Output OUT C102 0 When in Auto, this is the actual result of the controller
PID algorithm; otherwise, it is the value determined by
the output pushbuttons. it is transferred to ANO0.
Alarm
Limit 1 PL1 C103 100 This parameter is the point in engineering units at which
the upper alarm is triggered.
Alarm
Limit 2 PL2 C104 0 This parameter is the point in engineering units at which
the lower alarm is triggered.
Alarm
Dead Band ADB C105 2 This parameter sets the activation/deactivation gap for
the alarm. This value in engineering units defines an area
of hysteresis at the alarm point.
Proportional
Band PB C106 100 This parameter is the percent of error required to move
the output full scale for proportional action. It modifies the
controller response in standard PID terms.
Reset Time TR C107 0 This parameter represents the number of minutes per
repeat for integral action. It modifies the controller
response in standard PID terms.
Rate Time TD C108 0 This parameter represents the minutes that proportional
action is advanced (derivative action).
Manual
Reset
MR C111 50
This parameter determines the position of the valve
(output) when the instrument is in Automatic mode and
the error is zero. (It is only in effect when TR = 0.)
Controller
Span
IR C115 100
These two parameters set the upper and lower values on
the controller display. They permit the control action to be
defined over a range independent of the process variable
input range. They also determine the speed at which the
setpoint changes when the
U P or D OWN arrow pushbuttons
are pressed (CS1 through CS3).
For CS4, they determine only the displayable range, as
the setpoint pushbuttons are not used.
Controller
Lower
Range ILR C116 0
Remote
Setpoint RSP C120 0 It is the calculated result of the remote setpoint algorithm
and is used as the setpoint if the controller is in remote.
ANI0
Engineering
Span SPAN C256 100 This determines the upper range that analog input 0
represents in engineering units. The upper range value
equals Engineering Zero plus Engineering Span.
ANI1
Engineering
Span
SPAN C257 100
This determines the upper range that analog input 1
represents in engineering units. The upper range value
equals Engineering Zero plus Engineering Span.
ANI0
Engineering
Zero ZERO C276 0 This is the lower range value of analog input 0.
