Post by anderson on function block output ^{CODESYS Forge talk (Post)}
so it is not possible for me to use the function blocks and through them I can select the digital outputs of the PLC so that pulses and direction are output, or some function block that does this reading and in it I can program the pulse and direction outputs for the drive?

Post by scarter on Import/Export PLCOpen xml Task Configuration ^{CODESYS Forge talk (Post)}
I'm Having the same issue. If I highlight PLC Logic and import it erases everything else and replaces the Task config. If I highlight the Application I get the same result. Simple manual fix is click and drag the task config onto the origional Application, and delete the second one. Easy fix but not the expected result of importing task config.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger yes I have been using xDoubleStorage It happened again and I checked and the files were still there with there contents, restarting codesys or rebooting would not even reload them. Doing a download and then starting the PLC loaded them and began working again. Some sort of mismatch error or something?

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

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 srouse on PFC200BUS not running ^{CODESYS Forge talk (Post)}
I started a project in codesys for a WAGO 750-8212 PLC and I am working on getting online with the controller. I can log in to the controller and I can see and control all of the fieldbus couplers that I have. I am unable to get the internal bus working. It just says that the bus is not running and when I scan or devices nothing shows up. Am I missing something important in my device tree?

Post by athuum on Error 'Library not found' and 'Unkown type' ^{CODESYS Forge talk (Post)}
Hello, I am getting the following error and warning when trying to download a project into a PLC: - Library CmpTargetVisu has not been added to the Library manager, or no valid license could be found - Unkown type: 'CmpEventMgr.EventParam' As far as I can see, both are included, and licensed, in the library manager (see image). What could the problem be, and how would I resolve this?
