Connection to the remote I/O station
(1) Monitor function
The GOT can monitor only the following GOT functions.
• Monitor function
• System monitor function
(2) Clock setting of the GOT
The GOT does not allow the PLC CPU clock of the master station to be set in the clock setting of the utility. The
master station clock will not change even if the clock setting is made. Use GX Works2 or similar software to set the
PLC CPU clock of the master station.
■7.
Connection to MELSECNET/H
For monitoring the QCPU redundant system when connecting to MELSECNET/H, use QCPU of function version D or
later, with the upper five digits later than "07102". Also, use GX Developer of Version 8.29F or later.
■8.
Option functions including the ladder monitor
A message "Unable to communicate with CPU." is displayed when system switching occurs while an option function
such as the ladder monitor is used.
■9.
Monitor display speed
When the control station of the MELSECNET/H network or MELSECNET/10 network fails and is taken over by a
station outside the QCPU redundant system in the MELSECNET/H connection or MELSECNET/10 connection, , the
timeout is detected as the system alarm.
If this occurs, the monitor display speed may slow down.
■10.
In the direct CPU connection
In the direct CPU connection, the GOT fails to automatically change the monitoring target in the following cases.
• When the power supply to the CPU where the GOT is connected is OFF
• When the cable connecting the GOT with the CPU is broken
• When the tracking is disabled

When the QCPU redundant system is in the debug mode
When the QCPU redundant system is in the debug mode, do not make the MELSEC redundant system setting for the
GOT side when connecting the GOT.
