I'm having the same issue.I think it may be something related to the device adress that changes depending on the network i'm using, but now i don't have access to the one i used while setting my user. Did you find any solution for this?

your device in the device tree is Pi 64 online you have Pi MC (32bit) - update device in the device tree to Pi MC then it will work.

Post by mp9876 on Problem using MeasureFrequence FB ^{CODESYS Forge talk (Post)}
Hi everyone, new at Codesys and PLC programming in general. I am using Codesys Win V3.5 SP20 I would like to measure an encoder's frequency output (obtaining that pulse train from Factory IO) and intended to use the MeasureFrequence FB (Intern/CAA/Utilities/CAA Mathematics/3.5.19.0). As mentioned in the title what I need to measure is low frequency, such as lower than 40hz (a cycle every 25mS) or so; I could even go lower frequency if required as this is for test purposes) therefore I am not expecting problem measuring a low frequency with that FB The library in question appears to be installed as I can retrieve it from the Library Repository. I can also see it from the Device's Library Manager. Problem arises when I am trying to instantiate this particular FB. I go like this: VAR MeasF:MeasureFrequence; END_VAR Please note that as soon as I start typing the "MeasureFrequence", the MeasureFrequence comes out as a viable option in auto-typing; seems to indicate that the FB is recognized somehow. But there is no way I can compile this as it comes back with the following: C0046: Identifier 'MeasureFrequence' not defined. Tried to rename that to ABC instead of MeasF; same issue. Possibly that the library is not properly installed ? Placeholder ? I would greatly appreciate a bit of guidance if possible. Thank you and regards, Mike

D.OUT: 5000 -> 2214 ->662 -> -888; X = ACTUAL= -100; SET_POINT = 0; Error = 100; D.OUT = 5000 = 100 / 0.02; Y = 0.1*(100 + 0.04 * 5000) = 30; X = ACTUAL= -70; Error = 70; D.OUT = (30-70)/0.02 <=> -1500;???? How to explain this?

I will use Codesys to program a PLC. I will connect the PLC to the computer via the CAN interface using PEAK CAN, but Codesys does not recognize the CAN adapter. I have added the following libraries. What should I do? What steps should I follow?

Well still similar questions remain. I don't know of "CmpRecoverySwitch" and the only thing google has to offer is your xml file. I think you'd need to provide a lot more info before anyone makes much effort here.

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
So I found the mistakes. First I forget to deactivate "Use access rights defined in the user management". And also I used in "UaModeler" a project name with whitespaces, which lead to a wrong namespace name.

You can use the R_TRIG and F_TRIG function blocks to generate a pulse in Rising or Falling edge of your signal. Have a look here: https://content.helpme-codesys.com/en/libs/Standard/Current/Trigger/R_TRIG.html

Post by berto on Opening PDF in Web Browser in Target Visu HMI ^{CODESYS Forge talk (Post)}
Hi everybody, I've been facing problems with the PDF visualization in Web Browser. I am trying to open a pdf file called 'sample.pdf' which I manually saved inside PlcLogic/visu folder. I am setting the web browser URL as: 'http://127.0.0.1:8080/sample.pdf' but I get 'refused connection'. I got a similar error trying to open https sites and I discovered that I can only open http websites. Opening 'http://de.wikipedia.org' everything works fine. I also tried to check using code whether the sample.pdf is present in the directory. Unfortunately, when I try to read directories of 'PlcLogic' I get file FILE_OPERATION_DENIED (I am using File.DirList). I would like to be able to open PDF files in web browser. Possibly to move new PDF files in the folder as my customer wants to display different pdf manuals on the hmi. Here you find some screenshots and my .project. I am using Codesys 3.5.19.70. Best regards, Berto

Post by drml on Array to String ^{CODESYS Forge talk (Post)}
If a size is not specified, CODESYS allocates 80 characters by default for a string. After 7 seconds, does your Json_string contain all of your 20000 key/values? Or is the result truncated to 80 characters?

That is an output of the Function Block ModbusMasterRTU example: xIsConnected=> xIsConnected In this line the VAR ModbusMasterRTU.xIsConnected is written to VAR xIsConnected xError=> is writing to nothing here.

Post by tk096 on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, dwIpoTime should be set to the cycle time of your motion task. It defines the interpolation interval of the interpolator. E.g. in the attached screenshot, the task has a task interval of 4ms. The dwIpoTime input of the interpolator should be set to 4000.

Post by trusty-squire on CNC - How to manipulate SMC_GeoInfo objects ^{CODESYS Forge talk (Post)}
I have an application using CNC GCode interpolation, but I need to modify the GCode provided to the PLC based on certain parameters. I am currently attempting to modify the SMC_GeoInfo objects in the SMC_OutQueue using the code below. Note that all the other code is pretty standard and works fine, but when I add the below it errors. PROGRAM TEST VAR fbReadCncFile : SMC_ReadNCFile2; fbCncInterpreter : SMC_NCInterpreter; arrCncInterpreter : ARRAY[1..99] OF SMC_GeoInfo; pGeoInfo: POINTER TO SMC_GeoInfo; giGeoInfo: SMC_GeoInfo; // ... END_VAR // ... Some code here in order to read CNC file using SMC_ReadNCFile2 and provide to SMC_NCInterpreter pGeoInfo := SMC_GetObj(poq:=ADR(fbCncInterpreter.poqDataOut), n:=1); IF pGeoInfo <> 0 THEN giGeoInfo := pGeoInfo^; // Do some manipulation here, then update the queue at the same position MC_SetObj(poq:=ADR(fbCncInterpreter.poqDataOut) , n:=0 , pgi:=ADR(giGeoInfo) ); END_IF It throws an error when I get to the line giGeoInfo := pGeoInfo^; Error: EXCEPTION [AccessViolation] occured: App=[Sim.Device.Application], Task=[PathTask] How do I use SMC_GetObj and access the data? It creates a pointer with the value as shown in the photo, but all the dereferenced values say dereference of invalid pointer.

Well I created a user as Admin, gave access rigths to the file but still can't read the files in the plc it gives the same error. I guess is something to do with plc itself.
