Control/Output Through Ethernet/Ip - Omron FZ4 Series User Manual

Control/Output through EtherNet/IP

This section explains how to set the required communication specifications when using EtherNet/IP to
communicate with external devices.
EtherNet/IP is a multi-vendor network for the industrial community using Ethernet that is managed by
ODVA (Open DeviceNet Vender Association).
A cyclic communication (tag data link communication) with an EtherNet/IP device that supports the class
1 communication of the EtherNet/IP standard can be achieved without a user program. Using the tag
data link communication, FZ4 sends and receives data that is the same as the parallel interface to and
from an external device.
The message communication function is used when communicating with a PLC that does not support
tag data link communication or when using functions, such as character string output, that are not
supported in tag data link communication. Message communication can be performed either by
exchanging the same data as for tag data link communication using AssemblyObjects or by sending and
receiving commands equivalent to non-procedure commands using FZ4-specific VisionSystemObjects.
EtherNet/IP communication specification
7
The EtherNet/IP communication specification is described. The conformance test applies to Ver.A7.
Before establishing the communication, specify the output and input connection settings on the external
device. For details, refer to the Instruction Manual of the device being used.

[Note]
[Note]: Up to 502 bytes of data can be set, but the current version should be used with 20 bytes (default)for
output connections and 48 bytes (default)for input connections.
Important
If instances are to be specified without using the EDS file, an AssemblyObject must be set as specified below.
●
When using the 2-line random trigger mode, be sure to set 102 and 103.
