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, and 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-320
Position module.
Strobe
See Bit-Strobe.
transducer
A transducer is a device for taking measurements. These include
accelerometers, velocity pickups, displacement probes, and temperature
sensors.
trend
A set of records of one or more measurement parameter(s) collected at regular
intervals of a base parameter such as time.
trigger
An event that prompts the collection of trend data.
triggered trend
A time-base trend that is collected in an XM module when a relay on the
module is activated, or when the module receives a trigger event.
