base unit of a remote I/O station, the GOT will result in a
communication error.
(1) GOT connection methods
Make sure to connect GOTs to a remote I/O station via "CPU direct connection" or
"computer link connection".
For CPU direct connection, connect the GOT to the remote I/O module mounted on
the remote I/O station via the RS-232 port.
For computer link connection, connect the GOT to a serial communication module
mounted on a remote I/O station via the RS-232 port.
