3. IEC 60870-5-104 PROFILE - 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 choice of “structured” or “unstructured” fields of the INFORMATION OBJECT
ADDRESS of ASDU 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 summarises 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.
Paragraph in grey are those which are not applicable for the IEC 60870-5-104 profile.
The selected parameters should be filled up (
N => S
).
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.
To simplify the PID , we use the following conventions:
N Not supported
S Supported
C This is configurable
R
Could be received, but not managed.
