I can also add the kernel log messages from the same time. Seems like some kind of packet storm to the PLC?

One i wrote this to measure elepse time When xMeasure is true is starts en when false it stops and time is messured. FUNCTION_BLOCK FB_ElapseTime VAR_INPUT xMeasure: BOOL; END_VAR VAR_OUTPUT xRisingEdge: BOOL; xFallingEdge: BOOL; tElapsed: TIME; ltElapsed: LTIME; ltPrev_Elapsed: LTIME; ltElapsedMax: LTIME; END_VAR VAR xLastValue: BOOL; LTIMEStart: LTIME; LTIMEEnd: LTIME; tonReset: TON:= (IN:= TRUE, PT:= TIME#30S0MS); END_VAR ------------------------------------------- xRisingEdge:= (xLastValue XOR xMeasure) AND xMeasure; xFallingEdge:= (xLastValue XOR xMeasure) AND NOT xMeasure; IF xRisingEdge THEN ltPrev_Elapsed:= ltElapsed; LTIMEStart:= LTIME(); END_IF IF xMeasure OR xFallingEdge THEN LTIMEEnd:= LTIME(); END_IF ltElapsed:= LTIMEEnd - LTIMEStart; ltElapsedMax:= MAX(ltElapsedMax, ltElapsed); tElapsed:= LTIME_TO_TIME(ltElapsed); xLastValue:= xMeasure; tonReset(); IF tonReset.Q THEN tonReset.IN:= FALSE; ltElapsedMax:= LTIME#0NS; END_IF Meaby this will help.

If you use LTIME() you will be very accurate and be able to have a normal task cycle time.

Post by timvh on EXCEPTION [watchdog] how to find position cause ^{CODESYS Forge talk (Post)}
Monitor what your current cycle time is (in the Task Configuration when you are online). If this is sometimes close to 200ms, then change your code (e.g. limit the loops, or prevent copying a lot of data between objects). Or just set the Watchdog time (or sensitivity) higher if you don't care that it sometimes takes longer than 200ms. If you want to find out which objects in your application consume the most time, then buy a PDE (Professional Developer Edition) license. With this you get a license for the Profiler. This can help you a lot to find the root cause, because it will create a nice overview of all objects, their calls and the time (percentage) it takes to execute it.

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.

Post by mwandy on Codesys Project Protection ^{CODESYS Forge talk (Post)}
I'm having trouble finding clear answers on this. I'm looking for a way to make a Codesys project password protected so that if the project is distributed it can be used to log into a controller to view and debug logic. At this same time I want to prevent the project from being saved as well as edits being downloaded to the controller. Basically I want to make a whole project view-only. What is the beat way to achieve this? I have had minor success with access rights, which solves the problem with trying to login if the project doesn't match what is in the controller. However with this solution, edits can still be made and saved, possibly corrupting the core project, preventing future logins. Any suggestions?

Post by danwoodlock on Rpi zero w lost license after 4.11 update ^{CODESYS Forge talk (Post)}
Hello all, Encountered an issue with my zero which seems to have happened after the 4.11 update. It now runs in demo mode (2hr) and I am trying to see what the appropriate steps are prior to contacting codesys directly. Background: I recently did a fresh install of w11 on my pc, so it seems "c:\ProgramData\CODESYS\Licenses\" only has information related to my pi5, which I licensed just this past Friday. I have all my license documentation about my rpi zero as far as the emails received, but when I try to claim using the ticket number it says its already been used, or something to that effect, which it was. Currently trying to perform device license reader, which is taking some time.
