75 °
50 °
On Off
1. The first Data Limit
process detects when
the physical specimen’s
temperature reaches
75
° C.
The Group process holds the
individual processes used to control
the cooling fan.
2. The first Digital Output
process sends out a
pulse that turns the fan
on when the physical
specimen’s temperature
reaches 75
° C.
3. The second Data
Limit process
detects when the
physical specimen’s
temperature drops
to 50
° C.
