Parameters and Descriptions

The table below lists all of the configurable parameters of the Resource Block, including the descriptions and index numbers for each.

Table C-1. Resource Block Parameters and Descriptions

	Index
Parameter	Number	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
		1 = Run mode
		2 = Download mode
