9.6 Precautions
■1.
Network configuration
Use MELSECNET/H connection (PLC to PLC network), MELSECNET/H connection (PLC to PLC network) in the
MNET/10 mode, or MELSECNET/10 connection (PLC to PLC network) to configure a network including the GOT.
The following networks including the GOT cannot be configured.
• MELSECNET/H (Remote I/O network)
• MELSECNET/10 (Remote I/O network)
■2. Network type setting
• Specify all the network modules on the same network as the same network type.
(MELSECNET/H Mode and MELSECNET/H Extended Mode cannot be mixed.)
• When connecting to MELSECNET/H in the QCPU redundant system, [MELSECNET/H Extended Mode] cannot be
specified as the network type.
■3. Monitoring range
Only PLC CPU of the same networks No. can be monitored in GOT.
For details, refer to the following manual.
➠ GT Designer3 (GOT2000) Screen Design Manual
■4. GOT startup in the MELSECNET/H or MELSECNET/10 connection
In the MELSECNET/H or MELSECNET/10 connection, the data link is started approximately 10 seconds after the GOT
startup.
■5. When a network error occurs in the system alarm
In the MELSECNET/H or MELSECNET/10 connection, when a network error occurs in the system alarm, the system
alarm message cannot be canceled even though the causes are removed.
To cancel the system alarm display, restart the GOT.
■6.
MELSECNET/H network module version
For version restrictions of the MELSECNET/H network module, refer to the following manual.
➠ Q corresponding MELSECNET/H Network System Reference Manual (PLC to PLC network)
■7. Connection in the multiple CPU system
When the GOT is connected to multiple CPU system, the following time is taken until when the PLC runs.
QCPU (Q mode), motion controller CPU (Q series): 10 seconds or more
MELDAS C70: 18 seconds or more
When the GOT starts before the PLC runs, a system alarm occurs.Adjust the opening screen time in the GOT setup so
that no system alarm occurs.

■8.
Connection to QCPU (Q mode)
Use function version B or later of the MELSECNET/H network module and QCPU (Q mode).
■9. Connection to Q17nDCPU, Q170MCPU, Q170MSCPU(-S1), CNC C70, or CRnQ-700
The Q17nDCPU, Q170MCPU, Q170MSCPU(-S1), CNC C70, and CRnQ-700 are applicable to the MELSECNET/H
connection (PLC to PLC network) only.
For connecting the GOT to the MELSECNET/10 network system (PLC to PLC network), set the MELSECNET/H
network system (PLC to PLC network) to the MELSECNET/10 mode.
■10. Connection to QSCPU
The GOT can only read device data and sequence programs by the ladder monitor function in the QSCPU.
The GOT cannot write any data to the QSCPU.
