BLOCK_OBJECT
16 / 0
This object contains the characteristics of the blocks.
ST_REV
17 / 1
Revision counter for static variables. If a static variable changes its value, this counter is
incremented by one.
TAG_DESC
18 / 2
Every block can be assigned a textual TAG description.
The TAG_DESC must be unambiguous and unique in the Fieldbus system.
STRATEGY
19 / 3
The STRATEGY parameter has a user-specified value. This assigned value can be used
in configuration or diagnostics as a key in sorting block information.
ALERT_KEY
20 / 4
The ALERT_KEY parameter has a user-assigned value that can be used for sorting
alarms or events generated by a block.
TARGET_MODE
The TARGET_MODE indicates what mode of operation is required for the block. It is
normally set by a control application or by an operator through a human interface
21 / 5
application. The input parameters are used by the algorithm in conjunction with the state
of the Function Block application containing the block to determine if the algorithm can
achieve the target mode of operation established for it.
See parameter 'MODE_BLK', 'Permitted' element for possible values.
MODE_BLK
The MODE_BLK is a structured parameter composed of the actual mode, the normal
mode and the permitted mode of the block.
The actual mode is set (calculated) by the block during its execution to reflect the mode
used during execution.
22 / 6
Normal mode is the required operating mode of the block.
The permitted mode shows which changes of the target mode are valid for the specific
block to the remote user of the MODE_BLK parameter.
8: Auto
ALARM_SUM
23 / 7
The ALARM_SUM parameter summarizes the status of up to 16 block alarms. For each
alarm, the current states, unacknowledged states, unreported states and disabled states
are maintained.
VOLUME_FORWARD
24 / 8
Volume forward totalizer.
Unit: TB3.VOLUME_AND_PULSE_UNIT
VOLUME_REVERSE
25 / 9
Volume reverse totalizer.
Unit: TB3.VOLUME_AND_PULSE_UNIT
VOLUME_NET
26 / 10
Volume net totalizer.
Unit: TB3.VOLUME_AND_PULSE_UNIT
RESET_VOLUME_FORWARD
27 / 11
Resets the volume forward totalizer.
RESET_VOLUME_REVERSE
28 / 12
Resets the volume reverse totalizer.
RESET_VOLUME_NET
29 / 13
Resets the volume net totalizer.
