Comparison between CJ1W-ETN21 and CJ1W-EIP21

11 posts in this topic

I'm a new member of this forum. How can i access both PLC (CJ1M-CPU23) and HMI (Weintek MT8104iH) remotely via web browser? For OMRON PLC, i'm confused to select which one (CJ1W-ETN21 or CJ1W-EIP21) is better and why? Waiting for a better solution.

The Omron processor/Ethernet card do not have a web server built in.

Yes, I should have read the question more closely. The link that I sent does describe the differences between the two, but neither will support a Web Browser Interface...

I need to know the easiest way to access PLC remotely via web browser. From the conversation i get, 1. Both EIP21and ETN21 support FINS commands, Email, Socket services, but from conversation 'EIP21 doesn't support socket services', is it right or not? 2. EIP21 can act as an Originator (master) to other EtherNet/IP Target (slave) devices. 3. May be, EIP21 with updated hardware design compared to ETN21. 4. May be, ETN21 is safer than EIP21, but why safer? 5. ETN21 is better for PC-PLC communication and EIP21 is better for PLC-Ethernet/ip enabled device communication, isn't it possible to use EIP21 for PC-PLC communication?. waiting for proper suggestions.

Use a touch screen - the Omron NS series have a webserver but only to the touch screen - not the PLC. I answered this for you recently somewhere else or was it someone else?

Notes on a couple of these: What do you mean by accessing a PLC remotely via a Web Browser? Do you mean that you want to see the ladder code in the browser, or do you want to display data from the PLC on a Web page? If you want to see the ladder in a browser, it is not possible. If you want to display data from the PLC on a Web Page, there are many ways to do this. Indusoft is a good solution. It is a SCADA package that will allow you to do so. 1. EIP21 does not support email or socket services. See chart: 4. I am not sure why it would be safer, where did you see this? 5. Yes, you can use either card for PC-PLC communication. It basically comes down to this: If you are going to use EtherNet/IP communications to communicate from one PLC to another or to other "I/O" devices, then choose the EIP21. If not, choose the ETN21.

Hi, You can access a PLC remotely via web browser using an OPC server. There are many companies selling OPC server software. The mostly used ones are Kepware (http://www.kepware.com/kepserverex/), Ingear (http://www.ingeardrivers.com/omron_opc_server/omron_opc_server.htm) and Indusoft (http://www.indusoft.com/). There is a cool product by Opto22 called groov (http://www.groov.com/) which lets you access your PLC remotely via a smart phone or tablet. You also need a web server between the OPC server and web browser. All of these companies provide you a free trial version of their software so you can play and decide what to to buy. Configurations are very similar, so once you learn one of them, you spend less time to configure others. By the way, you can use EIP21 with all of the products I mentioned above. Good luck.

Thank you and brk_h for providing me proper solution. Actually, i want to display data from the PLC on a Web page and brk_h said about the process in comments.One more query about mounting location of ETN21. ETN21 can be attached as the same way I/O modules attached with CJ1M-CPU23 PLC?
