6.2 Notes for parametrization in DIGSI
Only those SIPROTEC objects can be transmitted or controlled by
Modbus which are listed in the column “Designation of the SIPROTEC
objects“.
All these objects are already contained in the standard parameter set
and they can be identified by their name or their "Internal object no." (not
all SIPROTEC objects have an internal object number).
For transmission of installation-specific commands and annunciations
user-definable objects are available.
Binary outputs and binary inputs of the SIPROTEC device can be
assigned to these objects using the DIGSI parameterization software
(ref. to chap. 6.3.2 and 6.4.1).
CFC-Incoming annunciations and CFC-Output indications can be used
to allocate protection annunciations, which are not containd in the
standard mapping to positions in Modbus registers (ref. to chap. 6.3.4
and 6.4.2).
