case the UDR mapped indication point has no original Modbus point location, then the
event comes from its UDR point location.

Modbus user definable area set up for SPA ZC-302 polling

In this example phase currents IL1...IL3 are mapped into user definable register
addresses 0xB...0xC (11...13). Some indication bits that have been assembled into
register 0xD (14): LEDPTRC1.Str.general and LEDPTRC1.Op.general correspond
to the Start/Operarate LED states on the IED front. CB1 Open, Close and Fault are all
Circuit Breaker1 position data. Furthermore it is assumed that this data is mapped in
Profibus offset addresses 4 onwards.
