Configuring the UDC Module, Regulator Type, and Parameters

The Minimum Value must not be less than -32768. The Maximum Value must not be
greater than 32767. The Minimum Value must be less than the Maximum Value.
Note that the PMI meter ports have 8-bit resolution and are updated on the average of
every 1.0 milliseconds.
See the PMI Regulator instruction manual (S-3057) for more information about the
PMI meter ports. See section
3.7.2.1 of this instruction manual for information about
resolution of data.
PMI meter ports can also be set up on-line using the “Setup UDC” selection from the
Monitor menu as described in the AutoMax Programming Executive instruction
manual. If the meter ports are set up during parameter entry, the information is loaded
onto the UDC module in the AutoMax rack along with all other parameter data. The
meter port setup can then be changed on-line under “Setup UDC,” but this method
would not actually write over the PMI meter port setup that was loaded to the rack.
Instead, the new setup would be valid only until there was a Stop All or a power cycle,
in which case the original setup would be used to determine what data to send out of
the meter ports.
