Post by tvm on VisuFbFrameBase.SetInputPositionData: The element id for the input position cannot be determined ^{CODESYS Forge talk (Post)}
This came up again today, so I'll post the fix for future reference. Happens with Schneider Machine Expert 2.2 and M262 controllers. Add this bit of code to a program called from the visu task //disable "VisuFbFrameBase.SetInputPositionData" log messages, which fill up the logs IF VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.GetListenerCount() > 0 THEN VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.RemoveValueChangedListener(VisuElems.Private_Visu_Globals.g_ValueChangedListenerManager.listenerForOnValueChanged); END_IF

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Hi Everyone, For a fast monitoring system I am using Ethercat oversampling and timestamping inputs. As the customers has a lot of different configurations out in the field, we went for a dynamic Ethercat configuration. Already got the whole detection chain working but now I am stuck since two days in debugging the configuration. Here are my quesitons: I extended the dynamic config example for the EL3632 16#0E303052: //EL3632 pSlave^.SetDCSettings(TRUE,TRUE,80,80,TRUE,4000,0,0); pSlave^.AddSyncManager(16#1000,128,16#26,TRUE,3); pSlave^.AddSyncManager(16#1080,128,16#22,TRUE,2); pSlave^.AddSyncManager(16#1100,0,16#4,TRUE,1); pSlave^.AddSyncManager(16#1110,214,16#20,TRUE,0); pSlave^.AddFMMU(0,214,0,7,16#1110,0,1,1); pSlave^.AddFMMU(0,1,0,0,16#80D,0,1,1); xKnown := TRUE; This leads to a PLL Error for these devices. I double and triple checked the configuraton, but cannot find the issue. There seems to be one difference: the config dialog creates a startup parameter: 16#10F3:16#05, Name: Command_0, Value:0. Bitlen: 16, Stop on fault: false, jumpt at fault: false: next line: 0 a) I do not find information on how to set this in my code. Can you help me there? b) Without trying to set the value, I get a PLL error for these devices in the master log. Is the config wrong? c) Do I need to set the Master to Autoconfigure or Manual? I used autoconfigure for my tests. The stack creates input data addresses for the slaves input data range (pSlaves[i].InputData) which are different from those created when I use the Engineering tools dialogs to configure Ethercat. Specifically, the addresses seem to be aligned at 16 byte boundaries when they are created using the engineering tool, but may appear at uneven addresses when I use the script in dynamic config. I did not try to access ULINT at uneven addresses yet, but I am suspecting this may be a problem. Do I need to manually align the addresses ? Any help is appreciated...

Post by ophelia on Phantom Test Slot Preventing Suite Completion ^{CODESYS Forge talk (Post)}
Hi all, I'm working with a CODESYS 3.5 unit test framework on an embedded Linux PLC and running into an issue where a phantom test slot appears in the results that never completes, preventing the full test suite from ever finishing. The symptom: A blank-named test entry appears in the results table with an ever-increasing action count. It stays as "Testing" or "Failing" indefinitely. Because it never closes, bAllFinished never goes TRUE and the final report is never generated. Question: Has anyone seen this kind of phantom slot issue in a CODESYS unit testing setup? Thanks

Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

Post by caprez95 on Deleting the trend recording history ^{CODESYS Forge talk (Post)}
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by gunstr on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
Thank you very much for the quick answer! The RPi hw were delivered last week so it's probably a resent version. I found an old scrapped board (2 years or so) with a broken GPIO that I tested with the same SD card image and with that board Codeys can run for the full 2h demo period without issues. Then I went back the the new board to test the 4.17.0.0 release but the installation fails... [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesyscontrol started [WARNING] Unable to detect Raspberry Pi Architecture. Setting armv6l as default, you can change this through the settings panel. [INFORMATION] Standard output: codesyscontrol stopped [ERROR] Expected exit value of command failed: expected 0, received 1 [WARNING] Error setting the Raspberry Pi Architecture [ERROR] Error installing codesyscontrol Do you have any idea what could be the reason? I'm using an OS image including Python drivers for LCD and some I/O:s from last year to keep things stable, but also after upgrading with sudo apt update && sudo apt upgrade I still get the same error Reverting back to 4.15.00 works fine: [INFORMATION] Standard output: create and install daemon [INFORMATION] Standard output: codesysedge started [INFORMATION] Successfully installed codesyscontrol [INFORMATION] Successfully started CODESYS Edge Gateway for Linux [INFORMATION] Successfully started CODESYS Control for Raspberry Pi SL but as before the Codesys services stops after 30 seconds. And I noticed that the Codesys control stops and is not reachable also if I have no application loaded.
