Post by davidbo on Is it possible in the log to see previous shutdown ^{CODESYS Forge talk (Post)}
If my application does some kind of violation which makes it cast an exception it will trigger my real watchdog which results in a reboot. Unfortunately the log it seems only shows the boot sequence. Is it possible to see what happen before reboot?

Post by aconley on Static Code Analysis ^{CODESYS Forge talk (Post)}
I'm using CODESYS 3.5 SP16 Patch 6. I would like to incorporate static code analysis as part of our CI/CD pipeline. 1. Is there a way to execute the static code check from the command line or python script? 2. If you can't do it from the command line, is there a way to export the results from the application?

Hello, Has anyone tried running CODESYS Linux on Ubuntu Core? I'm having problems installing the runtime. The connection to UC cannot be established. I used the instruction: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_linux_public_key_authentification.html I can connect to UC using SSH (putty, shell). Codesys can't. Do any of you have an idea?

Post by evanclegg on Digital Clock ^{CODESYS Forge talk (Post)}
To display the current time, you’ll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Here’s an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format “HH:MM:SSuno online".

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
I have discovered a rounding error, either in Codesys or in my understanding of numbers. The attached ladder shows that when the up button is pressed the number increases by 0.1, when the down button is pressed number decreases by 0.1, after several button presses the number isn't equally divisible by 0.1. Have I discovered a bug or am I doing something wrong?

Hello, I use Codesys RTE 3.5.16.5. If I connect to the PLC I often get the following message: (see printscreen) 1. Channel timeout CMpChannelMgr. 2. Closing connection CmpChannelMgr. Can you tell me, what the meaning of this is? What does the number 1250030,1220020 resp. c400:0a0a:015a:0301 refer to? I could find any information in the online help. Thanks a lot.

A bit of work but maybe possible to make your own driver using "CODESYS Control SL Extension Package". Look at the "ExternalIoDrv" example. It is installed in "C:\Program Files\CODESYS 3.5.20.0\CODESYS\CODESYS Control SL Extension Package" when you install the "CODESYS Control for Linux SL".

Post by timvh on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
Probably best to call the FB continuously. So something like this could solve it: IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog := FALSE; fbOpenLatchSettingsDialog.xExecute := TRUE; END_IF IF fbOpenLatchSettingsDialog.xDone OR fbOpenLatchSettingsDialog.xError THEN fbOpenLatchSettingsDialog.xExecute := FALSE; END_IF TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog( itfClientFilter:= VU.Globals.OnlyTargetVisu, sDialogName:= 'visu_AlarmLatchSettings', xModal:= TRUE, pTopLeftPosition:= ADR(TopLeftDialog) );

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved
