How to implement this application:

1. The source files (hhu2_Fc68, hhu2_Db68, hhu2_Fc119, hhu2_Fc124) are to be transferred into your S7-project
2. Make your machine specific settings in the source file hhu2_Db68
3. In the S7-symbolik list you have to assign DB68 to the symbol “_db68”
4. Translate the source files (starting with hhu2_Db68)
5. Parameterise FB1 in OB1 accordingly (example: hhu2_Ob100)
6. FC68 and FC119/Fc124 have to be called in the right order within OB1 (example: hhu2_Ob1)
