Alarm Handling)
Alert Key
Alert Key (ALERT_KEY [4]) is a number that permits
grouping alerts. This number may be used to indicate
to the operator the source of the alert, such as the
instrument, plant unit, etc. Enter a value between 1
and 255.
Confirm Time
Confirm Time (CONFIRM_TIME [33]) determines the
time, in 1/32 of a millisecond, the instrument waits for
confirmation of receipt of a report before trying again.
If Confirm Time is 0, the instrument does not retry to
send the report. Enter 0 or a value between 320000
(10 secs) and 640000 (20 secs).
Limit Notify
Limit Notify (LIM_NOTIFY [32]) is the number of alert
reports that the device can send without getting a
confirmation up to the maximum permitted in
Maximum Notify (MAX_NOTIFY [31]). If Limit Notify is
set to zero, no alerts are reported. Enter a value
between 0 and 3.
To have the instrument report alerts without having the
host poll the alerts parameters, select the Reports
feature (see Feature Select).
Maximum Notify
Maximum Notify (MAX_NOTIFY [31]) indicates the
maximum number of alert reports that the device can
send without getting a confirmation. This limit is
determined by the amount of memory available for
alert messages. The number can be set lower, to
control alert flooding, by adjusting Maximum Alerts
Allowed (LIM_NOTIFY [32]).
Block Alarm Disabled
The Block Alarm (BLOCK_ALM [36]) is used for all
configuration, hardware, connection failure or system
problems in the block. Alarm Summary (ALARM_SUM
[37]) determines if the Write Alarm (WRITE_ALM [40])
and Block Alarm [BLOCK_ALM [36]) are disabled.
Block Alarm Auto Acknowledge
Acknowledge Option (ACK_OPTION [38]) determines
if the block alarm will be automatically acknowledged.
Discrete Alarm Disabled
The Write Alarm (WRITE_ALM [40]) is used to alert
when parameters are writeable to the device. Alarm
Summary (ALARM_SUM [37]) determines if the
Discrete Alarm is disabled.
Discrete Alarm Auto Acknowledge
Acknowledge Option (ACK_OPTION [38]) determines
if the Write Alarm associated with the block will be
automatically acknowledged.
Identification
(RB

Identification)
Device ID
The 32 character Device ID (DEVICE_ID [54]).
Electronics Serial Number
The Electronics Serial Number (ELECTRONICS_SN
[49]) set at the factory.
Factory Serial Number
The Factory Serial Number (FACTORY_SN [50]) is
the instrument serial number set at the factory.
Field Serial Number
The Field Serial Number (FIELD_SN [51]) is the serial
number of instrument assigned in field.
Tag Description
The Tag Description (TAG_DESC [2]) is used to
assign a unique 32 character description to each block
within the digital valve controller to describe the
intended application for the block.
Strategy
Strategy (STRATEGY [3]) permits strategic grouping
of blocks so the operator can identify where the block
is located. The blocks may be grouped by plant area,
plant equipment, etc. Enter a value between 0 and
65535 in the Strategy field.
Manufacturer
Manufacturer Identification (MANUFAC_ID [10])
identifies the manufacturer of the instrument. It is used
by the host system to locate the DD file for the device.
For Fisher the Manufacturer ID is 0x5100.
Device Type
Device Type (DEV_TYPE [11]) identifies the type of
device. It is used by the host system to locate the DD
file for the device. For a DVC6000f digital valve
controller the device type is 0x4602.
Diagnostics Options
Diagnostic Options (DIAG_OPTIONS [45]) shows the
diagnostic options available in the instrument.
