Tielenaar Posts: 5 Rating: (3)	Hi, Check your "standard library, system function blocks" after you opened an FC then in STL: CALL SFC20 SRCBLK := P#DBxx.DBXy.z BYTE 20 RET_VAL := MWzz DSTBLK := P#DBoo.DBXp.m BYTE 20 After calling SFC20, the 3 parameters appear automaticly. P# states an any-pointer DBxx.DBXy.z = the start adres of your souce block, BYTE 20 states the length in bytes MWzz = a free MW for diagnostic DBoo.DBXp.m = the start adres of your destination block, BYTE 20 states the length in bytes SFC20 = the standard blockmove instruction which is included in the standard library. Good luck, Tielenaar

Good luck, Tielenaar That is great for S7-300+, but there is no standard library nor STL for S7-1200 TIA Portal V10.5 Basic SP2.
