Post by eguerra on Error in ScriptingEngine Docs - create_pou() ^{CODESYS Forge talk (Post)}
In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Post by scarter on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by timvh on Limiting Memory Access of an Array to Within its Bounds ^{CODESYS Forge talk (Post)}
Add the object "POU for Implicit Checks" to your application, then select "Bounds check". This will create a function which is automatically called each time an array is write accessed. In the function you can handle "out of bounds" situations. By default it will be limited to its lower or upper bound.

Post by fenicklar on Login problem with FileTransfer on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Hello everyone, I'm currently trying to set up a FileTransfer function from a Webvisu to my Raspberry Pi 5 on Codesys 3.5 SP 19 Patch 6. I went in the files CODESYSControl.cfg and CODESYSControl_User.cfg and added : [CmpWebServerHandlerV3] AllowFileTransferServices=1 And it seems to be working. However, I cannot access my several Webvisu without putting my login. That's a problem because one of my webvisu is in kiosk mode on the raspberry itself and there is nokeyboard attached, it's just an information screen, but I can't view it. Is there a wey to enable the File Transfer without requiring to login ? Thank you for your time

Post by c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ? Thanks in advance

Post by struccc on Problem Update new version Master ethercat ^{CODESYS Forge talk (Post)}
Hi, I had some issues as well migrating to the new version. What I have learnt: - Have to check all the libraries in the library manager, if they are the proper versions. - Some other parts of the application, maybe an old library referenced by another one can keep the old Ethercat libraries.... Use the "Placeholders" function on the library manager - See if there is a new version available of the slave "devices". Might just have to update them ... I had problems moving from 4.7 to with 4.8, especially with the 2nd adapter for redundancy - some devices failed to initialize properly.... So I have just downgraded those libraries now. P.

I guess you could archive the project, open the archive and go online. Is that suffiecient for your use case?

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]
