Fieldbus Discrete Output data manipulation

When the DO[n] from the Device Control (DEVCTL) function block is wired to the
CAS_IN_D input for a fieldbus Discrete Output function block, the Control Builder
automatically creates a CEE output agent to handle the discrete output to the fieldbus
block. The block-like output agent maps the Control Builder DO[n] with status parameter
