MOVE_BLK in s7-300/400

Good day!

May be it exists an equivalent of block "MOVE_BLK" of s7-1200/1500 for s7-300/400?

Requirements are:

-indirect addressing of source and destination area,

-floating quantity of movement bytes,

-working with arrays of data

I tried to make it use standard block MOVE with FOR loop in SCL but it consumes a lot of plc resources in s7-315-2DP:

Thanks.

Hello,

Perhaps you can use SFC20

Here are some links:

saving process data in the main memory, copying data blocks with "BLKMOV" (SFC 20)

Parameterizing the SFC 20 (BLKMOV) with ANY Pointer

Best regards,

 Dear Wizard, thanks for your answer, may be you have an example from second link "2_progs_blkmov.exe", because it can't be downloaded now?

 Dear Qwazee, thanks for answer, may be it was some problems with internet connection. Now it is ok.
