HMI Webserver PLCNext

Hi, I need to know the maximum number of clients allowed on the web server, Thanks.

Hi Cris, Sorry for the delay. Do you mean the nginx web server generally, or the HMI service that runs on nginx? ~ Martin.

Martin, if possible, both please. Cristobal Martinez

Hi Cris, Sorry for the delay. There is no fixed limit on the number nginx clients, in general. For the PLCnext HMI web service, there is a fixed limit of 30 clients logged in at once. For non-logged in clients, there is no fixed limit. Performance will be limited by the resources of the hardware. Limiting factors could include for example the number of variables/objects/dynamics on their pages and how busy the eCLR is with control code. As the number of variables and the number of clients increase, the performance of each individual HMI client decreases. I hope this helps. ~ Martin.
