Post by liamb on Converting CANbus to Decimal from signed 2's complement CODESYS Forge talk (Post)
I need to combine two 8 bit CANbus messages to 16 bits signed int then convert to decimal Decimal from signed 2's complement. I've been using the below code to read for new messages, combine them then assign them to a variable What is the best way to do this for from signed 2's complement? fbRxMessage351(Data := RxMessage351Data); IF fbRxMessage351.NewMessage THEN ChargeVoltage := (WORD_TO_REAL((RxMessage351Data[0]) + ((RxMessage351Data[1]) * 256))) * 0.1; END_IF

Post by dogulas on OPC UA C# client connecting to OPC UA CODESYS server CODESYS Forge talk (Post)
Noob alert! I’m just getting my feet wet with CODESYS. I have a “Hello World” project in the CODESYS IDE. I’m using the Win SoftPLC on the same computer. I’ve added a Communication Manager under the Application node. Under that is “OPC UA Server -> IEC Symbol Publishing 01”. I also added “OPC_UA_Symbols -> Information Model”. I’m not sure I need the second thing. I was grasping at straws. I also set up several dummy symbols in the IEC Symbol Publishing 01 node. In my C# application, I am trying to get an instance of EndpointDescription from CoreClientUtils.SelectEndpoint(“opc.tcp://localhost:1217/Gateway-1”, useSecurity: false, 15000). I wasn’t sure about the “Gateway-1”. I found that in the CODESYS IDE under the project -> Communication Settings. When I execute the previous method call in C#, I get: “BadSecureChannelClosed”. I have no idea what that means. Any pointers to documentation are welcome.

Post by micik on ERR_OK not recognized CODESYS Forge talk (Post)
Hello, if I try to use ERR_Ok in my code to check whether the file is open correctly or not, I get an error "Identifier ERR_OK not recognized", I can use plain 0 (zero) instead. But in general, is this a proper way to check for success of file operation since the 4th parameter is a poinmter to RTS_IEC_RESULT, and normally I would expect this to be used somehow. _hFile := SysFileOpen(_sFileName, am:=SysFile.ACCESS_MODE.AM_WRITE, ADR(_result)); IF _result <> 0 THEN udDiag := 100; RETURN;

Post by micik on SysFileOpen not working CODESYS Forge talk (Post)
Hi, I have the same problem. Some of the libraries I created over time depend on writing files to a folders like c:\Temp. I can confirm that proposed solution is not working with 3.5.20 Patch 2. Can you please specify wich exactly .cfg file needs to be modified and in what way, in order to include c:\Temp in the SysFile path? Thank you!

Post by expertplas on No connection to opc server from codesys opc client CODESYS Forge talk (Post)
Hello, we have aproblen to connect our CODESYS OPC Client to the OPC Server. We installed the client according the CODESYS manual. We can browse the server and variables can be linked to the PLC. I created a self signed certificate for the CmpOPCUAClent as described. The server has a cerificate also. I copied the certificates to the trusted zone of server and client. But when it comes to data exchange we get an error message. "Communication error in data source OPC UA Library. Error ID : 7001 German : "Kommunikatinsfehler inder Datenquelle OPC UA -Bibiothek. Es wurde kein genauer Fehler angegeben. Fehler ID : 7001" It semms that there is no cerificate exchange. We are working with CODESYS 3.5 SP19 Patch 5. Can anyone here say something about this error or has an idea for a solution? Thanks.

Problem solved. The problem turned out to be the lack of access to the default location "Mounts", I changed it to /home/user1 and now it's ok.

Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

Post by abauza on Image Pool using in other libraries CODESYS Forge talk (Post)
Hi im Albert, im developing libraries for my PLCs and i have some issues on visualization part. First of all I have done a library that have a image pool with a list of 4 gifs "ImagePoolErrors" (i've tested in other projects and it works) but the problem comes when i create another library that in the visualization part contains images from my image pool library, when i simulate a program that includes a instance of my second library object the visualization images dont show, any of them, i've checked all the references and tried some options of the image properties but without any difference. Here is the screenshots of the first library (that contains Image Pool) and the second library (that includes images of the image pool first library) and the visualization simulation (with the missing image gif issue). Any idea of what i forgotten in the process? If you need any detail of the library or of the project or you need the library file, ask me, thank on advance

Post by c3po on Von SNMP auf IIoT wechseln CODESYS Forge talk (Post)
Hallo, 1. ich bin komplett NEU was Codesys angeht 2. ich muss direkt ein Retrofit machen von V2 auf V3 3. Neue Steuerung: WAGO 750-8211 PFC200. 4. das Projekt in V2 hat über SNMP daten im Netzwerk zur Verfügung gestellt, oder diese gelesen 5. das Projekt in V3 kann SNMP nur noch eingeschränkt nutzen, deswegen wurde mir vom WAGO Support nahegelegt die IIoT Lib zu verwenden. Frage: Wie mach ich das? Konkret: Ich habe die WagoAppSNMP Bibliothek installiert, damit kann ich schon mal Set und Get nutzen (hoffentlich, hab es ja noch nicht getestet, sondern nur programmiert). Ist das ein schlauer Weg, das über diese Lib zu machen? Denn: was macht der SNMP_SET_PLCDATA_WRITEAREA ? Den kann ich über die Wago Lib nicht nutzen und weiß auch nicht, was dieser Baustein konkret tut (Bild im Anhang). Es scheint mir, hier werden Daten auf ein Word im Netzwerk geschrieben? Aber geht das nicht auch einfacher? Es ist ja keine Adresse hinterlegt, wo das hin gehen soll oder? Also, ich verstehe den Baustein nicht so ganz und konnte bisher auch keine Erklärung dazu finden. Vielen Dank schon mal für eure Unterstützung, K.
