Meaning of data
Service Data Objects SDO
Service Data Objects are used for read/write access to the
entries of the object dictionary.
You can use an SDO to read out or alter all the data of the
circuit-breaker or the DMI.
Data access
The manufacturer-specific object “Command” (index
2021
hex
, subindex 00
hex
) is used for access to the NZM or
DMI data, with an additional command code.
This command code defines whether read or write access is
to be performed, to which DMI address it applies
(
a chapter “Data”, from page 23) and how many bytes it
contains.
Actuate circuit-
breaker The circuit-breaker is switched on or off via a motor operator;
Requirement: the “Motor mode” bit is set to 0
00 Do not change status
01 Switch off (Output 4 = 1, Output 5 = 0)
10 Switch on (Output 4 = 0, Output 5 = 1)
11 Do not change status
Remote operator
mode Changes the use of the outputs 4 and 5
0 Use Outputs 4 and 5 for remote operator (see above)
1 Outputs 4 and 5 are set directly by the
corresponding bits
Outputs 0 to 5 Digital outputs of the DMI
Inputs 0 to 5 Status of the digital inputs on the DMI
Reserved Not evaluated
