Pointer in TIA

 Hi ..

I also have same problem ..

in step7-300 , i can access input parameter "B1" of type byte using pointer

 L     P##B1

LAR2

But in S7-1500 ,

It turns to red and highlight me that

Tag P##B1 not found or not addressable via operator P# .

How can i overcome this problem .. is there any way to load address of input Parameter B1 .

-----------------------------------------------------------------------

But i have another alternative approach ?

Create temp variable TempB1 of type byte .

// Move input value to local temp variable first 

L  B1

T TempB1

// Reference local temp variable and get address of it 

L P##L0.0

LAR2 

------------------------------------------------------------------------------------

Want to know is there direct access to input parameter using pointer . ????

Regards ..,

Tun

..@William B - I don't agree with you here, as far as i see it, that's the only way to get the actual screen number out of the machine - otherwise you need to do something like "set bit" or "write value" when you load a screen - that's a lousy solution i think....

Yes you are right...
Have you used the start-up wizard in WinCC (for basic panels) before?
Have a look on how the page heading is implimented
- note also the "page opening" events.
[wink]

By the way - we use a mouse click and key recording application for repeated tasks. That significantly reduces those (previously) lousy solutions.

..it however does not matter - you are the designer of your project. [smile]

Good luck.
