Information on this block such as Block Tag, DD Revision,
Execution Time etc.
The revision level of the static data of the DI block. The
value of this parameter is incremented each time a static
parameter value is changed. Valid range is 0 to 65535.
The user description of the intended application of the block
Used by an upper-level system to identify grouping of the
block. Not checked or processed by the block. Valid range
is 0 to 65535.
The identification number of the plant unit. This information
may be used in the host for sorting alarms, etc.
The actual, target, permitted and normal modes of the block.
Indicates the error statuses related to the block itself.
The primary discrete value (or process value) for execution
of the block's functions.
Indicates the value and status of block's output.
Allows use of values manually set instead of the limit switch
input from the transducer block. When Disable is set for
this value, the block reflects the actual input value and
status. 1: Disabled, 2: Active
Not used in AXF.
Not used in AXF.
Option to control access from the host computer and local
control panel to tuning and alarm parameters. Before write
access to a parameter, set the GRANT bit in this parameter
to have the operation right to be granted. Then after write
access, check the DENY bit in this parameter. If the write
access is successfully, it is not ON.
Sets the block input/output options. The AXF supports only
0: Invert (LSB).
Defines block actions depending on block status conditions.
For DI blocks of the AXF, 3: Propagate fault Forward,
8: Uncertain if Man mode are supported.
The channel number of the transducer block's logical
hardware channel connected to this block. Valid range is
2: LIMSW_1, 3: LIMSW_2, 4: SWITCH_1, 5: SWITCH_2
Sets the time constant of damping for PV_D.
The status of the limit switch signal transferred from the
transducer block.
