Hi everyone I am having issues when I try to pass a value from PLCNext to Spider control. The idea is display this value on a gadget or editbox but I don’t know what is the correct procedure to do that. Could yo provide me information about this topic, a tutorial or documentation? Thank you so much. Regards.
If the Spider control software includes an OPC UA client, then that is probably the simplest way to exchange data. The PLC has other industry-standard interfaces that could also be used, depending on the capability of the Spider control software. There seems to be some information from the manufacturers of this software on the internet. Perhaps they can tell you more about how their software can exchange data with PLCs using industry-standard interfaces.
Hi Martin, thank you for the response. I need to investigate over this point. Anyways, is there any way to develop hmi webserver using html5? If it is son, how can I add this pages to the PLC? Regards.
The PLC is running an nginx web server. Web developers with experience using nginx can develop a HTML5 web application, independent of the eHMI, and host it using this nginx server. Alternatively, another web engine could be installed if required. This all requires general nginx/web development skills, and is not specific to PLCnext Technology.
