114

Get/Set

Proportional Band Cool
Temperature

UDINT

Set the proportional band for
the Cool outputs.

1 to 999°C (* 1000), if
Sensor Type is set to
Thermocouple or RTD.

(default = 25°C)

115

Get/Set

Proportional Band Cool
Process

UDINT

Set the proportional band for
the Cool outputs.

0.001 to 999.999 units, if
Sensor Type is set to mA
or Volt.

(default = 25.000 units)

116

Get/Set

Integral Cool

UDINT

Set the PID integral in minutes
per repeat for the Cool out-
puts.

0.00 to 99.99 (* 1000)
minutes per repeat.

0.00 = disabled

(default = 0.00)

116

Get/Set

Reset Cool

UDINT

Set the PID reset in repeats
per minute for the Cool out-
puts.

0.00 to 99.99 (* 1000)
repeats per minute.

0.00 = disabled

(default = 0.00)

117

Get/Set

Derivative Cool

UDINT

Set the PID derivative time
in minutes for the Cool out-
puts.

0.00 to 9.99 (* 1000)
minutes
0.00 = disabled
(default = 0.00)

117

Get/Set

Rate Cool

UDINT

Set the PID rate time in min-
utes for the Cool output.

0.00 to 9.99 (* 1000)
minutes
0.00 = disabled
(default = 0.00)

118

Get/Set

Dead Band Cool

UDINT

An offset of the Cooling pro-
portional band from the set
point.

0 to 999 (* 1000)

(default = 0)

119

Get/Set

Cool Hysteresis
Temperature

UDINT

Set the control switching hys-
teresis for ON/OFF control.
This determines how far into
the ON region the input needs
to move before the output
actually turns on.

1 to 999 (* 1000)
degrees, if Sensor Type is
set to Thermocouple or
RTD

(default = 1.0)

120

Get/Set

Cool Hysteresis Process

UDINT

Set the control switching
hysteresis for ON/OFF con-
trol. This determines how far
into the ON region the input
needs to move before the
output actually turns on.

0.000 to 999.999 units, if
Sensor Type is set to
mA or Volt.
(default = 1.000)

Proportional Term

UINT

View the active proportional
term for PID diagnostics.

0.000 to 1.000

(this value multiplied by
100 equals the percent
power)
