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_
DIRECTORY
A directory that specifies the number and starting indices of the transducers in the transducer block. For
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_
DIRECTORY
A directory that specifies the number, starting indices, and DD item IDs of the data collections in each
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_
SAFE
When the device detects a failure, IO1 will have its value set to this value.
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_
SAFE
When the device detects a failure, IO2 will have its value set to this value.
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_
SAFE
When the device detects a failure, IO3 will have its value set to this value.
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_
SAFE
When the device detects a failure, IO4 will have its value set to this value.
