Post by ph0010421 on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

Thanks, that's what I thought initially. The point is that I can't select a String type variable. See the attached image

I'm trying to add an alarm configuration object to a project in Codesys 3.5 SP12 however when I right click on application and try to add object there is no option for it. Is alarm configuration avaiblible on this service pack?

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

Only idea I have is that new textlists are not loaded with an online change. When you add them, maybe you always have to do a full download first.

Hi, Runtime goes in exception before the shutdown ? Do you have a .err file which is created ? (located in the folder of the .app and .crc)

Hello I'm using the MQTT_Client_SL library. Very good so far. One of the inputs to the MQTTClient FB is hCert (RTS_IEC_HANDLE). Which function do I need to use to get this? Or do I add a FILE library? thanks

Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

Post by breiter on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Hi, supporting a text based storage format is on our roadmap, see https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html It will be an Add-On feature called "File Based Storage" for the professional developer edition. Structured text POUs will be stored as plain text. Other graphical languages will remain in an xml format. You will be able to switch the storage type for projects. Certain workflows will become easier this way. Nevertheless restrictions will remain because of CODESYS specific storage logic (for example how methods below function blocks are stored as file). So merging using our Git Integration Add-On remains the recommended workflow. A workflow involving Visual Studio Code as the main IDE is not supported. Simply because many topics like library management, task configuration or fieldbus configurators are not available for VS Code. A PLC project is a lot more than just some ST POUs. Best Regards

Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)
