Im using Codesys V2.3.9.35 in Windows XP.
I Have Turck Bl20-PG-EN-IP PLC.

I can login to the PLC with out problem and i can also Rebuilld all without error message. But when i download my program to the PLC i get:
Unresolved external pou:s

I have the Librarys in Codesys. I have no clue what it can be.

By the way i´m a student and a beginer in this.

Thanks in advance!!

check the library tab, when the lib is red, codesys can not find the path or the lib.
add the library and delete the rd one.
