Description
ACK_OPTION 38 Selection of whether alarms associated with the function block will be
automatically acknowledged.
ADVISE_ACTIVE 82 Enumerated list of advisory conditions within a device.
ADVISE_ALM 83 Alarm indicating advisory alarms. These conditions do not have a direct impact on the
process or device integrity.
ADVISE_ENABLE 80 Enabled ADVISE_ALM alarm conditions. Corresponds bit for bit to the ADVISE_ACTIVE.
A bit on means that the corresponding alarm condition is enabled and will be detected. A
bit off means the corresponding alarm condition is disabled and will not be detected.
ADVISE_MASK 81 Mask of ADVISE_ALM. Corresponds bit of bit to ADVISE_ACTIVE. A bit on means that
the condition is masked out from alarming.
ADVISE_PRI 79 Designates the alarming priority of the ADVISE_ALM
ALARM_SUM 37 The current alert status, unacknowledged states, unreported states, and disabled states
of the alarms associated with the function block.
ALERT_KEY 04 The identification number of the plant unit.
BLOCK_ALM 36 The block alarm is used for all configuration, hardware, connection failure or system
problems in the block. The cause of the alert is entered in the subcode field. The first alert
to become active will set the Active status in the Status parameter. As soon as the
Unreported status is cleared by the alert reporting task, another block alert may be
reported without clearing the Active status, if the subcode has changed.
BLOCK_ERR 06 This parameter reflects the error status associated with the hardware or software
components associated with a block. It is a bit string, so that multiple errors may be
shown.
CLR_FSTATE 30 Writing a Clear to this parameter will clear the device FAIL_SAFE if the field condition has
cleared.
CONFIRM_TIME 33 The time the resource will wait for confirmation of receipt of a report before trying again.
Retry will not happen when CONFIRM_TIME=0.
CYCLE_SEL 20 Used to select the block execution method for this resource. The 644 supports the
following:
Scheduled: Blocks are only executed based on the function block schedule.
Block Execution: A block may be executed by linking to another blocks completion.
CYCLE_TYPE 19 Identifies the block execution methods available for this resource.
DD_RESOURCE 09 String identifying the tag of the resource which contains the Device Description for
this resource.
DD_REV 13 Revision of the DD associated with the resource - used by an interface device to locate
the DD file for the resource.
DEFINE_WRITE_LOCK 60 Allows the operator to select how WRITE_LOCK behaves. The initial value is “lock
everything”. If the value is set to “lock only physical device” then the resource and
transducer blocks of the device will be locked but changes to function blocks will be
allowed.
DETAILED_STATUS 55 Indicateds the state of the transmitter. See Resource Block detailed status codes.
DEV_REV 12 Manufacturer revision number associated with the resource - used by an interface device
to locate the DD file for the resource.
DEV_STRING 43 This is used to load new licensing into the device. The value can be written but will always
read back with a value of 0.
DEV_TYPE 11 Manufacturer’s model number associated with the resource - used by interface devices to
locate the DD file for the resource.
DIAG_OPTIONS 46 Indicates which diagnostics licensing options are enabled.
DISTRIBUTOR 42 Reserved for use as distributor ID. No Foundation enumerations defined at this time.
DOWNLOAD_MODE 67 Gives access to the boot block code for over-the-wire downloads.
0 = Uninitialized
