5Ć6 Configuration Tips

Note:

The loadable function method does not require the

general register used with the register method, and

also uses two less FST instructions.

Example 2: Discrete Loadable Function

Given the above example, it is desired to close FV-1 when PMP-1 is

not running. Discrete input 1 will be set to a logic 1 when the pump is

stopped. Following are two possible ways to implement that strategy:

DI(1), {Read pump status}

RGST( PMP1STS ), {Store in register PMP1STS}

AINSQR(2, FT–1R ), {Load recirc flow in SVA}

RGSTA( FT–1RFLW ), {Store in register FI–1RFLW}

AINSQR(1, FT–1 ), {Load pump flow in SVA}

DIF( FT–1RFLW ), {Determine out flow}

TRK(ENABLED, ZERO, PMP1STS), {Close valve if pump stopped}

CNTRL,

STAT,

AOUT(1),

Loadable Function Method:

AINSQR( 1, FI–1R ), {Load pump flow in SVA}

DIF(AINSQR( 2, FI–1R )), {Subtract recirc flow to

determine out flow}

TRK(ENABLED, ZERO ,DI(1)), {Close valve if pump stopped}

CNTRL,

STAT,

AOUT(1),

Note:

The general register ZERO is a reference register with

0.00 stored as an initial value in the SVA.

As you can see, the use of loadable functions may greatly reduce

requirements for both general registers and FST instructions.
