CHAPTER 7 COMMUNICATION OF THE ETHERNET ADAPTER MODULE

7.3 IP Communications over CC-Link IE Field Network (IP Packet Transfer Function)
7.3.1 Deciding the IP address
(2) When the network addresses are different
When the same network address cannot be set for the external device and CC-Link IE Field Network, decide the
IP address within the ranges listed in the following table.
*1 Set the numbers according to the range supported by the external device used.
The range may not apply depending on the external device. Check the specifications of the external device used.
● To transmit communications to an external device having a different network address, the CC-Link IE Field Network
gateway setting and the routing parameters are required. ( Page 124, Section 7.3.7)
● When the request source external device, request destination external device, and modules between them have the
same network address, the CC-Link IE Field Network gateway setting is not required.
● To connect a request source or request destination to a module that does not support the CC-Link IE Field Network
gateway setting, follow the rules described on Page 106, Section 7.3.1 (1). Even if the CC-Link IE Field Network gateway
setting is configured in the Ethernet adapter module, communications cannot be performed.
