8.3.4 Accessible range
The accessible range differs depending on whether the conditions listed in Page 149, Section 8.3.2 (1) are met or not.
• 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,
such as an Ethernet adapter module, supporting the CC-Link IE Field Network gateway setting. Configuring
the CC-Link IE Field Network gateway setting allows communications to be performed. ( Manual for the
module supporting 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 supporting the CC-Link IE Field Network gateway setting is not required to be connected.
