Communications Processing Flow

In EtherNet/IP communications, the following five communication areas are set in the PLC.
Input tag set for the
Sensor Controller
Output connection to
PLC
The above five areas are set by Support Software that can perform tag data link settings such as Sys-
mac Studio Ver. 1.10 or later, or Network Configurator. How to specify is either I/O memory addresses
or variable names.
For details of the tag data link settings by Network Configurator, refer to 2-3-8 Setting Tag Data Link
on page 2 - 208.
Moreover, when a non-OMRON PLC or EtherNet/IP unit is connected, download the EDS file for the
Sensor Controller from our OMRON website and follow the procedures in the user's manual for the
external devices to be connected and in the instruction for the software to set tag data link.
The flow of EtherNet/IP communications between a PLC and the Sensor Controller is as follows.
