1.3 IP Packet Transfer Function
Access range
The access range differs depending on whether the IP address setting conditions are met or not. (
IP address setting)
• When one of the Ethernet devices does not have an IP address that does not meet the IP address setting rules, both of the
request source device and request destination device need to be connected to a module compatible with the CC-Link IE
Field Network gateway setting, such as an Ethernet adapter module. Setting the CC-Link IE Field Network gateway allows
communications to be performed. (
Manual for the module compatible with the CC-Link IE Field Network gateway
setting used)
• To perform communications between Ethernet devices with an IP address following the setting rules, a module compatible
with the CC-Link IE Field Network gateway setting is not required to be connected.
