Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
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.

Post by nz-dave on Bool turning on in case stament in wrong state? ^{CODESYS Forge talk (Post)}
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 also thought that if I had logic writing a value to this variable, then it would override the force anyway, since I thought that the force request was only applied at the beginning and end of the PLC scan. But this doesn't seem to be the case, the force persists throughout the logic regardless of what I write to the variable with logic

Post by jmfernandes on OpenDir always in error ^{CODESYS Forge talk (Post)}
Hello just to give more feedback the error I get is "ERROR_UNKNOWN :represents raw value of 5110" in File.DirOpen. The xDone never gets true, and I never get the listing of files (csv files in this case). In the hDir i get the value of 0 for a DWord!?

Post by jari-koivuluoma on Problem trying Net Base Services 3.5.15.0 TCP connection ^{CODESYS Forge talk (Post)}
Solved. Just in case that someone else is now to this also. It seems that the xDone of the TCP_Connection FB goes true once client disconnects and then you need to reset the FB by setting the xEnable to false.
