BINARY GLOBAL SCREEN
CLOCK MODE
Binary Global Screen’s WCC III Logical Address is GBXXX, where GB = Global Binary and XXX = Global Binary Address
Mode: 7 Clock
Specifi es the mode used to generate the ON or OFF value of the
binary global. Because this is a choice fi eld, the following list of
available choices will be displayed at the bottom of the screen:
<Combinatorial, Compare, External, Alarm,
Alarm-by-Class, One Shot, Clock, Delay, PWM,
Lead-Lag>
Make your selection by pressing the <space bar> once for each
choice until the desired mode has been selected, and then press
<Enter> . Whenever you change modes, you must fi rst clear the
existing screen by using the <Ctrl> <Home> feature.
The Clock mode causes the binary global to generate an ON value
for a programmable amount of time and then an OFF value for a
programmable amount of time based on a binary input value being
either “Off” or “On”. This global will constantly cycle off and on
for the programmed amounts of time as long as the binary input is
in the desired “On” or “Off” state.
NOTE: Since this global is based on time (i.e. clock mode),
if the binary input changes state during the “On” time or the
“Off” time, then this binary global will change to the OFF
value. If the binary input changes state again it will turn ON or
OFF depending on what state this global should be in based on
time.
Example: Value is ON for 120 seconds and OFF for 120 seconds
when 5L3 in ON.
When 5L3 is initially turned ON, this binary global will turn on.
After 20 seconds, 5L3 is turned OFF, so this binary global will turn
off. After another 30 seconds, 5L3 is turned back ON; now this
binary global will turn back on for the remaining 70 seconds and
then go to the off mode for 120 seconds.
