Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
It's all good btw, learned that the runtime doesn't isolate the networks that are involved so changing the ethernet subnets away from the Wi-Fi's subnet was all I needed (maybe some config file changes helped, can't say for certain)

Worked for me too. Now I have to find out why I didn't need to do this on very similar systems and what the security issue is

Post by installwhat on Add Event Handler -> Login/Logout Event Handlers ^{CODESYS Forge talk (Post)}
Old question but since I stumbled on it others might. He probably added the function he wants to be called before using the "add event handler". If you don't add it first they will be created with the correct params.

Post by tgf2024 on Dynamic I/Os Mapping ^{CODESYS Forge talk (Post)}
Hi Jinlee, how are you? I have similar application requirements on my project. I have tried dynamic mapping, but the code cannot detect the IO module change when I did hot switch. Do you find the way of how to identify the module change dynamicly? Thanks.

Post by fless on Von SNMP auf IIoT wechseln ^{CODESYS Forge talk (Post)}
Hallo, 1. Willkommen :-) 2. Da hast schon etwas worauf du aufbauen kannst. 3. Da gibt es von WAGO Hilfen wie man Projekte zu Codesys 3.5 migriert. 4. Mit SNMP habe ich keine Erfahrung, kann dir leider nicht weiterhelfen. 5. WAGO hat eine eigene SNMP Implementierung. Ich vermute WAGO entwickelt diese Libary nicht mehr parallel weiter, deshalb die Aussage des Supports. Die Codesys SNMP lib ist in das Paket IoT gepackt worden. Die Library kannst du ganz normal einbinden wenn du die IoT Lizenz für das Gerät gekauft hast . Hilfe findest du hier Wenn du keine Lizenz hast sollte die Lib einen gewissen Zeitraum, iirc 30 Minuten, ohne Einschränkungen im Demomodus laufen. Zu den Detailfragen, das ist eine WAGO Libary da wirst du hier nur mit viel Glück Hilfe finden. Ich würde für ein Retrofit auf die Version von Codesys wechseln, dann bist du auch nicht mehr abhängig vom Hersteller. Grüße

Does anyone know a way to load a CNC program from CNC Editor faster using SMC_NCDecoder? It takes around 7 seconds to load 34 lines of G code and this is a problem for repeating the CNC program.

Post by dkugler on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
is your pointer set to the correct visu client? set a breakpoint in your client iteration and step through the active visu clients like programming system, targetvisu, webvisu,... and check the last usage value of each client

Hi, you have to define how many increments of the drive correspond to one unit in your application. This is done in the Scaling/Mapping Tab in the drive editor.

Post by timvh on Help with DynamicTextGetTextW ^{CODESYS Forge talk (Post)}
First of all you need to enable "Use unicodestrings" in the Visualization Manager. This function returns a pointer to a WSTRING (not STRING). To get this wstring value, do something like this: VAR myWstringVariable : WSTRING(255); END_VAR myWstringVariable := myResult^; // this is dereferencing the pointer to the WSTRING.

Post by timvh on Array of Program ^{CODESYS Forge talk (Post)}
You cannot create an array of Programs. Create a Function Block for this purpose instead of a program. You can create an array of FB instances and call each instance in a loop.

Post by thedertom on Help with DynamicTextGetTextW ^{CODESYS Forge talk (Post)}
Hi TimvH, thanks for your reply. Yes I got that figured out now. However: in "myWstringVariable" it will only store the first character of the text. How do I get the full text?
