EtherNet/IP

2.11.1 Outline

EtherNet/IP is available only for the FR-E800-EPA and the FR-E800-SCEPA.
When the EtherNet/IP communication operation is performed through the Ethernet connector on the inverter, data such as
parameters, command values, and feedback values are regarded as objects used for data communication between a master
and slaves. Objects consist of the Class ID, object name, data type, access rule, etc. I/O message communication (cyclic) and
explicit message communication (message) are available.
Some functions are not supported depending on the date of manufacture of the inverter. For details of specification changes,
refer to page 220.
