Glossary
Adv Hi Level
Advisory High Level alarm set point. When the product level exceeds this point an
advisory alarm will be generated.
Adv Hi Temp
Advisory High Temperature alarm set point. When the product temperature exceeds this
point an advisory alarm will be generated.
Adv Lo Level
Advisory Low Level alarm set point. When the product level drops below this point an
advisory alarm will be generated.
Adv Lo Temp
Advisory Low Temperature alarm set point. When the product temperature drops below
this point an advisory alarm will be generated.
Adv Rtd Level
Advisory Resistive Temperature Device Level. Height of the RTD in the tank. An alarm is
generated when the level goes below this level (temperature measurements can no
longer be made).
Advisory Alarms
Process alarms intended to act as caution indicators providing users advanced warnings
of unusual situations.
ATT
Varec Model 4000 Advanced Technology Transmitter.
ATTI Bus
Unpowered, non-intrinsically safe, HART compatible communication bus used on ATT.
Baud Rate
A communications measure of serial data transmission rate typically in bits per second.
Normal baud rates for RS-232 interfaces are 300, 1200, 2400, 4800, 9600, 19200. The
higher the baud rate, the faster the data transfer occurs across the data line.
Comm Port
Communication Port. An access point for data entry or exit.
Crit Hi Level
Critical High Level alarm set point. When the product level exceeds this point a critical
alarm is generated.
Crit Hi Temp
Critical High Temperature alarm set point. When the product temperature exceeds this
point a critical alarm is generated.
Crit Lo Level
Critical Low Level alarm set point. When the product level drops below this point a
critical alarm is generated.
Crit Lo Temp
Critical Low Temperature alarm set point. When the product temperature drops below
this point a critical alarm is generated.
