Attached is a Step 7 project that has been run using PLCSIM. Currently the project flashes Q0.0
One line in one of the blocks would need to be modified to flash Q0.1 instead - which line in which block ?

Please send answers by PM

Those that don't have Step7 at home can't play.

Hey everyone,
Anyone that wants to play can download a demo copy of WinPLC7 and import the project. Here is a link ftp://www.mcaps-inc.com/1VIPA%20Manuals/software/WinPLC%207/

If it allows one to play by just looking it would be a bonus.

Yes, you can look but you can't execute the program.

Don't be mad if maybe i give a part of the sollution
in your code after you strip the TOD you do this
= [AR1,P#8.0]
Can i assume that this is the value that you take to FC5.
And is it correct to assume that it is the value out of byte 6 (see attachment)


I can make the Q1 flash but probably not in the correct way hehe

Got Struck up in the first step itself.
My PLCSIM does not shows Q0.0 blinking, PLC is permanently in STARTUP mode.On doing the Cold Restart PLC comes in RUN mode but again without Q0.0 blinking !!
Is it a part of the puzzle or what? I do not see others complaining of this !

This program stays in startup mode and never goes into run. Where are you monitoring Q0.0 ?
