TYPICAL USER PROGRAMS
Network No. I
l
Simple Set
Point Control
Network #l compares the value from an
analog input with a preset value in register
4009. If the input value is greater than or
equal to the preset value, coil 0001 is ON.
Conversely, if the input is less than or
equal to the preset value, coil 0002 is ON.
This comparison is performed on every
Micro-84 scan.
Network No. 2
.
Sat Point
Control
Network #2 performs a similar set point
function as Network #l, but both coils do
not go ON when the input value is equal to
the preset value in register 4009. Coil 0002
is ON only when the input is less than the
preset value. Greater than or equal input
values turns on coil 0001. Alternately, a nor-
mally closed 0002 contact positioned prior
to coil 0001 (while receiving contact 0001)
will prevent equal values from turning ON
coi I 0001.
Network #3 will turn ON coil 0001 when the
analog-input value is less than or equal to
the preset in register 4009. Coil 0002 is ON
when the input value is greater than or
equal to the preset value in register 4011.
The preset value in register 4011 is greater
than the preset value in register 4009.
Values between these will turn both coils
OFF.
Network No. 4
- “Pass Bmnd”
Set Point Control
Network #4 performs the inverse of Net-
work #3. Coil 0001 is ON only when the
analog input is between or equal to preset
values in registers 4009 and 4011. The
preset value in register 4011 is greater than
the preset value in register 4009.
