Description
Data Type: DS‐69
Valid Bits: 7: OOS, 6: IMAN, 5: LO, 4: MAN, 3: AUTO,
2: CAS, 1: RCAS
The actual, target, permitted, and normal modes of
the block.
Target: The requested block mode
Actual: The current mode of the block
(Note: Bit 6 (IMAN) is valid for ACTUAL only)
Permitted: Allowed modes for Target
Normal: Most common mode for Target
Data Type: Bit String (2 byte)
0=inactive
1=active
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. See table E‐1.
Data Type: DS‐65
The process variable used in block execution. This
value is converted from READBACK to show the
actuator position in the same units as the setpoint
value.
Data Type: DS‐65
The SP of the analog block. Can be derived from
CAS_IN, RCAS_IN in normal modes, or can track PV
in MAN, IMan or LO modes. IO_OPTS is used to
determine value of SP in MAN, IMan or LO. If no
IO_OPTS for SP tracking are set, SP will freeze when
mode changes from CAS or RCAS.
Data Type: DS‐65
The primary value and status calculated by the
block in Auto mode. OUT may be set manually in
Man mode.
Data Type: DS‐82
Allows the analog input to be manually supplied
when simulate is enabled. When simulation is
disabled, the simulate value and status track actual
value & status.
Data Type: DS‐68
The high and low scale values, engineering units
code, and number of decimal places to be used in
displaying the PV parameter and parameters which
have the same scaling as PV.
Data Type: DS‐68
The high and low scale values and engineering
units code are read only. This parameter
determines the number of digits to the right of the
decimal point used with the value obtained from
the transducer for a specified channel.
