Chapter 4: Parameter passing 65
Example2:
When AT01=-100.0, AT01’s inner value -1000 is passed to other function block as preset
value. Passing to B002(T01 time base is 0.01s) as preset value. -1000 is less than lower limit of
T01 0, so automatically as 00.00;
Passing to B003(C01) as preset value. -1000 is less than lower limit of C01, so C01 preset
value automatically as 0;
Passing to B004(AR01) as preset value. -1000 is not out of data range of AR01 -10000, so
automatically as -1000;
