Brian Taylor, Field Applications Engineer at Novanta IMS discusses the Liberty* MDrive Ethernet integrated motor+driver+controller with multiple networking protocols available. The demo shown uses the LMD Ethernet products with PLCs from: Siemens (Profinet), IMS (Modbus/TCP) and Allen Bradley (EtherNet/IP). Description of the demo
The last post in this series we examined the major protocols used for automation and control in industrial Ethernet networks. Today we will examine the protocol with highest percentage of industry usage: EtherNet Industrial Protocol, or EtherNet/IP™. EtherNet/IP™ was introduced by Rockwell Automation in 2001. Over the last 9 years it has grown into the

In the last posting we took the 5000 foot view of industrial Ethernet and examined why using it for industrial networks is such a good idea. In this posting we want to zoom in and drill down into what makes Ethernet devices play nice together on an industrial network: Protocols.
When the Ethernet standard (IEE802.3) was first adopted in the mid-1980s it was considered unsuitable for industrial automation networks because of its non-deterministic nature. Networks using RS-485 and RS-232 ruled the industry.
