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-320
Position 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 (monitor
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, and XM-440 Master Relay module (firmware
revision 5 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 service pack 6, or Windows XP operating
systems.
