9 Interoperability

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 informationobject 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 incommand and in monitor direction allow the specification of the complete set orsubsets, as appropriate for given applications. This clause summarizes theparameters of the previous clauses to facilitate a suitable selection for aspecific 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).

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.

The selected parameters should bemarked in the white boxes as follows:

[ ] Function or ASDU is not used
[ X ] Function or ASDU is used as standardized (default)
[ R ] Function or ASDU is used in reverse mode
[ B ] Function or ASDU is used in standard and reverse mode

The possible selection (blank, X , R , or B ) is specified for each specific clause or parameter.

A black check box indicates that the option cannot be selected in this companion standard.
