RESOURCE BLOCK

PARAMETERS

Table C-1. Resource Block Parameters

Number	Parameter	Description
1	ST_ REV	The revision level of the static data associated with the function block.
2	TAG_ DESC	The user description of the intended application of the block.
3	STRATEGY	The strategy field can be used to identify grouping of blocks.
4	ALERT_ KEY	The identification number of the plant unit.
5	MODE_ BLK	The actual, target, permitted, and normal modes of the block. For further description, see the Mode
		parameter formal model in FF-890.
6	BLOCK_ ERR	This parameter reflects the error status associated with the hardware or software components associated
		with a block. Multiple errors may be shown. For a list of enumeration values, see FF-890, Block_ Err
		formal model.
7	RS_ STATE	State of the function block application state machine. For a list of enumeration values, see FF-890.
8	TEST_ RW	Read/write test parameter - used only for conformance testing.
9	DD_ RESOURCE	String identifying the tag of the resource which contains the Device Description for the resource.
10	MANUFAC_ ID	Manufacturer identification number - used by an interface device to locate the DD file for the resource.
11	DEV_ TYPE	Manufacturer's model number associated with the resource - used by interface devices to locate the DD
		file for the resource.
12	DEV_ REV	Manufacturer revision number associated with the resource - used by an interface device to locate the DD
		file for the resource.
13	DD_ REV	Revision of the DD associated with the resource - used by the interface device to locate the DD file for the
		resource.
14	GRANT_ DENY	Options for controlling access of host computer and local control panels to operating, tuning and alarm
		parameters of the block.
15	HARD_ TYPES	The types of hardware available as channel numbers. The supported hardware type is: SCALAR_ INPUT
16	RESTART	Allows a manual restart to be initiated.
17	FEATURES	Used to show supported resource block options. The supported features are: SOFT_ WRITE_ LOCK_
		SUPPORT, HARD_ WRITE_ LOCK_ SUPPORT, REPORTS, and UNICODE
18	FEATURE_ SEL	Used to select resource block options.
19	CYCLE_ TYPE	Identifies the block execution methods available for this resource. The supported cycle types are:
		SCHEDULED, and COMPLETION_ OF_ BLOCK_ EXECUTION
20	CYCLE_ SEL	Used to select the block execution method for this resource.
21	MIN_ CYCLE_T	Time duration of the shortest cycle interval of which the resource is capable.
22	MEMORY_ SIZE	Available configuration memory in the empty resource. To be checked before attempting a download.
