Precautions - Mitsubishi Electric GOT 1000 Connection Manual

2.4 Precautions

1 When connecting to multiple GOTs
(1) Setting [PLC No.]
When the FXCPU is connected to multiple GOTs in the Ethernet network, set a different [PLC No.]
for each GOT.
Section 2.2.3 Setting communication interface (Communication settings)
(2) Setting IP address
Do not use the IP address "192.168.0.18" with multiple GOTs.
A communication error may occur on the GOT with the IP address.
2 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 correctly monitor the controller with the above numbers.
Consult with the administrator of the network before setting IP addresses for the GOT and controller.
3 When connecting multiple network devices, including GOT, to the same segment
The network load may increase, and the communication speed may slow down between the GOT and a
programmable controller.
The following actions may improve the communication performance.
• Use a switching hub.
• Use the high-speed 100BASE-TX (100Mbps).
• Reduce the GOT monitoring points.
4 GOT monitoring access range with ladder monitor function and FX list editor function
The GOT can access only the target CPU with the ladder monitor function and FX list editor function.
The GOT cannot monitor the other stations.
