Object Dictionary (SDO)

Service Data Object (SDO) is used to transfer data that does not require continuous updates or is not critical to the

ongoing process. Any NRG parameter can be set via an SDO even if this is included in the start-up parameters.

Reading and writing is possible for all variables except for variables related the SSR history as indicated in the tables

below. The datatype of each index is uint16. The indexes are in a big endian format.

SDO - RG..Ns

The below parameters are available for all RG..Ns on the bus chain. The
