PARAMETERS

Table C-2. I/O Transducer Parameters

Numbe
r	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	UPDATE_ EVT	This alert is generated by any change to the static data.

8	BLOCK_ ALM	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 attribute. 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.
9	TRANSDUCER_	A directory that specifies the number and starting indices of the transducers in the transducer block. For
	DIRECTORY	further information, please refer to the Transducer Block Application Process - Part 1 (FF-902)
		specification.

10	TRANSDUCER_ TYPE	Identifies the transducer that follows.
11	XD_ ERROR	One of the error codes defined in FF-903 XD_ ERROR and Block Alarm Subcodes.

12	COLLECTION_	A directory that specifies the number, starting indices, and DD item IDs of the data collections in each
	DIRECTORY	transducer within a transducer block. For further information, please refer FF-902.
13	IN_ 1_ TAG	An identifier associated with discrete input 1.

14	IN1	The value and status of discrete input 1.
15	PULSE_ COUNT_ 1	The number of pulses that have occurred on IN1 since last reset.

16	IN_ 1_ CONFIG.IO_TYPE	The transducer type of discrete sensor 1.
16	IN_ 1_ CONFIG.FILTER	Any state change on IN1 that lasts for a duration less than this filter value, will be ignored by the device.

16	IN_ 1_ CONFIG.FAIL_	When the device detects a failure, IO1 will have its value set to this value.
	SAFE
17	IN_ 2_ TAG	An identifier associated with discrete input 2.

18	IN2	The value and status of discrete input 2.
19	PULSE_ COUNT_ 2	The number of pulses that have occurred on IN2 since last reset.

20	IN_ 2_ CONFIG.IO_TYPE	The transducer type of discrete sensor 2.
20	IN_ 2_ CONFIG.FILTER	Any state change on IN2 that lasts for a duration less than this filter value, will be ignored by the device.

20	IN_ 2_ CONFIG.FAIL_	When the device detects a failure, IO2 will have its value set to this value.
	SAFE
21	IN_ 3_ TAG	An identifier associated with discrete input 3.

22	IN3	The value and status of discrete input 3.
23	PULSE_ COUNT_ 3	The number of pulses that have occurred on IN3 since last reset.

24	IN_ 3_ CONFIG.IO_TYPE	The transducer type of discrete sensor 3.
24	IN_ 3_ CONFIG.FILTER	Any state change on IN3 that lasts for a duration less than this filter value, will be ignored by the device.

24	IN_ 3_ CONFIG.FAIL_	When the device detects a failure, IO3 will have its value set to this value.
	SAFE
25	IN_ 4_ TAG	An identifier associated with discrete input 4.

26	IN4	The value and status of discrete input 4.
27	PULSE_ COUNT_ 4	The number of pulses that have occurred on IN4 since last reset.

28	IN_ 4_ CONFIG.IO_TYPE	The transducer type of discrete sensor 4.
28	IN_ 4_ CONFIG.FILTER	Any state change on IN4 that lasts for a duration less than this filter value, will be ignored by the device.

28	IN_ 4_ CONFIG.FAIL_	When the device detects a failure, IO4 will have its value set to this value.
	SAFE
