Precautions

■1. When connecting to multiple GOTs
(1) Setting PLC No.
When connecting two or more GOTs in the Ethernet network, set each [PLC No.] to the GOT.
➠ 4.3.3 ■4. Ethernet setting
(2) Setting IP address
Do not use the IP address "192.168.0.18" when using multiple GOTs with the GOT 1000 series mixed.
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 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.
■3. When connecting to the multiple network equipment (including GOT) in a segment
By increasing the network load, the transmission speed between the GOT and PLC may be reduced.
The following actions may improve the communication performance.
• Using a switching hub
• More high speed by 100BASE-TX (100Mbps)
• Reduction of the monitoring points on GOT
■4. When setting Port No.
By setting of the OMRON PLC, set the same [GOT Communication Port No.] setting as that of [FINS UDP Port] of
CXProgrammer.
