Control Alg

PIDA (default)

 

PID A - is normally used for 3-mode control.

 

 

PIDB

 

The output can be adjusted somewhere

 

 

Duplex A

 

between 100 % and 0 %. It applies all three

 

 

Duplex B

 

control actions -Proportional (P), Integral (I),

 

 

 

 

and Derivative (D) - to the error signal.

 

 

Note:

 

PID B - Unlike the PID-A equation, the

 

 

In PID A, a step

 

analyzer gives only an integral response to a

 

 

change in setpoint

 

setpoint change, with no effect on the output

 

 

will result in a step

 

due to the Gain or Rate action, and gives full

 

 

change in output.

 

response to PV changes.

 

 

In PID B, step

 

DUPA - like PID A but provides an automatic

 

 

changes in setpoint

 

 

 

 

method to switch tuning constant sets.

 

 

will not bump the

 

 

 

 

 

 

 

 

output; the output

 

DUPB - like PID B but provides an automatic

 

 

will slew smoothly

 

method to switch tuning constant sets.

 

 

to the new value.

 

Note: For Duplex A and Duplex B if the output

 

 

 

 

 

 

 

 

is greater than 50%, then tuning set 1 is used.

 

 

 

 

If the output is less than 50%, then tuning set 2

 

 

 

 

is used.

 

 

 

 

 

Control Action

Direct

DIRECT - PID action causes output to

 

 

Reverse (default)

increase as process variable increases.

 

 

 

REVERSE - PID action causes output to

 

 

 

decrease as process variable increases.

 

 

 

 

 

 

Power Mode

Manual(default)

 

Mode permitted at power up.

 

 

Last

 

 

 

 

 

 

 

 

 

Power Out

Failsafe (default)

 

Output at Power up

 

 

Last

 

FAILSAFE - Failsafe output value.

 

 

 

 

 

 

 

 

LAST - Same as at power down.

 

 

 

 

 

 

Failsafe Out

-5.00 to 105.00%

 

Failsafe Output Value – The Output value to

 

 

default = 0.00

 

which the analyzer will go if there is a power

 

 

 

 

down or Failsafe condition (Input Faults).

SP Power On

Last

 

Setpoint at Power up

 

 

 

LAST - Same as at power down.

 

 

Local SP(default)

 

Local SP – Local Setpoint value.

 

 

 

 

 

 

RSP Source

Any Analog Signal

 

Selects the analog signal that will be used as

 

 

See Table 6-3

 

the remote setpoint. The remote setpoint

 

 

 

 

should be supplied in PV engineering units.

 

 

 

 

 

 

Ratio

1.0 (Default)

 

Ratio that is applied to the Remote Setpoint.

 

 

-20 to 20
