Post by struccc on Bibliothek: floatingpointutils ^{CODESYS Forge talk (Post)}
The issue s the byte order typically in this case. Can be especially problematic with floating point numbers - even more tricky if transferred with a word based protocol. It is a peasant way to try out the alternatives, dword order can be a-b-c-d, b-a-d-c, c-d-a-b, d-c-b-a where a is the most significant, d is the least significant byte. So all you need is to swap the bytes in your dword, until you get the expected result. If you don't want to mess writing code for this, I'd recommend CAA_Memory library for that: MEM.ReverseBYTEsInDWORD and MEM.ReverseWORDsInDWORD functions would definitively do the trick. Otherwise, can do like this: VAR dwIn : DWORD := 16#11223344; dwOut : DWORD; rOut : REAL; pIN : POINTER TO BYTE; pOUT : POINTER TO BYTE; END_VAR pIN := ADR(dwIn); //pOUt := ADR(dwOut); pOUt := ADR(rOut); pOut[0] := pIN[3]; pOut[1] := pIN[2]; pOut[2] := pIN[1]; pOut[3] := pIN[0]; Ugly, but does the job...

Post by micik on Start Codesys project and then execute python script from command line ^{CODESYS Forge talk (Post)}
Hello, by searching the forum, I have found an example of batch script that can be used to start codesys projct by temporarily setting env variables. However, I'm not sure how to modify this to start Codesys 3.5.20 and whether or not I need to specify "profile" with Codesys version at all. @echo off SET PROJECT=D:\TestScripts\Data\OnlineTest.project SET VARIABLES=POU.testint,POU.testoutput start /wait CoDeSys.exe --profile="CoDeSys V3.4 SP3" --noUI --runscript="D:\TestScripts\Forum_Environment.py" I have tried the following just to open the test project: SET PROJECT=C:\TEST\Example.project start CODESYS.exe --profile="CODESYS V3.5 SP20 Patch 2" But I'm not sure how to specify this project to be open after py script is executed. The py script should first add required library to the project and then project should be open.

there is a new problem with latest bootloader version. The problem seems to be: Version from2024-04-20 does not work-> 2024-01-15 version works the workaround is a rollback to January version: cp /lib/firmware/raspberrypi/bootloader-2712/stable/pieeprom-2024-01-15.bin ./pieeprom.bin rpi-eeprom-config pieeprom.bin > bootconf.txt rpi-eeprom-config --out pieeprom-new.bin --config bootconf.txt pieeprom.bin sudo rpi-eeprom-update -d -f ./pieeprom-new.bin sudo reboot

also, wenn du noch lscpu output posten konntest, wäre das super genauso angaben über die im detail verwende pi-hw-version. das logfile sagt keine nennenswerten fehler. der logger ist wohl aber auch nicht voll aufgedreht. auch könntest du codesys via console starten im debug-mode hoerzu ins opt/codesys/bin berzeichniss wechseln und dann ./codesyscontrol -d dann spuckt codesys (weil ohne configfile gestartet, alle ausgaben in der shell. spätesrens hier sollte die ursache zu sehen sein. die 30 sekunden ohne logfile deuten darauf hin, das die runtime meint nicht auf der zielplattform installiert zu sein

Post by bahrt on Mapping GPIO and adding GPIO configurations ^{CODESYS Forge talk (Post)}
Hi I am about to configure ALL GPIOs on a Raspberry Pi 3 model B V1.2. It seems that I have limited understanding of why not all the IO’s become available with the corresponding mapped IO’s – the 'dwInUse' contains mapping of the inputs from GPIO0 to GPIO27. But 'dwInputs' are only showing GPIO0 to GPIO8 and GPIO15 as available inputs. These mentioned inputs work fine You will be able to watch the limited mapped IO activity here: https://drive.google.com/file/d/1zz4PBNBfRZBF2YkiJ2VQxw6L9MBVji7R/view?usp=sharing Can you please bring your best idea on why GPIO09 to GPIO14 and GPIO16 to GPIO27 state are zero in the dwInputs register? Thanks in advance. Best regards Andreas Bahrt

Post by fpawlak on KNX SL on stock PFC200 firmware ^{CODESYS Forge talk (Post)}
Hi All. Is it possible to use CODESYS KNX SL on stock Wago firmware (Codesys version, not e!Cockpit). I have Wago 750-8212 with firmware 0.4.04.03(26). When I tried to run 'KNX SL' or even 'Device Reader', I have got [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE3' [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE2' [FATAL ERROR] Unresolved reference: 'CODEMGETCONTENTBYFIRMCODE2' What probbalby means that there is no running CodeMeter component on PLC. I have checked /etc/codesys3.d/CODESYSControl.cfg [CmpWebServer] WebServerPortNr=58080 [CmpSecureChannel] CertificateHash=86ccf31839a098ee32067179e26600f1bd6b36f8 [CmpUserMgr] AsymmetricAuthKey=a9d38381e75bbf1bbfc8749e97f536f68238a2ce So the question is if I can somehow add Codemeter to stock firmware? Or should I switched to CODDESYS Control for PFC200 SL or application-base runtime licence?

Post by levih on DocScripting ^{CODESYS Forge talk (Post)}
Hello I'm trying to use the DocScripting collection in Codesys. I've made it work on one PC(1) for the 3.5.16.4 version of the script collection. But when I try the same setup on another PC(2), I get an error message: Error loading Python DLL: D:\SCRIPTING\3.5.16.40\python27.dll (error code 14001) My setup on both PC's is thus: 1. Downloaded and installed Python 2. Copied the folder with the scripting collection to C: (because of admin rights) 3. Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4. I also can't seem to find any scripting collections on newer versions of Codesys? (e.g. 3.5.19.10) Thanks in advance!

Post by greenwood on CODESYS Control Raspberry Pi mit Servotreiber T6 von StepperOnline ^{CODESYS Forge talk (Post)}
Hallo, Ich scheine den Grund gefunden zu haben, das Kabel mit dem RJ45 Stecker ist für RS232 verdrahtet (am anderen Ende des Kabels ist ein 9-poliger SUB-D Stecker, nicht wie von mir im Eingangspost behauptet ein USB Stecker). In der Anleitung des Treibers ist immer nur von RS 485 die Rede. Alerdings habe ich es gestern abend noch geschafft eine funktionierende Version der setup-software herunterzuladen, und die verbindet sich offenbar über RS232. Daraufhin habe ich mir in der Anleitung des Treibers das Pinout der RJ45 Buchse nochmal angesehen, und die hat Kontakte für RS232 und für RS485. (Die liegen jeweils ganz am Rand, so ist mir das vorher nicht aufgefallen). Ich muss also als Nächstes ein richtig verdrahtetes Kabel auftreiben, und dann sehen ob das mit dem Adapter den ich habe funktioniert. An einen Abschlusswiderstand habe ich auch schon gedacht, nur weiss ich nicht wo ich den an einem RJ45 Stecker / Buchse - Paar anbringen soll... Ich bitte um Entschuldigung für die Verwirrung, ich mache das alles zum ersten Mal und es ist ganz schön viel auf einmal für mich. Nochmal vielen Dank für die Unterstützung!

Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>
