I have a question related to this. Would it be possible to send the run/stop command to the webserver from a third party application through an HTTP Post Command. This removes the need for me to login to the Siemens Webserver to run or stop the PLC. I examined the traffic sent on wireshark when the stop/run button is clicked on the webserver and it looks like it's a bunch of HTTP Post commands to run/stop the PLC What I need help with would be how to craft the HTTP Request required Has anyone done something like this? ------------------------------------------------------------------------------------------ |

Hello I have come across this discussion, have you figured out the start/stop of the PLC using the POST method ? I am doing it in Openness but I dont like that even openness does not have any proper method implemented for the Start/Stop of the PLC. In Openness it is done through download procedure. So I would very much use the same usecase as you have mentioned. To simply call some endpoint with POST method to be able to Start/Stop the PLC.

The API of the S7-1500 Webserver does - for better or worse - cater for this and chapter 5.7 of the S7-1500 Webserver manual has the details. |
