You have to write this MAIN_SHIFT: Shift_register; Registras AT %MW100 : WORD; Registras0 AT %MX100:0 : BOOL; Registras1 AT %MX100:1 : BOOL; Registras2 AT %MX100:2 : BOOL; Registras3 AT %MX100: : BOOL; Registras4 AT %MX100:4 : BOOL; Registras5 AT %MX100:5 : BOOL; Registras6 AT %MX100:6 : BOOL; Registras7 AT %MX100:7 : BOOL; -
