5.2.1 Parameters of Resource Block
Relative
index
Parameter name R/W Data format Description
0 （ Block Header ） Information about this block
1 ST_REV R TYPE_U16/2
The revision level of the static data associated with the function block. The revision
value will be incremented each time a static parameter value in the block is changed.
2 TAG_DESC W TYPE_OCT_STRING/32 A parameter to describe a comment about the content of the tag
3 STRATEGY W TYPE_U16/2
A parameter available for high-level system to group or identify the
function block. This data is not checked or processed by the block.
4 ALERT_KEY W TYPE_U8/1
Identification number of the plant unit. This information may be
used for sorting alarms, etc.
5 MODE_BLK.TARGET W TYPE_ENUM/1
A parameter to set the mode of function block. Only one of the
supported modes can be selected.
6 MODE_BLK.ACTUAL R TYPE_ENUM/1
The current mode of the block. (May differ from TARGET based
on operating conditions.)
7 MODE_BLK.PERMITTED W TYPE_ENUM/1 This is the mode supported by the function block.
8 MODE_BLK.NORMAL W TYPE_ENUM/1 This is the mode set at normal operation condition.
9 BLOCK_ERR R TYPE_ENUM/2
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.
10 UPDATE_EVT.UNACKNOWLEDGED W TYPE_ENUM/1 This parameter describes the event when an update occurs.
11 UPDATE_EVT.UPDATE_STATE W TYPE_ENUM/1 This parameter indicates whether an update event has been reported.
12 UPDATE_EVT.TIME_STAMP R TYPE_TIME/8 This parameter indicates the time of occurrence of an update event.
13 UPDATE_EVT.STATIC_REVISION R TYPE_U16/2 This parameter indicates the number of occurrence of an update event.
14 UPDATE_EVT.RELATIVE_INDEX R TYPE_U16/2 This parameter indicates the relative index of an update event.
15 BLOCK_ALM.UNACKNOWLEDGED W TYPE_ENUM/1
This parameter describes the alarm when a block alarm occurs.
16 BLOCK_ALM.ALARM_STATE R TYPE_ENUM/1
17 BLOCK_ALM.TIME_STAMP R TYPE_TIME/8
18 BLOCK_ALM.SUB_CODE R TYPE_ENUM/2
19 BLOCK_ALM.VALUE R TYPE_U8/1
