With regards Johannes Hello Johannes4u, There are some possibilities, please read more in section "16.2 calling function blocks " in the following manual: Structured Control Language (SCL V4, V5.0) for S7-300/S7-400 Programming You can try again by defining the FB prior to OB1 and then call the FB in OB1 with one instance DB like: [code]FB1.DB1(E1:=I0.0,E2:=I0.1);[/code] In this case , you are defining the inputs or inputs/outputs.To access the outputs, you can try the following syntax: [code]Q0.0:=DB1.A1; [/code] All needed information will be available in chapter 16 of mentioned manual.Also check the following clustered threads: HD_SCL Starting Point I hope this helps, Hamid Hosseini

The variable "set" from the VAR-section (static-data) is an internal member of FB1, which cannot be set in the call-interface the call of your FB1 should look like this: [code]FB1.DB1 (mytime:=T1, result:=variable);[/code] And please note, that the comments "Temporary Variables" and "Static Varaibles" do not match with the VAR-sections. Hope this helps! Best regards, yy1
