Precautions
Precautions on system
Connectable network
A GOT is connected to the following network systems as a normal station.
• Optical loop system of MELSECNET/10 network system (programmable controller to programmable
controller network)
• Coaxial bus system of MELSECNET/10 network system (programmable controller to programmable
controller network)
When using MELSECNET/H network module
When connecting the MELSECNET/H network module to MELSECNET/10 network system, set the
network type to the MELSECNET/10 mode.
Creating network
For the network including a GOT, create a MELSECNET/H network system (programmable controller to
programmable controller network) with the MELSECNET/10 mode or a MELSECNET/10 network system
(programmable controller to programmable controller network).
The GOT cannot be connected to the following networks.
• MELSECNET/H network system (remote I/O network)
• MELSECNET/10 network system (remote I/O network)
Applicable range for monitoring
A GOT can only monitor a programmable controller and CNC on the network where the GOT is
connected. Note that the routing parameter setting is required when monitoring the programmable
controller CPU and CNC on the other networks.
The routing parameter cannot be set with the GT15-75J71LP23-Z and GT15-75J71BR13-Z. Use the
GT15-J71LP23-25 or GT15-J71BR13 to set the routing parameter.
Version of CNC
For MELDAS C6/C64, use the NC system software version D0 or later.
Starting GOT with CNC connection (MELSECNET/10 connection)
When the CNC connection (MELSECNET/10 connection) is used, the data link starts in about 10 minutes
after starting the GOT.
When an error related to the network occurs as the system alarm
When an error related to the network occurs as the system alarm with CNC connection (MELSECNET/10
connection), the displayed system alarm cannot be erased even though the error factor is removed.
Restart a GOT to erase the system alarm.
Precautions on setup
When changing the switch setting
When changing the switch setting after installing the MELSECNET/H or MELSECNET/10 communication
unit on the GOT, reset the GOT.
Correctly solder the connector for the coaxial cable.
Incomplete soldering causes malfunctions.
