NOTE: Modbus refers to the hexadecimal address location. These parameters are formatted as unsigned 16
bit integers. Any real number such as temperature can be evaluated as a signed number, other parameters
are bit mapped words that must be evaluated as single bits are bit groups.

IDLE
Idle processor count. This number should never
be 0.

RSETPT
Remote setpoint sent to the instrument from the
Host port. This number has to be scaled to the
range of the displayed process value based on the
decimal point and exponent settings of the
instrument.
Range = -999 to 9999
Default = 0.000
For example: If the process = oxygen, display
decimal point = 2, and exponent = 6, as remote
setpoint of 1234 would be interpreted and
displayed as 12.34 ppm.

LSETPT
Process setpoint set by the operator through the
Setpoint menu. This number is scaled to the range
of the displayed process value based on the
decimal point and exponent settings of the
instrument.
Range = -999 to 9999
Default = 0.000

TSETPT
Timer setpoint set via the Host port or locally.
Range = 0 to 999 minutes
Default = 0
READ/WRITE
04 4
PROC
This value is the calculated process value shown
as an integer. The decimal point and exponent
values are required to determine the actual scaled
value.
Range = -999 to 9999.
For example: If the process = oxygen, display
decimal point = 2, and exponent = 6, and PROC =
1234, then the actual value and displayed as 12.34
ppm.

TIME
This is the remaining time on the timer as it counts
down from Time Setpoint. Zero indicates timer has
stopped.
Range = 0 to 999 minutes
Default = 0

ALARM1
Alarm value is based on process value display
decimal point and exponent. Both are required to
determine the real alarm value.
Range = -999 to 9999.
Default = 0000
