Glossary 114
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.
settling time
The amount of time it takes a measurement to reach 90% of the final value
given a step change in the input signal.
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-220
Dual Speed module.
transducer
A transducer is a device for making measurements. These include
accelerometers, velocity pickups, displacement probes, and temperature
sensors.
virtual relay
A virtual relay is a non-physical relay. It has the same capabilities (monitors
alarms, activation delay, change status) as a physical relay only without any
physical or electrical output. The virtual relay provides additional relay status
inputs to a controller, PLC, or an XM-440 Master Relay module (firmware
revision 5.0 and later).
XM configuration
XM configuration is a collection of user-defined parameters for XM modules.
XM Serial Configuration Utility software
XM Serial Configuration Utility software is a tool for monitoring and
configuring XM modules. It can be run on computers running Windows 2000
service pack 2, Windows NT 4.0 service pack 6, or Windows XP operating
systems.
