PID Function Block
Initial Value Description
100 Data Type: DS-68
0 The high and low scale values, engineering units
% code, and number of digits to the right of the
2 decimal point associated with OUT.
Data Type: DS-70
Options for controlling access of host computers
All bits: 0
and local control panels to operating, tuning, and
alarm parameters of the block. Not used by the
device.
GRANT: 0=N/A, 1=granted
DENY: 0 = N/A, 1= denied
All bits: 0
Data Type: Bit String
0=disable
All bits: 0
1=enable
Allows you to specify control strategy options.
Data Type: Bit String
0=disable
1=enable
All bits: 0
Allows you to select options for status handling
and processing.
BAD:
NC:
Data Type: DS-65
const
The primary input value of the block.
0
Data Type: Float
The time constant of the first−order PV filter. It is
0
the time, in seconds, required for a 63 percent
change in the IN value.
Data Type: Enum
Used to override the calculation of the block.
0=undefined
When enabled, the SP is sent directly to the
output.
BAD
NC:
Data Type: DS-65
const
The setpoint value from another block.
0
Data Type: Float
Ramp rate for downward SP changes. When the
+ INF
ramp rate is set to zero, the SP is used
immediately. PV per second
Data Type: Float
Ramp rate for upward SP changes. When the
+ INF
ramp rate is set to zero, the SP is used
immediately. PV per second
Data Type: Float
100
The highest SP value allowed.
Data Type: Float
0
The lowest SP value allowed.
