8.5 Precautions
 When setting IP address
Do not use "0" and "255" at the end of an IP address.
(Numbers of *.*.*.0 and *.*.*.255 are used by the
system)
The GOT may not monitor the controller correctly with
the above numbers.
Consult with the administrator of the network before
setting an IP address to the GOT and controller.
 When monitoring to another network No. on
the same line
When the network No. of the GOT does not match with
that of the PLC on the same Ethernet, the PLC cannot
be monitored. When monitoring, set the same network
No. as that of the GOT, or connect a Ethernet module to
the PLC and set the routing setting to monitor as other
network.
When the Multi-channel is supported for GT16, set
each channel with the networks No. to monitor.
 Remote password for QCPU
Do not set a remote password for QCPU.
Monitoring with GOT becomes unavailable.
 When connecting to Built-in Ethernet port of
Built-in Ethernet port CPU
Connect to GOT after turning on the network equipment
such as Built-in Ethernet port CPU or HUB to enable
the communication.
When the communication with Built-in Ethernet port
CPU is not available, a communication error may occur
on the GOT.
 The number of connectable CPUs for one
GOT
QCPU : 128 CPUs can be set (10 or less CPUs are
recommended)
FXCPU : 128 CPUs can be set (10 or less CPUs are
recommended)
