Advanced Features
Additional advanced features are also available that can be enable or disabled at user discretion. These
features apply both ISA100 and WirelessHART VP Series 2000 sensors and can be set using the
configuration software either during configuration or over the air as required.
Data on Demand
Acquire data within 8 to 10 minutes upon request using the configuration software. Data on demand
requests cancel the most recently acquired scheduled measurements if they are still being transferred
to the gateway. Subsequent scheduled measurements are delayed by 90 minutes after a data on
demand request.
Data on Vibration
Data on vibration is a threshold based scheduled data collection. The user sets a vibration threshold
which must be exceeded to enable overall or dynamic measurement acquisition. This is useful for low
vibration or machines that are not running.
• If vibration is below the threshold, overall values are published as zero and dynamic
measurement transfers are skipped.
• If vibration is above the threshold, data is published and transferred as configured.
Data on Severity
Data is acquired depending on the severity of the vibration level as compared to user defined limits. The
severity levels have been defined as follows:
• Green
o Vibration is below defined limits.
o Data is collected at the configured interval.
• Yellow
o Vibration is between the lower and upper defined limits.
o Acquire a dataset immediately.
o Revert to collecting data at the configured interval.
• Red
o Vibration is above the upper defined limit.
o Acquire a dataset immediately.
o Set overall measurements to be taken at the shortest allowed interval (10 minutes).
o Set dynamic measurements to be taken at the shortest allowed interval (6 hours).
