By the way an inactive socket could take up to 2 minutes to be free but previously it was for ever.

Was there ever any resolution to this? I am using Virtual Control SL on a ProxMox setup, and I can't get the license installed. I get the same errors reported above.

Post by totorovic on Hard shutdown: no code on device after power on ^{CODESYS Forge talk (Post)}
I think that the .err file is the .app file renamed by Codesys, so it is compiled. We met this behaviour one time, it was because the runtime goes in exception due to bad Ethercat cables.

Hallo, ich versuche einen Roboter über Ethernet/IP in Codesys einzubinden, die Verbindung scheint auch vorhanden zu sein, allerdings erscheint ein Fehler, mit dem ich nichts anfangen kann. Kann mir jemand sagen, was der Feheler "nicht aktualliesiert (Tooltip prüfen ) bedeutet?

That time it was not answered. But yes, it is possible. Search for "Relative movement" properties of the rectangle element. Might need to enable advanced features in the property browser. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html

Same here. plcload in my case is about 7% while running. Watchdog ENIPScannerIOTask was about 200ms. Max cycle around 6ms, normal cycle time 4ms. Probably just increase the watchdog to 2000ms? or so... (Hardware: A Panel from Weintek)

Hello, I encountered this same error. I was able to resolve it by allocating more messages when I open the network driver (ctMessages:= 100). By default it is set to 25.

Post by josul on Web Client HTTPS Communication Issue ^{CODESYS Forge talk (Post)}
Web Client Library Documentation Company: 3S - Smart Software Solutions GmbH Title: Web Client Version: 1.0.1.7 Categories: Application|Utils Namespace: WEB_CLIENT Author: 3S - Smart Software Solutions GmbH Placeholder: WebClient I encountered an issue using this library above. Note it is now part of Codesys IIoT Libraries SL in the form of Web Client SL, but I am not using this version. I was sending Content-Type: application/json, HTTP POST using a HTTPS URL. No issue observed initially, successful operation. At some point operation stopped and the codesyscontrol.log file started to accumulate errors: ERROR: TlsCreateContext2: Failed to save context. An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.
