PVLD PVLD

INSTRUCTION NAME: PVLD (process variable load)

DESCRIPTION: This instruction sets the SVA output equal to the value of the process variable

(PV) of the loop specified by operand 1. The process variable is the SVA input being used by the

PCA. The process variable value is converted from percent of span being used by the PCA to

engineering units (E.U.'s) using the engineering units low value (EULV) and the engineering units

high value (EUHV) of the loop specified by operand 1. The SVD input remains unchanged.

OPERAND DESCRIPTIONS:

Loop tag - The tag of the loop that contains the process variable value. The process variable

value is recalled from the process variable operating data register for the specified loop.

Comment - A comment up to 255 characters long.

FUNCTION EQUATIONS:

SVA(out) = (PV value)[(EUHV-EULV)/100] + EULV

SVD(out) = SVD(in)

Where: EULV = Engineering units low value

EUHV = Engineering units high value
