Data Record Format - Sensor Electronics SEC Millenium Series Instruction And Operation Manual

Data Record Format

Data is output to the RS232 port in formatted text, in a record format. There is one
record per status item. A status item may be;
(1) Global Status- i.e. status of highest alarm/fault level of all zones, including a
tally of all devices configured on the bus, a tally of all devices on line, and a tally
of all the devices that are off-line.
(2) Zone Status- i.e. status of highest alarm/fault level of all devices within the given
zone, including a tally of all devices configured in the given zone, a tally of all
zone devices on line, and a tally of all zone devices that are off-line.
(3) Device Status- i.e. Current gas level and alarm status of the current device.
There is one record for each status item; hence there will be one record for global
status, and sixteen (16) records for each of the sixteen zones. There is also one record for
each device, therefore up to 254 records for 254 configured devices (actual number will
depend on the number of actual configured devices for the bus). This gives a possibility
of up to 1 Global + 16 Zones + 254 Device records = 271 total possible records (if all
three categories are selected for output). There is also one (not counted) Top of Loop
indicator record to indicate the beginning of a new scan.
All records are delimited by angle brackets < >, and terminated with carriage
return/line feed characters, so that one record appears per line on a standard RS232
terminal or applications such as Windows HyperTerminal. There are six (device) or
seven (global or zone) fields within a record, each separated by a pipe character (vertical
bar) |:
<A|B|C|D|E|F|G>
A = ID: Is either "ALL" for global status, 1-16 for zone status, or 1-254 for Device
ID.
B = NAME: "GLOBAL" for global status, "ZONE" for zone status, "RELAY8" for
an 8 coil relay module, "RELAY16" for a 16 coil relay module, "AIM" for
analog interface module, or a gas name abbreviation for gas sensor (such as
"Chlorine" or "Methane"
C = VALUE: For global or zone status, this will be the number of devices
configured for the entire bus (global) or zone (format: "CF 000"), for Relay
modules this will be empty ||, for AIM and gas detectors this will contain the
value (gas detectors, this will be the formatted gas level, precision set to scale of
sensor range; AIM this will be the analog voltage level).
D = UNITS: For global or zone status, this will be the number of devices online
either for the entire bus (global) or the zone (format "ON 000"), for Relay
4
Note: during sensor power-up, it may be empty, appearing as two || symbols with no space.
