Introduction.

Workshop PG5 Exercise Chapter 4
In the Family “Time related” you will find a Fbox called “TIME” this Fbox reads the
time from the PCD. The output shows the time as an integer value off six digits.
HHMMSS. The color off the output is different to the color off the lines we had in
our first example. That is because each and every type has its own color like:
• RED lines are binary value
• GREEN lines are integer and so on.
You can’t connect two lines that have different types and you can’t connect two
outputs either.
Goal:
You learn the difference between different types ( binary, integer,…. )
You learn how to read the time from the internal clock
You learn to how to compare values.
You learn to work with symbols rather then with fix addresses.
You learn how to document your program.
You learn to set the internal clock.
Quite a lot for one example I know.
