EtherNet/IP to PROFIBUS DP Linking Device

Published on : Tuesday 30-11--0001

Contrary to an in-chassis module which is physically connected to the PLC, the EtherNet/IP to PROFIBUS DP Linking Device can be mounted close to the connected devices.

This means that it is possible to establish a connection via a single Ethernet cable instead of multiple network specific cables.

All EtherNet/IP Linking Devices from HMS support ODVA’s Device Level Ring (DLR) for ring topology.

Users access their PROFIBUS DP network and device configuration through their existing Studio 5000 software

All configuration is made inside Studio 5000 where there is support for Process Variable Data Tags, as well as manual and automatic generation of named and structured Studio 5000 Controller Tags without any required user logic.

The PROFIBUS Linking Device supports up to 7000 bytes of IO data, 3500 in each direction.

Since the Linking Device operates stand-alone (distributed), it doesn’t affect PLC backplane performance (PLC execution time), even when large amounts of data are transferred. The PLC simply scans the Linking Device as if it were any other I/O device on the network.
