Step 7 March 09 Puzzle

L D[AR2P#0.0] · Feb 28, 2009

The attached project has been run in PLCSIM and flashes Q0.0
The flashing is achieved by OB35 which has been configured to run every 500ms, and the code in OB35 is as follows:

Code:

AN Q0.0
= Q0.0

The task is to modify the supplied OB35 so that it will flash Q0.1 instead. The restriction is that you must not use the S7 block editor to modify OB35, nor replace OB35 with one from another project.

Sorry man, what do you mean with "restriction is that you must not use the S7 block editor"?

Here's a picture of the editor in use. This is what you cannot use. (because, lets face it, if you could, the puzzle as proposed wouldn't be a puzzle

Can i ask why the Re-wire function doesn't work for me? it allways gives me following message

Address list:
Old address: New address:
Q0.0 Q0.1
Block list:
OB35: Block with this language ID cannot be rewired.
