Post by jmfernandes on OpenDir always in error ^{CODESYS Forge talk (Post)}
Hello I'm trying to use DirOpen to access a directory where then I can read/list the files inside. But I can't list any files because DirOpen.xError is always true. In eError the message is this: " ERROR_UNKNOWN Local library error ID (0: no error; 5101: time out)**** " I have in the file explorer the path 'C:\CodesysTest\Aluminium' and to make sure I also created in the plc a folder to 'prj/Recipes/Aluminium'. I tried using the different paths, but in both it happens the same thing.Inside the folder Aluminium there is two csv files, that I want to list. I added in the library manager CAA Files and CAA Types. I am using the example of https://content.helpme-codesys.com/en/libs/CAA%20File/Current/Examples.html#directory but not matter what I do, I can't get the list the names of the files. What am I missing?

A standard string is actually a list of bytes that represent the ASCII code for each character. The following part of code will give you the ASCII code of one of the characters in the string: byChar := sInput[i];

Post by e60newbie on Alarmtabelle Historie ^{CODESYS Forge talk (Post)}
Hallo Forumsgemeinde, ich stehe vor einem Problemchen wo ich keine Lösung finde. Folgendes: wir haben ein HMI an einer Mobilen Arbeitsmaschine wo sämtliche Fehler in der SPS (nicht im HMI) resettiert werden und im HMI alle als "REP" definiert sind, also selbstresetierend wenn das "Auslösesignal" entfernt wird. Soweit so gut. Nun wenn der Kunde die Maschine mit einem Aktiven Alarm ausschaltet, auch das HMI, bleiben die Fehler in der Historie als aktiv hinterlegt. Es gibt hierzu keine möglichkeit diese zu Quittieren? Sieht eben etwas unschön aus wenn da Fehler als aktiv anzgezeigt werden die uralt sind.

Post by simotion on Pointer to Softmotion axis ^{CODESYS Forge talk (Post)}
In my projet I use Softmotion. There are several Softmotion axis (type SM_Drive_Virtual). In the Global Variable List I have an array of pointers to the adress of the Axis. Axis : ARRAY[1..iMaxCntAxes] OF POINTER TO AXIS_REF_SM3 := ADR(AX01_Axis), // [1 ADR(AX02_Axis), // [2] This works, but when compiling I get the message : . [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX01_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX02_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. Is there a way when initializing to force the hardware (softmotion axis) to first initialize and then the Global Variable List?

Post by askjong on Update variables when OPC UA Client updates. Error ID: 268468277 BadAttributeIdInvalid ^{CODESYS Forge talk (Post)}
Hi, I'm connecting to a OPC UA Server using the Data Soruce Manager OPC UA Client. This works well until the OPC UA Server updates and the OPC UA list doesn't match up when i did last clicked the "Update variables" to add variables. All the variables are still the exists and none are removed from the server, but more are added during the engineering process. The error message i get in CODESYS is "Error in OPC UA call BadAttributeIdInvalid, Error ID: 268468277". The issues is fixed when i press the "Update variables" button and just press ok without adding or removing any variables in the list. Is there a way to either automatically update the browsepath if it fails or on startup, or to trigger it by code?

Post by jari-koivuluoma on Newly created texlists wont appear in the selection dropdown ^{CODESYS Forge talk (Post)}
When I create a new textlist in Codesys 3.5 SP19 Patch 5, it wont appear in the dropdown menu at Rectangle element > Dynamic texts > Text list. If I just type the name of the textlist to the field (in quotes), I get an error saying that some file is missing. Any good ideas what to do and what is going on. I recently updated to that version and I only now noticed this when I needed to add a new textlist so Im quite screwed with this not being able to add text lists. While im typing this, I tried copying an existing list and modifying it and it seems to show. Any ideas?

Post by snhatton on Retain memory change to ZERO ^{CODESYS Forge talk (Post)}
I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
The individual structures were declared in a separate global variable list on a trial basis. But even this did not change the behavior. A total of 1667 variables are processed in a recipe. A reduction (e.g. saving only the first three drive parameter sets) also brought no change.

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".

It should come by default on a normal install of Codesys 2.3, but it's a bit hidden: Like for any other library, go to Resources > library Manager > Right click on list of libraries > Additional library. On the browser that opens, instead of looking in the default folder, use the dropdown menu at the bottom to change the folder (SysLibMem should be on the 3rd folder).

Post by mondinmr on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
I have found a very interesting solution using: IoConfigTaskMap IoConfigConnectorMap IoConfigChannelMap The first is the list of IO tasks. The second is the connector for each IO module in the IOMap. The third is the individual input or output on the IOMap. One of the properties of the connector is another pointer to a connector, which corresponds with the connector of the EtherCAT slave. Through this information, it is possible to understand to which EtherCAT slave an IO connectormap corresponds. I am attaching an FB that allows for the construction of an IO map and finding the pointer to the actual IOs in the IOMap based on the bitoffset.
