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, FZ3 sends and receives data that is the same as the parallel interface to and from an external device.

EtherNet/IP communication specification
The EtherNet/IP communication specification is described. The conformance test applies to Ver.A7.
Before establishing the communication, specify the sending and receiving area settings on the external device. For details, refer to the Instruction Manual of the device being used.

Send area (Command area)
Item | Setting description |
|---|---|
Tag set (connection) | 1 |
Communication direction | Target → Originator (FZ3) |
Tag | 1 |
Data size | 20 bytes (Command area) |
Receiving area (Response area/Data Output area)
Item | Setting description |
|---|---|
Tag set (connection) | 1 |
Communication direction | Originator (FZ3) → Target |
Tag | 1 |
Data size | 48 bytes (Response area + Data Output area) |
Important
- If EtherNet/IP communication is performed with a PLC model that does not support cyclic communication, AssemblyObject setting is required. In addition, depending on the PLC model, AssemblyObject setting may be required even when cyclic communication is supported. Set the AssemblyObject class specification in the following manner: Class ID: 4; Instance ID: 100 [input], 101 [output].
