Analog Output Functional Block

The Analog Output Functional Block

The Analog Output functional block translates an input network variable value
to a value that is used to drive a hardware output. The functional block may be
configured to translate the value into voltage or current, depending on the
requirements of the hardware output being driven. The following figure and
tables summarize the inputs and outputs of the Analog Output functional block:
