II–2
During normal operation the gateway produces a
periodic (250 millisecond) “heartbeat” signal on the
network, which is used by all field devices as a part of
their network fault isolation routine. Every fourth
“heartbeat” (1 second intervals) also includes a time
and date message that is used by the field devices for
logging calibration, alarm, and other events.
The gateway has sufficient non-volatile memory to store
configuration data for all networked field devices, which
is downloaded to the gateway from the OIS.
Faceplate Description
The faceplate provides four relay LEDs and one fault
LED, a digital display, a bar graph, and a reset
pushbutton. See Figure II-1.
DIGITAL DISPLAY
The digital display is a three digit “seven segment”
display. During normal operating conditions, the
display indicates “000.” When a system event occurs
(alarm, fault or calibration) the display sequentially
shows the device address, followed by device
identification code, followed by device percent full
scale/fault code/calibrate signal.
Each indication is shown for 3/4 second, followed by a
1/4 second delay before going to the next indication.
If more than one event should occur, the entire display
(digital display and bar graph) will track the status of
each address where activity is occurring by sequencing
through each event by order of address.
DEVICE ADDRESS
All three digits are on and the decimal point for each
digit is also on. Up to 250 addresses are available
(displayed 0.0.1. to 2.5.0.).
DEVICE IDENTIFICATION CODE
See Table II-1 for device identification codes.
DEVICE PERCENT FULL SCALE/FAULT
CODE/CALIBRATE
The display follows the sensor input in percent of full
scale up to 100% full scale. A negative sign is used to
indicate a negative zero drift condition. See Table II-2
for the status codes used by the gateway display.
A fault condition is indicated as “FXX,” with F indicating
that a fault has occurred and XX identifying the type of
fault that is detected.
If a detector is being calibrated, the display will show
“CAL.”
BAR GRAPH
The 20 segment bar graph tracks the input signal from
the sensor, providing a 0 to 100% full scale reading of
sensor input.
