Parameter
Description
Show in Overview
Checking this box causes the parameters in the associated line to be shown in the overview of
devices
Point Name
Read only parameter from device showing Block name and Measuring Tag (if configured)
– These parameters are read from the device and cannot be changed from the web server
Current Value and
Status
Read only parameter showing the current measured value and status of the measuring point
– OK: device is operating correctly
– UNCERTAIN: device is operating, but the status of the output value is uncertain, e.g. because
a limit value within the device has been violated
– BAD: the device has detected a fault, e.g. sensor failure
(based on PA Profile 3.0, Chapter 3.11.4)
Limit Status
Read only value showing whether the associated value is within the alarm limits set in the web
server for this parameter:
– OK: within alarm limits
– HH: High high alarm, the measured value is above the high high limit
– H: High alarm, the measured value is above the high limit but below the high high limit
– L: Low alarm, the measured value is below the low limit but above the low low limit
– LL: Low low alarm, the measured value is below the low low limit
– EDIT!: The limits set in the Web server and the range in the parameter description are not
consistant.
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
Limit
Allows four limits to be set in the web server on 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.
Note: These limits are applied by the Fieldgate to the value it reads from the connected device.
These limits have nothing to do with those that can be set within the device itself
Hysteresis
Allows a hysteresis band in percent of set range to be 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.
E-mail on alarm
Allows the response to an alarm event to be set. Check the options as appropriate:
– SET: when checked will cause an e-mail to be sent on violation of a limit
– RST: when checked will cause an e-mail to be sent when the value returns to normal
The e-mail set up is described in Section 6.6.2, the alarm status table in Table 6-7.
