Parameter Description
Show in Overview
For HART devices, primary measured value is always in the overview
• Check the box to show the secondary (SV), tertiary (TV) and quadrenary (QV) values
• Other inputs are enabled in the dialogs Analog Input Setup and Digital Input Setup
Description
2x 20 characters for user description of measured value
Actual Value
Read only parameter showing current measured value with date and time
Limit Status
Read only parameter showing the limit status with date and time
– OK: device is operating correctly
– HH, H, L, LL: value has exceeded or dropped below associated limit value
Note: The limit status applies to the limit values set in the web server. It has nothing to do with
any limits set within the device itself
min. Value
max. Value
Sets min. and max. range values in the web server
– These values are read by Fieldgate viewer for the bar chart and trend displays.
They must correspond to the values set in the device if 100% correspondance is required
Limit settings
Sets four limits in the web server for the parameter concerned:
– HH: High high limit, an alarm is set when measured value moves above the high high limit
– H: High limit, an alarm is set when the measured value moves above the high limit
– L: Low alarm, an alarm is set when the measured value moves below the low limit
– LL: Low low alarm, an alarm is set when the measured value moves below the low low limit
The status is flagged in the Limit Status column. If no value is entered, the limit is disabled.
Hysteresis limit
Gradient limit
Sets a hysteresis band in percent of set range and a rate of change limit in absolute units
– The hysteresis is set below HH and H limits and above L and LL limits. When a measured value
violates a limit, an alarm is immediately set. When it returns to within limits, the alarm is reset
only when the value leaves the hysteresis band.
– An alarm is sent when the rate of change of the measured value (in engineering units) is greater
than or equal to the set value
Mail on ...
Check the box to send an e-mail
• LIMIT: alarm is sent when the limit is violated
• RESET: alarm is sent when the value returns within limits, see Table 6-9
Show Switch...
For digital inputs, sets value, below /above which the text selected from the drop-down menu is
displayed.
– Switch level: enter limit level, e.g. 0, 1
– Switch status: select associated text
