Correct, my Device architecture says "None" is this position. A missing config somewhere?

Can do. Suspect Visualizations as alarm colours disappear during upgrade, and some error messages related to trend/trace that are impossible to track down...

Post by jroddball79 on PM556-TP-ETH — How to change IP address without overwriting the PLC program? ^{CODESYS Forge talk (Post)}
We have checked open ports. SSH (22) and HTTP (80) are not reachable. The only open ports are: 502 (Modbus TCP — used for lighting control) 1200 (CODESYS runtime) 1201 (CODESYS runtime) We can connect via Automation Builder using the current IP, but we don't have the original project source — only an empty project. This is why we are afraid of doing a full download, as it would overwrite the running application. Is there any way to change the IP through the CODESYS runtime protocol on ports 1200/1201 without affecting the running program?"

Post by hluecke on Codesys Virtual Safe Control mit Weidmüller UR20 FSOE Modulen ^{CODESYS Forge talk (Post)}
Hallo, ich versuche mit der Codesys Virtual Safe Control zwei Weidmüller UR20 FSOE Module zu betreiben. Allerdings läuft das zweite Modul nie an (Diagnosecode 16#C105), auch die Prozessdaten werden nicht aktualisiert. Jedes Modul einzeln läuft, auch bei getauschter Reihenfolge läuft immer das zweite Modul nicht an. Codesys Version 3.5.22.30 mit den aktuellsten Packages. Weidmüller UR20 FBC-EC und die Module auf aktuellem Firmwarestand, neueste Gerätebschreibungsdateien. Was mich dabei auch irritiert, ist dass beim ersten Gerät im E/A-Abbild mehr Ausgänge angezeigt werden, als beim Zweiten. Hat schon einmal jemand so eine Kombination in Betrieb gehabt oder ein ähnliches Verhalten erlebt? Vielen Dank!
