Software features

The following features are available in the Rosemount
software.
• Alert History: Displays latched device status alerts issued due to errors and warnings.
You may clear latched status alerts manually by using the Clear Alert History
command, by resetting the deivce, by cycling device power, or by changing device
configuration settings.
• Clear Alert History: Manually clears the alerts displayed in Alert History. You cannot
clear active alerts. You can also clear alert history by resetting the device or cycling
device power.
• Process Alerts: Up to eight process alerts are available to trigger alerts when device
variables exceed the configured alert threshold.
• Sensor Module Information: Information about the installed sensor module includes
gas name, gas module type, serial number, date of manufacture, hardware revision
level, software revision level, gas module compatibility revision level, and minimum
feature board compatibility revision level. This is useful for review and tracking.
• Service Reminders: If selected, displays reminders when the installed gas sensor
module is due for service based on the specified service date (the date on which the gas
sensor module was last calibrated).
• Calibration History: Displays the calibration history of the installed gas sensor module.
• Gas Module Replacement: Displays a notification that the gas sensor module must be
replaced soon. This can only be resolved by replacing the gas sensor module.
• Revert to Previous Gas Module Calibration: Restores the previously-stored gas module
calibration settings. This is useful when a gas calibration result is unsatisfactory. You
cannot successfully execute this command if the most recent calibration has been
stored to history or if the device has been reset.
• Store Calibration to History: Stores the current gas module calibration settings in the
calibration history log. Once you have executed this command or reset the device,
reverting to the previous calibration is impossible.
• Local Alarm Output: If the device is equipped with this option, an external power
supply and alert mechanism issue a local alarm when the detected gas concentration
level exceeds the specified High Concentration Threshold. You can configure the local
alarm to latch the alarm output until the alarm is manually cleared. Latched alarms do
not remain latched following a device reset or power module failure. You may query
the device to detect whether this option is installed. Examples of alarm mechanism
options include:
—

Verify that gas concentrations in the area have dissipated to a safe level before clearing
local or digital alarms.
• Gas Concentration Alarm Configuration: Displays the configuration settings for local
and digital gas concentration alarms when the detected gas concentration level
