Post by sumit on Remote Ethernet/ip Adapter communication with scanner running on codesys ^{CODESYS Forge talk (Post)}
Hello there, I have my ethernet/ip adapter (from Texas Instrument) running on Texas Instrument Board and I have configured the scanner on codesys. I have mapped the I/Os and I can see (on wireshark) the frames coming from adapter but I don't see my input variables in scanner get updated, they just stay at 0. I wanted to see the real data that has been sent from adapter to scanner on codesys. I am not sure if the problem is in I/O mapping or there is a step/s that I have missed. I have attached the screenshot of my project for your ref. Thank you, Sumit

Post by hwillems on Ranges, Lambdas, on Fixed arrays of structs ^{CODESYS Forge talk (Post)}
I do datastructures and algorithms in Codesys. For example a Struct of Person with thing's like IdNumber, Name, Age etc. as example. Now i do all kind of calculations, filters. So i have this pretty big Fixed Array with Structs. On this struct i want to do simple stuff you can do easily in C++/Python/Rust etc. For example i want to do this: AvererageAge := Average(Peoples.Age); Then it will return the average of all members ages. Or Sort struct on age etc. Or sort on alphabetical Name. Or use Lambda functions to filter/mutate out things like, filter out everybody above 18 years old. Or remove people who it's name start with "A". Currently i have to write my own custom function for example sorting on Age. And make a super specific function based on that particulare datastructure. Here an Example: (*Before calling this FIlter method, set the mNodeFilterSwitch to the desired filter.*) CASE mNodeFilterSelect OF (********************************[ Status Filters ]***********************************) NodeID: FOR x := ACS_OUT_BEGIN TO ACS_OUT_END BY 1 DO FOR y := ACS_IN_BEGIN TO ACS_IN_END BY 1 DO IF marrNode[y].Status.oiNodeID > marrNode[y + 1].Status.oiNodeID THEN mNodeTemp := marrNode[y + 1]; marrNode[y + 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; Started: FOR x := DES_OUT_BEGIN TO DES_OUT_END BY -1 DO FOR y := DES_IN_BEGIN TO DES_IN_END BY -1 DO IF marrNode[y].Status.oxStarted > marrNode[y - 1].Status.oxStarted THEN mNodeTemp := marrNode[y - 1]; marrNode[y - 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; Starting: FOR x := DES_OUT_BEGIN TO DES_OUT_END BY -1 DO FOR y := DES_IN_BEGIN TO DES_IN_END BY -1 DO IF marrNode[y].Status.oxStarting > marrNode[y - 1].Status.oxStarting THEN mNodeTemp := marrNode[y - 1]; marrNode[y - 1] := marrNode[y]; marrNode[y] := mNodeTemp; END_IF; END_FOR; END_FOR; END_CASE; I have like 30+ of these in the enum. Not really DRY code right? These are custom made bubble sort filters in a function. You pass in the Datastructure, and say what function you want. (This is an enum collection of sorting functions) And then the Array with Nodes of Structs gets ordered. Why can't we have Iterators and Lambda's and build in standard functions like regular languages? Also i use bubble sort because it's the easiest to implement because i can't get this to code DRY. Problem with ST (Even the new one with classes) that it's very limited for programming datastructures and algorithms. Yes you still not want dynamic memory and you need to choose the correct algorithm so you know the most extreme edge cases regarding the time it takes to execute the algorithms.(Real-time execution) How are other people dealing with this? Here for example saw some software using an adjusted ST language and having FOR EACH possibility: https://www.fernhillsoftware.com/help/iec-61131/structured-text/st-for-each.html You can then build your own custom Iterator functions. I wish the IEC 61131-3 standard would be more expressive and having more standard modern features, but still keep close to the fact of no dynamics memory and real-time systems.

Post by k2saki on CNC / G-Code streaming processing ( to start quickly in long G-Code File ) ^{CODESYS Forge talk (Post)}
Is it possible like G-Code streaming processing (like FANUC or SIEMENS DNC Function )? Or Does anyone know the tips for CODESYS Motion to start moving long Long G-Code File quickly? I have to wait long time after "Start" button to start moving, I have to wait finishing interpreting whole G-Code file, ( and I have to prepare huge buffer to store. ) Now, I'm working on my CNC Project using SMC_ReadNCFile2, and SMC_NcInterpreter to preprocess G-Code. I tried to set SMC_Interpolator.xExecute to true to Start while after SMC_NcInterpreter processed more 50-line of G-Code, but that not worked, I had to wait SMC_NcInterpreter processed all lines to start SMC_Interpolator. G-Code have about 2000 lines of XY of G01 (or more over.. ) of short segment that a CAM software has exploded from NURBS Curve.

Post by vformanek on OPCUA Datasource, can not login... ^{CODESYS Forge talk (Post)}
Hello? I have a problem with datasource... I am trying to connect to a OPCUA server. I create a datasource, but I can not login into it. I need to use login credentials to login... Everything works fine in UAExpert, but in codesys I cant seem to get in properly using the login credentials... I have tried to configure the datasource initializer but seem to keep failing... Do I need to call it somewhere ? Will the find endpoints work with this configured to store my password ? !

You have to update the device in your IDE to 3.5.14 or you can contact your Codesys runtime supplier to know how to set the connected system to 3.5.19

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
Solved it! The simple answer was to declare a variable as POINTER TO STRING and assign the GetMessage result to that variable. Then, the ^ operator can be used to extract the message as string.

you try to convert a WORD with BYTE_TO_HEX directly? Using https://de.helpme-codesys.com/ lead to the SM3_shared lib. There is a function: https://content.helpme-codesys.com/en/libs/SM3_Shared/Current/SM3_Shared/StringFormat/Word_To_HexString.html

You need to start the application, see the "start" option at the top left (next to close simulation).
