Copy DB siemens

Hello first time in this forum!
I have a problem not beacause im from Sweden
I would like to copy a whole db in a siemens PLC s7 300 to another db. Ex db 1 dbw1-dbw60 to db2 dbw1-dbw60. Ofocourse I can use the ordinary L db1.dbw10
t db1.dbw10, but someone must know an easier whay to do this.
With Best regards Mikael Viking Augustsson

SFC20 Blockmove is needede for such operations

OK found that block. But if you have a alot of varible, dbw in the block for example dbx0.0-dbx0.7 dbb1 dbw2 dbw3 and dbd 4 is this still working? And I don´t understand how this sfc 20 should be filled in ? Maybe im stupid but I still can´t understand it
CALL "Copy Data Block 1"
QTYP:=MW10
QANF:=1
LAEN:=60
ZTYP:=MW20
ZANF:=1
FEHL:=MB20
NOP 0
For example in mw 10 (QTYPE) I tried to fill in... Define the source block in my application db 10. What should stand in mw10 ? 1 for db ?
ZTYP the block should be copied to db 20. WHat will I write in ZTYPE
ZANF The copy should start on dbw0 the same as the original block.

Qanf source start. DBW 0 in my case should it be a zero there.
Laen. 60 words should be transfered
I hope you understand my poor english
I hope someone could answer me.

Blocks must be same size. EG copy db1 100 bytes to db2
SFC20 input SRCBLK: P#DB1.DBX0.0 BYTE100

SFC20 output DSTBLK: P#DB2.DBX0.0 BYTE100
SFC20 output RETVAL: State variable

Thanks s7xp.com

Hello fagerstaPLC;

Very strange, the CALL "Copy Data Block 1" you show has nothing to do with Step 7 SFC block SFC20 that s7xp.com is talking about. What library did you find that block in?

This is what a call for SFC20 "BLKMOV" ( from the "Standard Function Blocks" library) should look like:



The Source (SRCBLK) and Destination (DSTBLK) parameters use an "ANY pointer" format; this allows you to indicate in a single format the type of data, the start address and the length. Check the online help for ANY pointers for more details.

Hope this helps,
Daniel Chartier

It must be FC94 "Copy Data Block 1" from the S5-S7 conversion library that fagersta has found in stead of SFC20 "BLKMOV".

Propably he need the SFC20 instead of the other one.
