The manipulated variable setpoint is limited in the positive direction to the value
set in MD 5474 before the D/A conversion. A message is sent to the PLC if the
limit is violated.

The manipulated variable setpoint is limited in the negative direction to the value
set in MD 5475 before the D/A conversion. A message is sent to the PLC if the
limit is violated.

The voltage output (manipulated variable) can be inverted in machine data MD
5476 in order to compensate for differences in sign in the piping or wiring. Alter-
natively, the wiring of the manipulated variable for the valve could be altered.
Definition of direction: See Subsection 3.9.1.
