I have a case statement running a process. during one of the steps it has started calling a bool var that is 2 steps further on in the case? i have even tried //commenting it out but it still turns on at the same point in the case. i have also run a trace but cant see anything that would trigger it. Any Ideas? Cheers

i would be looking at what the case variable is doing then.. sounds like there might be a logic race going on

I guess you could archive the project, open the archive and go online. Is that suffiecient for your use case?

Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

pretty sure its not. ive done a cross reference and only have one write that sets it to true. Only way i can stop it is to remove the function block call from the main pou that is running said case. its got me stumped:/

I had this problem when running the application as a Simulation. When I wrote it to the Pi all worked as expected. If this isn't the case for you, we've seen some issues with sqlite on the Pi's - so reset Origin and re-download may help in that case. Good luck, Mark

The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Okay, the solution was so simple... In my case, you first have to add the EL1918 and then the EL2904... then the connection is made automatically. I probably had something else before and then added the EL1918... then it doesn't catch the connection :/

One option could be to use a trigger variable to execute your trace and then toggle that variable from a step within a test case.

are you sure it is not used anywhere else.? does it have an address that could be duplicated perhaps? nothing external writing to it?

I had the same error. It took me a LONG way to figure it out, but in my case the problem was that I used LDATE_AND_TIME. It seems to be not supported, at least not in the Codesys version I used (3.5.16)

Have you found the way how to call any function in case the visu is opened? Like on event when the screen is opened to initialize some variables etc.? I can´t... :/

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 TimH Thanks for the information, I thought that was the case so have stepped through the code and found an error that wasn't closing the port, therefore hCom was increasing. Thanks

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
