Post by berebri on TLS Verschlüsselung mit MQTT - Validate CA ^{CODESYS Forge talk (Post)}
Sorry - I should have posted this in the German-Froum... Hallo zusammen, ich bin dabei mit MQTT_Client_SL eine verschlüsselte Verbindung zu einem MQTT-Broker (mosquitto) aufzubauen. Das funktioniert auch. Jetzt möchte ich das Zertifikat vom Broker verifizieren, ähnlich wie das auch bei dem Programm "MQTT Explorer" möglich ist (dort funktioniert es). D.h. ich möchte das über das Zertifikat der CA verifizieren, dass ich mit dem Client verbunden bin. Kann mir da jemand Hilfe geben was ich dazu machen muss? Ich vermute mal, dass ich dazu NBS.TLSContext verwenden muss und habe dazu auch einiges gelesen, konnte es aber bei mir nicht ans Laufen bringen. Wie bringe ich dem Client bei, über NBS.TLSContext das richtige CA-Zertifikat für die Verifikation zu verwenden? Kann mir da jemand bitte helfen? Dankeschön :-)

You get an array of DWORD into your receive buffer. You need to process this into usable data, before you can fit it into your DUT. I've made it work using FbWrite_ToIEC_ByRule in stead of Fb_JSON_ParseAndModify. I've attached images of the code. You receive the data into ARRAY[0..1023] OF DWORD. Then you use that array as the input for fbWrite_ToIEC_ByRule. To get the output from this you define a rule to fit the expected data structure including nesting levels. The you feed the rule into FbWrite_ToIEC_ByRule and then you can set the output to be of your DUT type.

Post by berkdan on SMC_ReadNCFile2 is always busy ^{CODESYS Forge talk (Post)}
Hello, I’m using CODESYS V3.5 SP18. When I try to use SMC_ReadNCFile2 to read the file /PlcLogic/gcode.nc, the function block's bBusy output remains TRUE indefinitely. Can you help me understand what I might be doing wrong? Here is how I’m calling the function block. The value of strFileName is 'gcode.nc'. fbReadFile( bExecute := bExecute, sFileName := strFileName, bAbort := bCycleStop, fDefaultVel := RetainVariables.xSlowVelocity, fDefaultAccel := RetainVariables.xAcc, fDefaultDecel := RetainVariables.xDec, b3DMode := TRUE, bParenthesesAsComments := TRUE, fDefaultVelFF := RetainVariables.xFastVelocity, fDefaultAccelFF := RetainVariables.xAcc, fDefaultDecelFF := RetainVariables.xDec, ErrorID => gCNC.eErrorId, errorPos => gCNC.eErrorPos, ErrorProgramName => gCNC.eErrorProgName, bBusy => bReadFileBusy, sentences => sentencesss ); Thanks in advance for your help.

Hi, do you process the sentences subsequently? If not, the function block fills the sentences (queue) and waits for the sentences to be processed, so that new sentences can be read and filled to the queue.

Post by dkugler on CoDeSys V3.5.19.7 Code erzeugen dauert extrem lange ^{CODESYS Forge talk (Post)}
Ich hatte einige Jahre Codesys in einer VM laufen. Das habe ich vor allem wegen den sehr langen Compilierungs- und "Projekt speichern"-Zeiten wieder aufgegeben. Mein Hauptprojekt hat eine Größe von 14MB, erzeugter Code ist bei 20MB und enthält über 50 Visualisierungsseiten. Bei mir dauert das Code erzeugen mit SP20 P4 ca. 1 Minute. Mein Laptop ist ein i7 3.1GHz 16BG RAM und 5-6 Jahre alt, also wahrlich keine Rennmaschine. Ich denke dass die Übersetzungszeit extrem vom Projekt, den notwendigen Bibliotheken, Virenscanner(temporär abschalten, besser? schlechter? gleich?), gleichzeitig laufende Windows-Programme etc. abhängt. Ich schließe generell während dem Programmieren alle anderen nicht absolut notwendigen Anwendungen, um Codesys den Zugriff auf möglichst viel RAM und CPU-Leistung zu ermöglichen. Viel Erfolg bei der Suche nach dem Flaschenhals!

Hey tk96 Thank you for your help. I have found the reason why fbreader stuck. It was not the program but it was the gcode itself. G21 command blocks the reader. And multiple G codes in a line also blocks the reader. My code was: N010 G21 G17 G90 -> Blocked the reader When i change it to: N010 G90 N020 G17 Then it worked. The only thing i did not get is why the reader did not thwor error. ErrorId was SMC_NO_ERROR. Anyway, it is now working. Thanks again.

Hi, the subsequent interpreter should report an error? The reader is just reading the file without checking the syntax.

Post by zoppp on Visu Frame-configuration___text will not work ^{CODESYS Forge talk (Post)}
Yup, I've been having the exact same issue. A workaround that was working until Visu 4.8.0.0 was using TextList as the type in the frame configuration and then wrapping the text in quotes when configuring it. Im not sure if it will work with variables and I know it does not work if the type is text.

Post by hclai on Maximum Array Index Issue ^{CODESYS Forge talk (Post)}
I was trying to use a table object in visualization. I want to dynamically show the valid rows in the table. However, it does not work when there is 1 row. i put the maximum array index to 1. it does not show the 1st row. when i change to 2, it show the second row only. my project with older visualization profile version is working perfectly fine. I did some test and realized that i must use a Row Selection variable to change from 0 to 1. With this change of Row selection, then the row 1 will show up.
