7.9 Interoperability
This companion standard presents sets of parameters and alternatives from
which subsets have to be selected to implement particular telecontrol systems.
Certain parameter values, such as the number of octets in the COMMON
ADDRESS of ASDUs represent mutually exclusive alternatives. This means that
only one value of the defined parameters is admitted per system. Other
parameters, such as the listed set of different process information in command
and in monitor direction allow the specification of the complete set or subsets, as
appropriate for given applications. This clause summarizes the parameters of the
previous clauses to facilitate a suitable selection for a specific application. If a
system is composed of equipment stemming from different manufacturers it is
necessary that all partners agree on the selected parameters.
The selected parameters should be crossed in the white boxes (replace " " with
"⌧").
NOTE In addition, the full specification of a system may require individual selection of certain
parameters for certain parts of the system, such as the individual selection of scaling factors for
individually addressable measured values.
