The number of ampere-hours a cell/battery can deliver under specific
conditions (rate of discharge, cut-off voltage, temperature).
Natural gas that has not been processed.
A mixture of natural gas liquids that has not been fractionated or
separated into its various components.
Communication abbreviation for Results Bus.
Communication abbreviation for Received.
Acronym for Relative Density.
Refers to Totalflow's SRam Drive (solid state memory chip) located on
the main board, used to store data and configuration files. The RDrive
is a lithium backed, volatile memory chip and is not affected by a warm
start.
Computer memory in which data can be routinely read but written to
only once using special means when the ROM is manufactured. ROM
is used for storing data or programs (e.g. operating systems) on a
permanent basis.
Data acted upon immediately instead of being accumulated and
processed at a later time.
The SCADA system has an in-memory RTDB for the data it collects
from various devices. Real-time generally means that the data is
acquired often enough that the user can make operational changes to
the process while it is still useful to do so. On a factory floor, this can be
in milliseconds. For remote devices which may require a couple of
hours of drive time to reach, real-time can be thought of in tens of
minutes or even hours. The data base can meet either of these
requirements.
Any operating system where interrupts are guaranteed to be handled
within a certain specified maximum time, thereby making it suitable for
control of hardware in embedded systems and other time-critical
applications. RTOS is not a specific product but a class of operating
system.
The conversion of electrical energy, provided in the form of a current
from an external source (charger), into chemical energy within a
cell/battery.
This is the standard interface for full-duplex data communication
conducted with two way independent channels. It employs unbalanced
signaling and refers to point-to-point communications between one
driver and one receiver in a 4-wire bus system.
The RS-232 (single-ended) transmits at a relatively slow data rate (up
to 20K bits per second) and short distances (up to 50 Ft. @ the
maximum data rate).
