HOW TO MOVE SET OF CONTINUOS N ELEMENTS OF NON-ARRAY DB TO PLC TAGS(LIKE M0)

FOR EXAMPLE TO MOVE 

IN A SINGLE INSTRUCTION DB10.B0 TO DB10.B20(ALL ARE BOOLEN TYPES) TO INTERNAL PLC TAGS LIKE M0 TO M20.

KINLDY HELP ME IN THIS PROGRAMMING.

I CANT WRITE MOVE COMMAND FOR EACH BLOCK AS I HAVE SOMETIMES HAV TO MOVE CONTINUOS 100 ELEMENTS.

REGARDS,

DEVA

When using the S7-1200, the SCL command POKE_BLK:

Do know that the DB you use as source should NOT be optimized.
(Right click & Properties of the FB .. picture show as activated.. should be deactivated)

Please tell me.. why do you want to do this task?
M-bits are less efficient than the memory from DBs.

kindly explain it so it ll b helpful or send me exampl program in ladder logic..

(smile) I'll tell you what....    you explain what the code is about that you posted at the start of the thread and then I will happily explain what I have put down.

Just to try and get common ground.... do you know programming languages such as C++?

... if you second question is your actual goal, please let me know that too so we do not spend more time on the original question. (thanks)

Regards.
