Hello friends of Step7, I'm using a CPU 416-5H together with Step7 (V5.5). When configuring HW-config, I get the dialog to configure the Report System Error (CPU messages) also (see https://support.industry.siemens.com/cs/ww/en/view/5416665) I'm using OB81, 82, 83, 85. When compiling the entire program, I get the warning "Block OB81 contains a recursive call". Same with OB82, 83, 85. Inside this blocks it's just written: "CALL "SFM_FB" , "SFM_DB"". Nothing more. So where is the recursive call? Thanks! Christian |
