use a realtime capable target, not Control Win. Either a realtime patched Linux or Control RTE on Windows.

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.

Post by schnepper on Error building Extension SDK Linux code ^{CODESYS Forge talk (Post)}
Solved: I started from a fresh project and everything worked. I had a Function Block in the project at one point and deleted it. I think Codesys doesn't fully clean up on deletes.

please delete the contents of the following directory - /var/opt/codesys/.cmact_license/ then start a new SPS and then the activation should work (then you have a new empty UFC SoftContainer)

I am curious if there is a function block or function that will allow me to monitor the J1939 CANBus and pull out all of the SAs that are on a particular bus, without having to have them loaded in the J1939 manager?

Post by tvm on Timer On Vijeo ^{CODESYS Forge talk (Post)}
Vijeo doesn't support TIME variables, so the easiest thing to do is convert to a STRING in your program, and use that variable. You could use TimeAsString:= TIME_TO_STRING(TimeVar) to get a string that looks like this: T#5h10m45s200ms

Is there perhaps a place where I can see examples of programming with different instructions? This would be a great help. Maybe there are some places where ready-made programs are posted that can be downloaded and tested? /Klaus

I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?
