Parameter Description
Writing a Clear to this parameter will clear the device FAIL_SAFE if the field
condition has cleared.
Maximum number of unconfirmed notify messages possible.
Maximum number of unconfirmed alert notify messages allowed.
The time the resource will wait for confirmation of receipt of a report before trying
again. Retry will not happen when CONFIRM_TIME=0.
When hardware write protection is selected, WRITE_LOCK becomes an indicator of
the jumper setting and is unavailable for software write protection.
When software write lock is selected, and WRITE_LOCK is set, no writings from
anywhere else are allowed, except to clear WRITE_LOCK. Block input will continue
to be updated.
This alert is generated by any change to the static data.
The block alarm is used for all configuration, hardware, connection failure or
system problems in the block. The cause of the alarm is entered in the subcode
field. The first alarm to become active will set the Active status in the Status
parameter. As soon as the Unreported status is cleared by the alarm reporting task,
another block alarm may be reported without clearing the Active status, if the
subcode has changed.
The current alarm status, unacknowledged states, unreported states, and disabled
states of the alarms associated with the function block.
Selection of whether alarms associated with the function block will be
automatically acknowledged.
Priority of the alarm generated by clearing the write lock.
This alert is generated if the write lock parameter is cleared.
Major revision number of the inter operability test case used in certifying this
device as interoperable. The format and range are controlled by the Fieldbus
Foundation.
A parameter equal to the value of the major version of the Field Diagnostics
specification that this device was designed to.
This parameter reflects the error conditions that are being detected as active as
selected for this category. It is a bit string, so that multiple conditions may be
shown.
This parameter maps conditions to be detected as active for this alarm category.
Thus the same condition may be active in all, some, or none of the 4 alarm
categories.
This parameter allows the user to suppress any single or multiple conditions that
are active, in this category, from being broadcast to the host through the alarm
parameter. A bit equal to '1' will mask i.e. inhibit the broadcast of a condition, and a
bit equal to '0' will unmask i.e. allow broadcast of a condition.
