Posted 9 Mar 2016 I am exploring a new machine with NX701 CPU. If I browse to the CPU on port 80 I get an authentication popup (username / password) which suggests that there is a web server running on the CPU. I can't find the username / password on the web or in the Sysmac Studio CPU configuration. Anyone know? Many thanks. Share this post Link to post Share on other sites
Posted 10 Mar 2016 Well, something's responding to HTTP requests on port 80. I wonder what it is. Share this post Link to post Share on other sites
Posted 11 Mar 2016 No idea. You can access the memory card via FTP, but you actually have to enable that and download the program to activate it. And you set the user name and password in the project. No idea why it responds on port 80 unless someone moved the FTP there from port 21. Share this post Link to post Share on other sites
Posted 12 Mar 2016 I can understand what you're thinking, but no there are no web pages served by the NJ. The NJ communications protocol uses "Web Services" which means packets are sent via http port 80 and numerical data returned. That is what this web server on port 80 is for.

Posted 26 Jan 2019 I don't know. I'm using the NX701 and it doesn't have the OPC server. Share this post Link to post Share on other sites
Posted 28 Jan 2019 OMRON manual W506-E1-20 (NJ/NX-series CPU Unit Built-in EtherNet/IP Port) talk about a service named "HTTP Server" which use TCP protocol on port 80. No other informations. Share this post Link to post Share on other sites
Posted 13 Jan 2023 Sysmac Studio use the HTTP protocol to get data variable from NJ/NX controller not EtherNet/IP. The webServer is LightTPD (https://www.lighttpd.net/). The Omron protocol over HTTP seem not to be documented.

Posted 24 Jan 2023 Last NX firmware version 1.50 does not used HTTP protocol, now using TLS! The port 80 does not respond. The web server seem to be gone. 1 person likes this Share this post Link to post Share on other sites
