AUTOMATION NETWORKS ANC-120
N found this old forum http://control.com/thread/1026157627#1026157627 discussing the difference AB PLC 5 and the Siemens alternative S5; and the comparable difference between the AB Controllogix Gateway and the Siemens S7. Here are some comments that may help to clarify the differences and which solution can be optimal pending your application.
As more devices connect to the Internet, it’s more important than ever to protect industrial networks against cyber security vulnerability.
By Chet Namboodri, managing director, Global Enterprise Business, Manufacturing Vertical, Cisco
Manufacturing is going through major changes, similar to what has happened in the health care and education areas , thanks to all the connection to the the Internet of Everything (IoE).
Ethernet vs. fieldbus: the right network for the right application
The promise of time-sensitive networking has pushed the growth of Ethernet networks, but fieldbus networks still account for more than half of the industrial uses. Which is right for you?

As the Annual ODVA Industry Conference approaches, I’m preparing presentations for the EtherNet/IP Implementors Workshop which will be held in conjunction with the conference.
Most common protocols with Allen-Bradley factory automation

EtherNet/IP: Ethernet Industrial Protocol is based on standard TCP/IP (IEEE 802.3) and correspondences use existing system foundation. Ethernet physical layer innovation is utilized along TCP and UDP ports (44818 and 2222). Its fundamental leverage originates from the inerrant advancement of physical Ethernet, from 10 Mbits/s to 10/100 Mbits/s to 1 Gbits/s and the sky is the limit from there. EtherNet/IP likewise guarantees Internet and venture network for remote control.
