The solution is: If you are using an s7-1200 with firmware lower than 3.0 or an s7-1500 with firmware lower than 1.1. You need to indicate de number of bytes of the pointer like: CALL DPRD_DAT LADDR :="H1_AxisH_Status_Control[AI/AO]" RET_VAL :=#_RetVal RECORD :=P#DB10.DBX0.0 BYTE 4 With the newers versions of firmware you can copy data directelly to the structure name like: CALL DPRD_DAT LADDR :="H1_AxisH_Status_Control[AI/AO]" RET_VAL :=#_RetVal RECORD :="IO_Lenze".H1.H.In Best regards, Miguel Pinho
