3Ć18 Theory of Operation: Point Processing

Original Ć June 1990CE4.2:CL6211

3.3.2.1 Modes

Manual Mode (MAN): In MAN mode, the operation of the Primary

Control Algorithm (PCA) is suspended, and the operator is allowed to

adjust the IVP. If output tracking is enabled, and output tracking override

in manual mode is enabled, the IVP is dictated by the track signal value.

If the set point tracking in manual mode option is enabled, then the

operator entered SP is overridden by the track signal value. Note that the

set point has no effect on the IVP. The bias value can also be changed.

Automatic Mode (AUT): While in AUT mode, the set point and the bias

(if applicable) are entered by the operator. All of the functions associated

with the PCA are then executed, which determines the final IVP unless

output tracking is enabled.

Remote Set Point Mode (RSP): RSP mode is similar to AUT in that the

PCA functions, or output tracking if enabled, determine the final IVP. In

RSP mode, the set point is received through a configured analog value,

The bias value can still be entered by the operator.

Supervisory Mode (SUP): The SUP mode is similar to the RSP mode

except that in SUP mode, the set point is received from a host computer.

and is not operator adjustable. The bias value can still be entered by the

operator.

Direct Digital Control Mode (DDC): In DDC mode, the operation of the

PCA is suspended, and a host computer controls the IVP. The operator

can still enter the set point unless the set point tracking in DDC mode is

enabled, in which case the operator entered set point is overridden by

the track signal value.

3.3.2.2 Mode Transfers

When a point is involved in a mode transfer, it is common for some or all

of the operating data to change. The mode transfer logic for each direct

control point guarantees that mode changes are bumpless and

balanceless.

Any Mode to Manual: The present value of the IVP and set point are

maintained until the operator initiates a change, unless Set Point Tracks

PV in MAN mode is enabled.

Manual or DDC to Automatic: The present value of all operating data,

including the set point and IVP, is used to initialize the PCA at the

beginning of the transfer. If enabled, transfer bias ramping begins

ramping the IVP from the value at the time of transfer to the value

calculated by the PCA.
