Introduction

This Application note explains, how to configure a generic modular adapter, when the entry for "ProxyConnect" is not described in the Ethernet/IP Slave Device Description (EDS).

Please refer to the following FAQ: "Why does my modular EDS file not work?" → https://hilscher.atlassian.net/wiki/pages/viewpage.action?pageId=113541135

As an example the Allen Bradley Point I/O Module Adapter "1734 AENT" is used, together with the fitting Point I/O Modules "1734 IB8" and "1734 OB8E".

Hardware configuration

The EDS File of each module is needed for further configuration of the Generic Modular Adapter.

These can be found on the Rockwell Automation Page:

https://www.rockwellautomation.com/de_DE/detail.page?pagetitle=Electronic-Data-Sheets&content_type=overview&docid=11432fc64a2a887b85011582be53806b

Software Configuration

Add Modules

In SYCON.net, add an EtherNet/IP Scanner (e.g. CIFX RE/EIM) and then an ENIP Modular Generic Adapter to the network.

Image Added

Open the Configuration Window of the Modular Generic Adapter and choose "Module" in the Navigation Area.

Change “Slots in Rack” to "4" and add the modules.

Since 1734-AENT covers 2 Slots, skip one slot between 1734-AENT and 1734-IB8:

Image Added

Configure 1734-IB8

Specify Connection

EtherNet/IP is a connection-oriented protocol, therefore the connection should always be specified first.

Open the EDS for 1734-IB8 and go to the section [Connection Manager], assuming that Connection23 (Input only) will be used:

Image Added

Configure connection settings

Please choose "Connection" in the Navigation Area of the Modular Generic Adapter. Select  the Module “Slot<1> 1734-IB8”.

Decode the fields "trigger & transport" and "realtime format", which are defined in Connection23.

Image Added

These parameters describe the connection variables, which have to be filled in the Connection configuration window in Sycon.net.

The free Tool "EZ-EDS" from ODVA (https://www.odva.org/software/EZ-EDS-Download), can be used to decode the parameters easier.

Therefore, open the EDS by selecting "File → Open…”.  Select "Generic EDS" as EDS type and ignore the upcoming error messages.

When the file is successfully opened, select “Connection1” in the left tree view.

The name “Connection23” in EDS file is automatically converted to “Connection1”.
