Interoperability
The document describes the interoperability of the IEC-104 IO
application used to control the device internal I/O board signals.
This document does not describe the interoperability of the IEC
60870-5-101 to IEC 60870-5-104 gateway application.
This companion standard presents sets of parameters and alternatives from which
subsets must 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 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 interoperability list is defined as in IEC 60870-5-101 and extended with
parameters used in this standard. The text descriptions of parameters which are not
applicable to this companion standard are strike-through (corresponding check box
is marked black).
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.
The selected parameters should be marked in the white boxes.
