5.2 Communication Setup
5.2.6 How to Set Up the YASKAWA PLC Connection
(1) Before setting
(a) Communication precautions
• Only communications within the same segment are applicable.
Communications via a router or a gateway are not applicable.
• A connection of multiple pieces of network equipment (including GT SoftGOT1000) to a
segment may increase the network load and slow down the communication between the GT
SoftGOT1000 and the programmable controller.
Communication efficiency may be improved by using one or more of the following methods:
• Use a switching hub
• Use a high-speed 100BASE-TX (100Mbps)
• Reduce the number of monitoring points of the GT SoftGOT1000
• To connect multiple GT SoftGOT1000 modules within the Ethernet network, set a different
[PLC No.] for each GT SoftGOT1000.
• Do not use "192.168.0.18" for IP address when starting multiple GT SoftGOT modules.
Otherwise, a communication error occurs in GOT.
