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

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.

Hello, Is there a maximum number of Masters that can connect to a Modbus Slave that is configured in the device tree? Is this limited by the CODESYS IDE, or the manufactures hardware and CPU load? Thank you,

... you say 1.6 Nm is only enough torque to unscrew a loose bottle cap ... This the the value of torque: from 1,2 Nm to 1,4 Nm that is cosidered acceptable for an old people. 1,6 Nm the torque considered acceptable for general use caps.

This is still a huge problem. Does someone know how to update the frame references (not manually for every frame-element...)?

Post by i-campbell on Codesys 3.5 Library Download Failed ^{CODESYS Forge talk (Post)}
You use very old codesys, maybe SP13? the newer sp17 libraries are in a format not compatible with your version. I suggest upgrading everything to at least SP17, but may as well go to SP20 Patch 2.
