Post by installwhat on raspistepper error after install ^{CODESYS Forge talk (Post)}
I've had issues getting the raspistepper installed, all due to errors upon installation. The closest I get is the pictured error. The functions are in the sm3_shared library. I can add this library but that leaves 2 issues. I don't actually know, and I really want to understand this, why the required dependencies haven't been installed correctly. If I add the library it's only available with through the namespace. What can I do to both understand and resolve this? Thanks edit codesys 64 3.5.20.0 - same error on other versions too sm3 raspi stepper 0.0.0.5

Post by timvh on Codesys SVN ^{CODESYS Forge talk (Post)}
If you use 3.5 SP10, then Git is not supported. SVN will work fine, but with this version you do need a USB key, because software licenses are not supported with this version. Off course you can work without SVN (or Git), but especially if you work with multiple developers on one project, it will save you a lot of time and you can keep track of all changes and improvements much easier. So how much is this worth to you?

Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

Post by ndzied2 on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
This is a consequence of how computers store floating point numbers. 0.1 cannot be exactly represented in a computer. This is not a CoDeSys thing. Here is a link to a converter to show you the exact value that is represented when you use a REAL data type (which is a 32 bit float). https://baseconvert.com/ieee-754-floating-point If you really need to keep track of 0.1 increments. use INT OR DINT and then add 1 each time and assume that there is one decimal place.

Hello, I have a counter that increments an INT value once per minute I want to display this value in Minutes until 60, then Hours/Minutes thereafter on the HMI Codesys V3.5 SP16 I can divide the minutes by 60 to get hours, but then the minutes is still more than 60. Example: a process has run for 350 Minutes. I need to display "5 Hours 50 Minutes" But if it's only been 45 Minutes, I don't want "0 Hours 45 Minutes" , just "45 Minutes"

Post by paro on "You are using inconsistent overlay settings, please check your compiler defines for the current application" error ^{CODESYS Forge talk (Post)}
Disable the setting "Support client animations and overlay of native elements" in the Visu Manager. Activating this setting should also set a compiler define (GENERATE_OVERLAY_VISU). Maybe the compiler define is set and the feature is not activated in the visu manager or or the other way round.. rightclick the Application -> Properties -> Build https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_properties_build.html

Hallo, und vielen Dank für die Antwort. Ich habe 'Modbus_Slave_COM_Port' in eine Watchliste genommen. Leider reichen meine Kenntnisse nicht aus, um aus dem Ergebnis irgendwelche Schlüsse zu ziehen. xBusy und xError wechseln zwischen true und false (im Gegentakt), der angezeigte Fehler ist 'Response Timeout'. iChannelIndex wechselt zwischen 0 und -1. Wenn ich das richtig verstehe bedeutet das wohl, das der Servotreiber auf Anfragen einfach nicht reagiert. Ich hänge einen screenshot vom Watchfenster an, vielleicht kann jemand mehr herauslesen als ich. Nochmal danke fürs Lesen und Überlegen!

Hello, I’m looking for the ecoPlus21 development environment used with early IFM controllers (e.g., CR0020_Q firmware). We have an old project created in ecoPlus21 that cannot be opened in CoDeSys 2.3, and IFM no longer provides this software. If anyone still has the ecoPlus21 installer or knows where it can be downloaded, please let me know. It’s needed only for recovery and migration of an existing project. Thanks in advance,

Hi Manuknecht, Did you manage to solve the problem? I’m facing the same issue with Windows RTE SoftMotion — it works fine as long as nothing else is open in Windows, but as soon as I start another application, the EtherCAT DC time and max jitter values spike, and then all axes stop. I’ve already sent a support request to CODESYS, but haven’t received a response yet.

Post by kenth1973 on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
My MC_Phasing FB was stuck in iPhasingState=1 and error output HIGH on one axis. I could manually overwrite the state to 0 in the instance data. During normal run I see the state change from 0 to 10 to 100 back to 0 (maybe more states that I couldnt catch with the naked eye) But - what are the states numbers and their different explenations? This is not explained in the FB guide on codesys. (the pictures show state = 0 after I reset)
