Archiving Retrieving Issue

Hello YA;

Look in the Blocks folder of your Step 7 program, look at the details for your FC105 and FC 106.

If you see FC105 "Scale" and FC106 "Unscale", both authored by "Siemens", then these are standard blocks (from the TI-S7 converting library) that are used to standardize analog inputs and outputs.

Like all blocks developed by Siemens for Step 7, you can use the functions but you cannot open them; this ensures that the blocks remain unmodified and work the same for everyone. They are protected by a mechanism called "Know-How Protect".

You can find instructions on how to use these functions with the online help of Step 7, or in such entries in Product Support:

- What should you watch out for when converting from TI programs to S7 programs?

- How and for which analog measurements can you use the function FC105 "SCALE" to convert the integer values (INT) into real number values?
