Terms and
Abbrevia-
tions
The following terms and abbreviations are used throughout this manual. For definitions of terms
not listed here refer to
Allen-Bradley’s Industrial Automation Glossary
, Publication ICCG-7.1.
Calibration
- Procedure, performed by trained personnel, where machine or press is
dynamically loaded to impact on load cells. A process of linearity measuring to determine the
loading capacity of the machine.
Calibration Number
- Amplification values established during machine calibration or pre-
assigned on force load cells.
Channel
- Refers to one of two, strain gage inputs available on the modules terminal block.
Chassis
- A hardware assembly that houses devices such as I/O modules, adapter modules,
processor modules, and power supplies.
Configuration Word
- Contains the channel configuration information needed by the module to
configure and operate each channel. Information is written to the configuration word through
the logic supplied in your ladder program.
Data Word
- A 16-bit integer that represent the value of the analog input channel. The channel
data word is valid only when the channel is enabled.
Gain
- Amplification of an input signal.
Load/Force -
Measurement of impact during a machine cycle. Sensors provide the input for
this measurement.
Look Window
- Resolver or cam activated window, which allows specific degrees in a machine
cycle to be processed.
Low Alarm Inhibit
- Number of consecutive machine cycles where low alarm is inhibited. Used
in a process where machine cycles several times before running speed is established.
LSB
- (Least Significant Bit) Refers to a data increment defined as the full scale range divided
by the resolution. The bit that represents the smallest value within a string of bits.
Monitor Parts Mode
- Status condition used during production run. Sample and compare logic
is enabled. On resolver based systems, tracking alarm limits can be enabled.
Multiplexer
- A switching system that allows several input signals to share a common A/D
converter.
Remote Configuration
- A control system where the chassis can be located several thousand
feet from the processor chassis.
