Post by damian177 on Problem with downloading OPC UA tags by Data Source Manager ^{CODESYS Forge talk (Post)}
Hi, In Codesys V3.5 SP20, using Data Source Manager I am trying to connect to the OPC UA server and receive tags from it. The connection is ok, but the Codesys have a problem with downloading Tags group. The window (downloadingTags.jpg in attachement) never stop. After waiting for a while, I disconnect the connection and only the Server group remains downloaded, with OPC UA server diagnostic data (and this is read in Codesys). Of course, I tried connected via another OPC UA client : UaExpert , and everything works as it should, all tags are downloaded (Uaexpert.jpg screen). Has anyone on the forum encountered the OPC UA client configuration in Codesys? Is it possible to manually request the appropriate tags from the OPC server for reading in Codesys?

Post by shabroz-gill on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
If i loose the network and the opcua data source suddenly looses connection with the server, i get an exception and my application stops working. I am using the latest version of the communication add v4.5.2.0 Is this a known issue? This makes the datasource unusable because it is inevitable that we will loose connectivity at some point, and the datasource crashing everything due to that seems to be a deal breaker. I can provide more details is someone from codesys is reading this. You can recreate is by just shutting off the Opc server after the codesys data source is connected and reading data from it. The codesys app does not crash everytime and sometimes it is able to reconnect without crashing, so you may have to try this a few times to see the exception. Best regards

Post by taqamert on CANopen PDO Issue with Pressure Sensor in Codesys ^{CODESYS Forge talk (Post)}
Hello everyone, I am using an IFM CR0303 model PLC, which has a tilt sensor and a pressure sensor connected via CANopen. Both sensors are from the same brand (ATEK). I can read data from the tilt sensor without any issues, but I am unable to read data from the pressure sensor. I have added the EDS file in the PLC configuration and adjusted the node-ID settings. When I check with the PCAN-View application, I can see that the selected PDOs are coming through, but the data is not reaching the Codesys side. What could be the issue, and what can I try to resolve it? Can anyone help me?

Why do you develop things like this? The workflow should be highly dependent on autocomplete, then if that's not super obvious browse to definition and everything is made clear possibly with the checking of a few types. The nature of how things are done makes me think these libraries aren't developed for general use and are actually internal or for partners. The example projects include objects that don't appear in autocomplete and then lead nowhere obvious when browsing. Do you consider developer workflow when creating these libraries? Are some libraries really for public use such as Visu Utils and others not? If so which? It's really hard to tell.

@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

Ciao damian177, provo a chiederti un'informazione. Sul mio progetto Codesys(ver.3.5 SP17) non è visibile l'oggetto "Data Source Manager". Il PC con il progetto Codesys(client) è collegato via rete TCP ad un PLC Siemens1200(server). Sul PC con Codesys ho installato UAexpert(client) e riesco a vedere le variabili del PLC1200. Riesci ad aiutarmi a capire come mai non è visibile l'oggetto "Data Source Manager"? Molte grazie

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
After some more digging I realized that I get an error on the PLC Logger saying PersistenceChannel: 150 (invalid type in data: SimpleLibrary). I suppose the issue could be found in the ConfigData, which is automatically generated and which looks like this: 1 9##83 SimpleLibrary#GVL.aMoreZeros.[1]#0#64512#15#0 <[2]#0#64520#15#0 <[3]#0#64528#15#0 <[4]#0#64536#15#0 <#0#64544#15#0 <[6]#0#64552#15#0 <<lrVar#0#64560#15#0 <strVar#0#64428#16#80 <uiDummy#0#64370#11#0 Perhaps the fact that the variable is stored within a library confused the compiler? I tried changing the PersistenceChannel parameters to xCompressTags := FALSE which changed the entry in the data file from _xCompressTags BOOL:TRUE _xCompressTags BOOL:FALSE but the actual content of the data file and also the config data did not change.

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Using SDO, I can read the EtherCAT mappings and offsets from various registers like 0x1c12, 0x1c13, etc. When I obtain registers mapped in the PDOs and various offsets, I could technically access directly to the statusword, controlword, etc., if they are mapped. I have noticed that on IoDrvEthercatLib.ETCSlave_Diag I can find pointers to the input and output buffers. However, although the input buffer can be easily read by referring to what has been obtained from the SDOs, it is not possible to write to the output buffer, as it is overwritten in each cycle by the data from the IOMapping task. Is there a way, knowing an instance of IoDrvEthercatLib.ETCSlave_Diag, to obtain the pointer to the first data in the IOMapping? The offsets are identical to those of the PDOs, but obviously the data is a copy. For me, the cleanest thing would be to access the pointers on IOMapping, for DS402a devices to retrieve the key data and point them to internal references. I need to know this as, having developed our own motion library, I would like to simplify the initial setup by eliminating unnecessary and nonsensical mappings that can lead users to unnecessary errors. In the current version that we have been using for years, we have to map everything manually. I would like to pass only the slave reference to the FB_init constructors and eliminate the mapping.

Post by paro on OPCUA array max length? ^{CODESYS Forge talk (Post)}
I think the amount of data is already relatively high and maybe it has something to do with that? Maybe also the CPU load of your device? an array with string(5000)? and have you tested with how many array elements it still works?
