Read Write
Description: The user description of the intended
application of the block
MODE_BLK
[Process]
[Diagnostic]
Description: The actual target, permitted, and normal
modes of the block.
PV_D
[Process]
Description: Either the primary discrete value for use
in executing the function or a process value
associated with it. May also be calculated from the
READBACK_D value of a DO block.
SP_D
[Process]
Description: The discrete set point of this block.
OUT_D
[Process]
Description: The primary discrete value calculated as
a result of executing the function block.
XD_STATE
[Process]
Description: Index to the text describing the states of
a discrete for the value obtained from the transducer.
CAS_IN_D
[Process]
Description: This parameter is the remote set point
value of a discrete block, which must
come from another Fieldbus block, or a DCS block
through a defined link.
CHANNEL
[Process]
Description: The number of logical hardware channel
that is connected to this I/O block. This information
defines the transducer to be used going to or from the
physical unit.
RCAS_IN_D
[Process]
Description: Target set point and status provided by a
supervisory Host to a discrete
control or output block.
RCAS_OUT_D
[Process]
Description: Block set point and status provided to a
supervisory Host for back calculation and to allow
action to be taken under limiting conditions or mode
change.
READBACK_D
[Tuning]
Description: This indicates the read back of the
actual discrete valve or other actuator position, in the
transducer state.
SIMULATE_D
[Options]
Description: Allows the transducer discrete input or
output to the block to be manually supplied when
simulate is enabled. When simulation is disabled, the
simulate value and status track the actual value and
status.
GRANT_DENY
[Options]
Description: Options for controlling access of host
computer and local control panels to operating,
tuning and alarm parameters of the block.
IO_OPTS
[Options]
Description: Options which the user may select to
alter input and output block processing.
STATUS_OPTS
[Options]
Description: Options which the user may select in the
block processing of status.
FSTATE_TIME
[Options]
Description: The time in seconds from detection of
fault of the output block remote set point to the
output action of the block output if the condition still
