Thanks Tim! This was exactly the functionality we were looking for. We are already using implicit checks to check for divide by 0 errors, we will add implicit checking for array bounds.

yes I think you need to build the kernel drivers for the CCAT driver for the backplane ETC networkcard https://github.com/Beckhoff/CCAT/

Thank you for your response. Is there documentation for the commands? I spent a lot of time trying to figure this out. I have a potato computer at home, so I'll have to test this later.

Post by riccardo on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
GoodMorning everyone. I have a system that, in case of alarm, have to block. When the operator logs in must have to acknoledge the alarm and should operate in the system freely. To perform this I detect the logged User by (VisuElems.CurrentUserGroupID <> 0) with a similar code to the the following: PROGRAM AlarmMngt VAR alarm : BOOL:= FALSE; Ack : BOOL:= TRUE; PushBottonOpening : BOOL:= FALSE; Valve : BOOL := FALSE; Flag: BOOL := FALSE; END_VAR IF alarm AND Ack AND (NOT Flag) THEN valve := FALSE; PushBottonOpening := FALSE; Ack := FALSE flag := TRUE; ELSIF (NOT alarm) AND Ack THEN flag := FALSE; END_IF (* if the system is in alarm but there is a logged operator that acknowledge the alarm the system allows the valve opening.*) IF (VisuElems.CurrentUserGroupID <> 0) AND Ack AND Alarm AND PushBottonOpening THEN Valve := TRUE; ELSIF (VisuElems.CurrentUserGroupID = 0) AND Alarm THEN valve := FALSE; END_IF The problem I have is in the last 5 lines of the code: Even if there is a logged in user, the GroupID variable is subjected to a refresh that cyclically set for an instant it to 0 and this close the valve making difficult to the user to work Now I solved it creating a time hysteresys cycle but it is not a good solution. Someone is able to explane me why the GroupID variable is sobjected to this refresh and how to stabilize to avoiding it? Thank you in advance, Riccardo

Post by suyash on Device User Logon ^{CODESYS Forge talk (Post)}
Hello. Basic Info : I am using Codesys Control For Raspberry Pi SL. Version 4.4.0.0 Engineering version : CODESYS V3.5 SP19 Patch 1 (Its a old application) I am facing a difficulty with the "Device User Logon". The window (screenshot attached) pops up during login. When i enter the credentials (which i feel are correct), the windows pops up again no matter how many times I enter. To ascertain, I tried entering the incorrect credentials during which its clearly specifying that i have entered them incorrectly (which is why I am quite certain about the credentials being correct). I even tried going into Communication Settings > Device(drop down) > Change Runtime secuirity policy . However it again asks me for credentials which keep popping up again and again. I am thinking of upgrading the runtime to the latest version of 4.20 Will it cause any issues with the paid license? Please suggest me a solution. BR, Suyash

Post by imdatatas on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, I have experienced such situations with some servo drive devices in the past. The home completion information is reported to the upper controller by the slave drive with the states of the relevant bits in the StatusWord (for example; 6041h Bit10, Bit12 in Home mode). If the states of these bits are correct in terms of number and state but the motor does not actually perform the action; You can contact the slave drive manufacturer. There may be a problem with the device firmware. Another area you can play around with is looking at the settings in the "Advanced configuration" for Softmotion axis on the page the link to below, and trying it out and using the one that works for you. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cmd_add_softmotion_cia402_axis.html A method I recommended worked for a user as in below message. https://forge.codesys.com/forge/talk/Engineering/thread/40bc82454d/ I hope your problem will be solved as soon as possible and by sharing the result here, you will help others to know and overcome it. Good luck. Best regards, Imdat

