Cascade control
(Block function)

To control one process, 2 inputs [CH2 as a master (1st-order controller), and CH1 as a slave (2nd-order controller)] are used for more advanced control.
MV is calculated from PV and SV of the master (CH2), and is used as SV of the slave (CH1), with which CH1 control computation is carried out, then outputs from CH1 control output.
[CH2 control output will be OFF (0mA for DC current output) or OUT2 (Cooling output) for Heating/Cooling control.]
MV (0 to 100%) of the master (CH2) corresponds to the SV (External setting low limit to External setting high limit) of the slave (CH1).

Heating/Cooling control output (Block function) This is 1ch Heating/Cooling control output spec. CH1 will be Heating output (OUT1) and CH2 will be Cooling output (OUT2), followed by control performance.
OUT2 proportional band (P) 0.0 to 10.0 times OUT1 proportional band
(ON/OFF control when set to 0.0.)
Integral time (I) Same as that of OUT1
Derivative time (D) Same as that of OUT1
OUT2 proportional cycle 1 to 120sec
ARW Same as that of OUT1
Overlap/Dead band Thermocouple, RTD input: -100.0 to 100.0 ()

OUT2 high limit,

0 to 100%
(DC current output: -5 to 105%)

DC current 4 to 20mA DC, Load resistance: Max 600
External setting input
(Block function)
External analog signal will become the SV.
Control desired value (SV) adds remote bias value to the External setting input value.
As a setting signal, specify any DC range during input type selection via console software.

DC voltage: 1 to 5V or 0 to 1V DC
Allowable input DC current: 50mA DC or less

To use Transmission output, specify 'Current' for CH2 control output.
Resolution 1/10000
Current 4 to 20mA DC (load resistance Max 550)
Output accuracy Within 0.3% of Transmission output span
CH1 PV difference (CH1-CH2) input

PV = (CH1 PV - CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel.
CH1 PV addition (CH1+CH2) input
(Block function)
Addition value of CH1 and CH2 will be the input value for CH1, and control is performed using this value.
PV = (CH1 PV + CH2 PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and addition depend on the reference channel.
CH2 PV difference (CH2-CH1) input
(Block function)

Temperature difference between CH1 and CH2 (CH2-CH1) will be the input value for CH2, and control for CH2 is performed using this value.
PV = (CH2PV - CH1PV)
Set values such as input type, scaling and PV filter time constant can be individually set to CH1 and CH2.
However, if CH ranges differ from each other, indication and difference depend on the reference channel.

CH2 PV addition (CH1+CH2) input
(Block function)
Addition value of CH1 and CH2 will be the input value for CH2, and control is performed using this value.
