Instruction Manual
Description
Data Type: DS‐70
Options for controlling access of host computer and
local control panels to operating, tuning, and alarm
parameters of the block.
GRANT: 0=N/A, 1=granted
DENY: 0=N/A, 1=denied
Data Type: Bit String
0=Disable
1=Enable
User options for Output Control.
Data Type: Bit String

User options for Status
Data Type: Unsigned16
Used to select the type of threshold that is used to
set the output.
Data Type: Enum
Linearization type. Determines whether the field
value is used directly (Direct), is converted linearly
(Indirect), or is converted with the square root
(Indirect Square Root). The OUT_SCALE is normally
the same as the transducer, but if L_TYPE is set to
Indirect or Ind Sqr Root, OUT_SCALE determines the
conversion from FIELD_VAL to the output.
Data Type: Float
If calculated output is below this value the output is
0.
Data Type: Float
Time constant of first order filter on PV, in seconds.
Data Type: DS‐65
Value of the field device analog input, with a status
reflecting the Transducer condition.
Data Type: DS‐73
This alarm is generated whenever a static parameter
is changed.
Data Type: DS‐72
The block alarm is used for all configuration,
hardware, connection failure or system problems in
the block. The cause of the alert is entered in the
subcode field.