Post by struccc on Wish: CODESYSControl.cfg - again ^{CODESYS Forge talk (Post)}
Before creating this topic, I was browsing the search results for CodesysControl.cfg - many results, and I remember very well, it's a problematic issue for a long time. To summarize: there were many requests for documentation on this file - the most comprehensive reply is: https://forge.codesys.com/forge/talk/Runtime/thread/ebbf851a3d/#eb85 Hi, not really, this is covered by the manual which you get if you use a runtime toolkit which is not free of charge. Maybe we need to extract the config file part from that documentation if that is possible. BR Edwin I am not sure how much is this relevant, since we buy SL License directly from CODESYS... I think it is a reasonable demand, to get documentation on the configuration entries affecting the documented behaviour of the runtime system and it's components The actual reason I bring up this issue again can be read here: https://forge.codesys.com/forge/talk/Runtime/thread/febad3cc40/#0e12 but mostly my frustration about noticing some new, unknown and undocumented entries in my configuration file. Again. And this happens a lot recently. Just some examples: Changes with SysFile - and mandatory use of IEC path Introduction of Mandatory user management File transfer service now disabled by default SysProcess - allowed commands The above mentioned CmpApp parameters... And finally (Regaridng windows install): With the newer versions, the installation directory (together with the configuration file) tends to hide itself to some super silly location under the roaming profile data of local system account. I am not sure if this change was documented somewhere, but was a very unpleasant one. Someone could please explain the reason and the concept of the introduction of this release specific directories (I am sure, there is a good reason) - how to use them properly? - How to re-introduce user configuration (to preserve configuration data between versions)? - How to do version - to version migrations properly? - How to keep old version of runtime available and ready to start with it's original configuration and application? - ... Therefore, the lack a regularly updated description of CodesysControl .cfg , including all the configuration entries, together with their default values for different runtime versions is really a big deficiency.* This should be done for all components storing or just seeking data from this file... (Maybe there is such thing but I failed to find???) It is regularly causing trouble when introducing a new version (together with the long awaited bug fixes and enhancements), what has changed it's default behaviour for security or other practical reasons. I agree this is very important, and it is logical to change the default options: But it must be documented historically, and make it easily available, so we can prepare better for the upgrade of the runtime. Forge talk is a great source, but not very practical for this kind of documentation purposes... Thanks in advance for CODESYS staff 🙏🙏🙏 (Ps.: It would look rather silly, if some members of the user community prepares this documentation on a Forge Wiki page... Or??? Should we?)

Post by pauloricardoss on Codesys Control Raspberry PI 4.10.0 - missing 'Update Raspberry PI' option ^{CODESYS Forge talk (Post)}
I am having the same problem. 'Update Raspberry PI' disappeared from the 'Tools' menu. Using RaspberryPI 3B+, Codesys V3.5 Sp21 + RaspberryPI Package 4.16. I installed the package as Administrator, executed Codesys as Administrator I also tried to connect using the deploy (even with ssh and everything enabled on the RaspberryPi I received password denied). I used in the past the same equipment with Codesys V3.5 Sp18 and RaspberryPI Package 4.08, it was really easy. (I also did a brand new RaspbianOs installation to make sure that nothing affect the connection). Anyone, knows how to fix it? Thanks,

Post by mp9876 on Problems with simulation in Window 10 ^{CODESYS Forge talk (Post)}
Hi Automa, it seems the solution you were bringing up on 2022-04-06 could really help me as I did not remember the password I initially set. My problem though is that I am using Codesys Control Win V3.5 SP19/60 (64 bit) and I cannot locate any of the files you listed up there. I have been looking inside folder: C:\Program Files\CODESYS 3.5.19.60\CODESYS\ and they appear not to be present at all neither in the CODESYS folder or any sub-folders. Uninstalling and re-installing unfortunately does not do the trick. Any idea how I could get out of the ditch on this issue ? Anyone else maybe ? Thanks

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods) ^{CODESYS Forge talk (Post)}
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?

Post by william on Unit testing support / libraries for EcoStruxure Machine Expert (CODESYS) ^{CODESYS Forge talk (Post)}
Hi, We are investigating available libraries and frameworks for automated PLC unit testing in Schneider EcoStruxure Machine Expert. Specifically, we are looking for: Assertion libraries or test frameworks compatible with Machine Expert CODESYS‑based solutions that are not TwinCAT‑specific Any official or community‑recommended approach for unit testing FB/FC logic offline We have found several open‑source examples, but many appear to be TwinCAT‑dependent and therefore not compatible. Are there any known libraries, best practices, or recommended approaches for implementing unit tests in Machine Expert? Thanks in advance.
