Requirements and Conditions for the Use of EtherNet/IP Slave Terminal
This page describes the requirements and conditions in the following two subsections.
About Input/Output size
Data transmission size by EtherNet/IP slave terminal is 4 bytes larger than the Input/Output size of WINCAPSIII.
This 4 bytes is system-reserved data for the EtherNet/IP slave terminal, not available for users.
If you configure an EtherNet/IP slave terminal with master configurator, set the data size 4 bytes larger than the Input/Output data size of WINCAPSIII.
The following shows an example.
| WINCAPSIII setting | Configurator setting | |
|---|---|---|
| Input Size | 32 byte | 36 byte |
| Output Size | 32 byte | 36 byte |
System-reserved data is assigned at the start of the input/output data. Viewing from the master, the first data of the EtherNet/IP slave terminal is 4 bytes later from the first data.
The following shows examples.
- Input Data
- Output Data
Configuration without using EDS file
If you perform master configuration without using EDS file of EtherNet/IP slave terminal, you need to set the instance number. Enter the following numbers.
| Instance Name | Instance Number |
|---|---|
| Input | 129 |
| Output | 130 |
| Configuration | 128 |
The following shows an example.
