Information of application with many PLCs connected in Ethernet?
Hello I am interesting to get information on an application with many PLCs connected in Ethernet (tcp/IP) network .Or in literature of this type of network

Hi Moti, you may find inforation in: www.system302.com. It is an open standards system based on HSE protocol.

I would recommend you learn more about CC-Link (http://www.cc-link.org/eng/t_html/index.html). CC-Link provide seamless message communication from the device to the enterprise and everything in between. CC-Link IE Control and CC-Link IE Field are 1 GB Ethernet network solutions that utilize standard cables and connectors. Let me know if you want additional information.

What is it that you need?, Do want to implement this kind of project or are you just looking for information for homework?

The model of plc will determine the network protocol. It is not recommended to use commercial tcp/IP hardware due to the lack of deterministic timing. All of the major plc/package mfg have data on there web sites.

I"m not sure if I understand fully but I would probably use a REDLION DataStation Plus as it has over 200 supported protocols and can talk up to 7 or more PLC's at the same time exchange data. Check here for the datasheet: http://bit.ly/bgdMXx

There are many schemes available. First you need to define your platform like Simatic, Rockwell, Omron, Mitsubshi, etc. Most PLC's offer ethernet connectivity. I have used the Siemens Simatic S7-400, Rockwell RS5000, directly on Ethernet. A few years back I used the CTC HMI unit to build an Ethernet back bone with Mitsubishi PLC's connected to dedicated HMI's with a serial port link and networked multiple HMI/PLC sets on Ethernet. Now there are a number of options available to use Ethernet to link PLC's to VFD's and Remote I/O racks. Go to the manufacturer's web sites for most of this.
