Ethernet, the Perfect Wiring Solution for Industrial Automation

Yesterday post discused the rapid growth of Ethernet in Industrial Automation.  Today’s follow-up points out the most dramatic reason why Ethernet buses (i.e. EtherCAT) are rapidly replacing traditional bus technologies. It’s all about wires, or actually the lack of wires.

Below are before and after diagrams of a traditional control system and an EtherCAT based control system. The difference is stark; the benefits are obvious.  Having the communication and safety bus combined on inexpensive Ethernet cabling streamlines complex and expensive wiring harnesses. The simplified cables alone translate into significant savings in the bill of materials.

In addition to the cabling savings, ease of installation and maintenance also provide compelling reasons why Industrial Automation customers are moving so quickly to Ethernet based communications.

It has taken a while but Industrial Automation is finally able to fully leverage Ethernet as a cost effective, flexible, and powerful communications solution.  I predict it won’t be long before we see wireless proliferating throughout Industrial Automation.
