7.3.1 Deciding the IP address
This section explains how to set an IP address to perform communications over CC-Link IE Field Network.
(1) When the network addresses of the request source external device, request
destination external device, and modules between them are the same
Communications can be performed with the minimum setting by setting the same network address of the IP
address in the request source external device, request destination external device, and modules between them.
The IP addresses of the request source external device, request destination external device, and modules
between them must meet the rules below. Especially, pay attention to the setting ranges of the third and fourth
octets.
*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 the external device, the routing parameters are required. ( Page 109, Section 7.3.4 (1))
