20 Ethernet/IP Optional Software
20.1 Overview
The C500 provides the Ethernet/IP industrial network protocol via the L900-501 licencensed package. For
details on licensing this package, please see Section 4.
The Ethernet/IP package provides a number of simple weight and status EIP objects, and more complex
objects which allow access to all Rincmd registers.
20.2 Terminology
Throughout this section the following Ethernet/IP terminology is used:
Term Description
EIP Ethernet/IP
PLC Programmable Logic Controller.
T->O Target to Originator. This is an input in EIP terms (input to PLC). Data is transferred from
device to PLC.
O->T Originator to Target. This is an output in EIP terms (output from PLC). Data is transferred
from PLC to device.
GAS Get attribute single service code used to retrieve an EIP object using explicit messaging.
GAA Get attributes all service code used to retrieve an all instances for EIP object class using explicit
messaging.
SAS Set attribute single service code used to set an EIP object using explicit messaging.
EDS file Electronic Data Sheet file that describes the implicit messages supported by this device.
In this document the C500 is the Target, and the PLC is the Originator.
Ethernet/IP uses the following data types:
Data Type Description
USINT Unsigned Short Integer (8-bit)
UINT Unsigned Integer (16-bit)
UDINT Unsigned Double Integer (32-bit)
SINT Signed Short Integer (8-bit)
INT Signed Integer (16-bit)
DINT Signed Double Integer (32-bit)
STRING Character String (1 byte per character)
SHORT STRINGnn Character String (1st byte is length; up to nn characters)
BYTE Bit String (8-bits)
WORD Bit String (16-bits)
REAL IEEE 32-bit Single Precision Floating Point
20.2.1 Electronic Data Sheet (EDS) File
The C500 supplies a Electronic Data Sheet file to describe the supported implicit (assembly) objects. This file
can be loaded into your PLC software to simplify programming.
Once the L900-501 package has been installed on the C500, the EDS file is available from the following locations:
1. Standard EIP File Object Class (Class 37
H
/ Object C8
H
)
2. C500 web interface (http://<indicator>/eip/c500.eds)
In addition an icon file is available from the C500 web interface (http://<indicator>/eip/rinstrum c500.ico).
