INSTRUCTION NAME: DI (discrete input)
DESCRIPTION : This instruction sets the SVD output equal to logic 1 when the value of the SVD
input, at the channel specified by operand 1, is between 0 and 1 volt dc across the discrete input
terminals. When the SVD input value is between 4 and 28 volts dc across the terminals, the SVD
logic output is 0. The SVA input remains unchanged.
