Glossary 198
orders
Multiples of the operating speed of a piece of equipment. The first order is the
operating speed. The second order is two times the operating speed, and so
on.
online help
Online help allows you to get help for your program on the computer screen
by pressing F1. The help that appears in the Help window is context sensitive,
which means that the help is related to what you are currently doing in the
program.
Polled
DeviceNet communications method in which module sends data in response
to a poll request from a master device.
Program mode
The XM module is idle. Typically this occurs when the module configuration
settings are being updated with the XM Configuration program. In Program
mode, the signal processing/measurement process is stopped. The status of
the alarms is set to the disarm state to prevent a false alert or danger status.
Run mode
In Run mode, the module collects measurement data and monitors each
measurement device.
setting time
The amount of time it takes a measurement to reach 90% of the final value
given a step change in the input signal.
signal detection
Defines the method of conditioning or measuring a dynamic input signal. Peak
(0 to the peak voltage), Peak-Peak (minimum peak to maximum peak), and
RMS (square root of the mean of the square of the values) are the most
common methods of signal detection.
slave device
A device that receives and responds to messages from a Master device but
does not initiate communication. Slave devices include the XM measurement
modules, such as the XM-120 Dynamic Measurement module and the XM-320
Position module.
