Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Post by westcountryewe on Persistence Variables missing and DO NOT retain from Persistence Channel when using Boot Application ^{CODESYS Forge talk (Post)}
We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise the Boot Application method because of logistical restrictions of being able to get out to every site, so at the moment it's a bit restriction.

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

The "remove unused" parameters have been added to 1.0 version as well as the "manual" removal of pins... also allowed "empty" inputs for blocks is in and the compile error described there should no longer occurs. Drag drop of variables is not yet implemented and I don't think the double-click feature yet either.

Hi, I am looking for a way to define a local variable that will be multi user independent. This is so several user can connect at the same time select frames independent of each other.

I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.

Do you still have this image, or can you tell me where I need to click to enable persistant variables? I'm getting the same error:C0244: No VARPERSISTENT

Hey mate, did you get to the bottom of this? If not, have you double checked the buttons are linked to the correct variables and/or performing the correct action? Have you tried always enabling the block to confirm false is moved to the variable if so?
