Hello Igor; There are 3 parameters for SFC20 "BLKMOV". The first is SRCBLK (source block), and it must be formatted as an ANY pointer. In your particulkar case, it would look like P#M100.0 Byte 16. The second is RET_VAL, of INT type; this is an address you reserve for your status/error code once the SFC 20 is finished executing. So it could be MW20, for example. The last is DSTBLK (Destination Block), also of type ANY pointer; in your case, it would be P#M200.0 byte 16. If you have trouble understanding the structure of an ANY pointer (it points to the LSBit of the first byte of the pointer zone and a length in bytes, words,... open the online help of Step 7 and search for ANY pointer. The explanation should be quite clear.
