Static Process Variable Data
Process Variable (PV) or direct data is used to trend the overall vibration and temperature. PV data can
be sent to System 1 through GCI, HART-IP, Modbus or OPC. PV data sent by GCI conforms to the ISA100,
foundation fieldbus standard. Data sent by HART-IP conforms to the HART standard.
For ISA100 devices PV data is timestamped by the gateway and not at the time of acquisition.
WirelessHART device PV data is timestamped by the device at the time of acquisition.
A user can select the units, sub-units, time interval, Fmin and Fmax settings..

Dynamic Data
Dynamic data is measured at the interval and start date/time set by the user. You can select the number
of samples, Fmin, Fmax, and time interval. Dynamic data is collected sequentially for each measurement
axis and time stamped when the data collection occurs.
