Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

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 r-niedermayer on C0564 Warning Message ^{CODESYS Forge talk (Post)}
Please see or Online Help on how to initialize variable before using them: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Regarding the Attribute global_init_slot: You can use this pragma to influence the order in which signatures are processed during global initialization. It can only be applied to signatures. By default, the initialization sequence for variables from global variable lists is undefined! However, if, for example, variables from one list depend on variables from another list, it is necessary to initialize one before the other. (Aee OLH and Syntax) The placeholder <slot> must be replaced by an integer value that defines the position in the initialization sequence.</slot> The default value is 50000. A lower value causes an earlier initialization! If several signatures have the same value for the 'global_init_slot' attribute, the order of their initialization remains undefined! Cautious application should therefore be considered! Example: The project contains f.e. two global variable lists GVL_1 and GVL_2. The global variable "A" is part of the global variable list GVL_1: {attribute 'global_init_slot' := '300'} VAR_GLOBAL A : INT:=1000; END_VAR The initialization values of the variables "B" and "C" of GVL_2 are dependent on the variable "A". {attribute 'global_init_slot' := '350'} VAR_GLOBAL B : INT:=A+1; C : INT:=A-1; END_VAR So if you set the 'global_init_slot' attribute of the global variable list GVL_1 to 300, i.e. to the lowest initialization value in the example, then it is ensured that the expression "A+1" is well-defined at the time of initialization of "B".

Post by mrtt on Nach Neuinstallation Plug-In Fehler ^{CODESYS Forge talk (Post)}
https://forge.codesys.com/forge/talk/Engineering/thread/3d0a6d3317/ Hallo, ich wollte mich etwas in Codesys einarbeiten für zukünftige Projekte. Aber ich scheitere schon an der Installation auf zwei PCs (Win10 / Win11). Problem wie im oberen Link, an beiden PCs, aber unterschiedliche Plug-Ins. Laut Installer sind die Pakete aber Installiert, wenn ich sie Deinstalliere kommen andere Meldungen :D... 3.5 19 habe ich auf Win 10 irgendwann immerhin mal zum Starten bekommen. Wenn ich dann an die Pakete mit den Paketmanager gehe, bekomme ich aber während der Installation auch immer die Fehlermeldung. Was kann da los sein? Ich versuche heute noch einen 3. PC, aber irgendwie ist das ja nicht die Lösung :(. Vor allem das es immer andere Plugins sind zwischen 3.5 19/21 und Win10/11. Also da ist irgendwie keine Richtung drin :(. Kann mir aber nicht vorstellen das dass die Regel ist, sondern ich vermute das ich da was falsch mache. Oder eine andere Abhängigkeit / Installation etwas zerschießt... Grüße Malte edit: auf einem frischen Win11 gehts, was ist mi Codesys da nicht in ordnung? edit2: Ok ich habe alles was mit C++ und Runtime war vorher Deinstalliert. Nach der Installation musste ich aber immer noch Plug-Ins korrigieren. Dann ist Codesys gestartet aber eingefroren. Geholfen hat dann noch das deinstalliere von CodeMaster.

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Hi Everyone, For a fast monitoring system I am using Ethercat oversampling and timestamping inputs. As the customers has a lot of different configurations out in the field, we went for a dynamic Ethercat configuration. Already got the whole detection chain working but now I am stuck since two days in debugging the configuration. Here are my quesitons: I extended the dynamic config example for the EL3632 16#0E303052: //EL3632 pSlave^.SetDCSettings(TRUE,TRUE,80,80,TRUE,4000,0,0); pSlave^.AddSyncManager(16#1000,128,16#26,TRUE,3); pSlave^.AddSyncManager(16#1080,128,16#22,TRUE,2); pSlave^.AddSyncManager(16#1100,0,16#4,TRUE,1); pSlave^.AddSyncManager(16#1110,214,16#20,TRUE,0); pSlave^.AddFMMU(0,214,0,7,16#1110,0,1,1); pSlave^.AddFMMU(0,1,0,0,16#80D,0,1,1); xKnown := TRUE; This leads to a PLL Error for these devices. I double and triple checked the configuraton, but cannot find the issue. There seems to be one difference: the config dialog creates a startup parameter: 16#10F3:16#05, Name: Command_0, Value:0. Bitlen: 16, Stop on fault: false, jumpt at fault: false: next line: 0 a) I do not find information on how to set this in my code. Can you help me there? b) Without trying to set the value, I get a PLL error for these devices in the master log. Is the config wrong? c) Do I need to set the Master to Autoconfigure or Manual? I used autoconfigure for my tests. The stack creates input data addresses for the slaves input data range (pSlaves[i].InputData) which are different from those created when I use the Engineering tools dialogs to configure Ethercat. Specifically, the addresses seem to be aligned at 16 byte boundaries when they are created using the engineering tool, but may appear at uneven addresses when I use the script in dynamic config. I did not try to access ULINT at uneven addresses yet, but I am suspecting this may be a problem. Do I need to manually align the addresses ? Any help is appreciated...
