Protocol IEC (master) SPIDER

Transcription

1 Protocol IEC (master) SPIDER Indications Both sinle and double indications are supported with or without time ta. Analo Measured Values Supported, but only without time ta. Diital Measured Values Supported, but only without time ta. Pulse Counter Values The pulse counters are frozen locally in the controlled stations at specified point of times. The frozen counter values are reported spontaneously. The included time ta is the point of time for the freezin. The used method is described as method 1 (Acquisition of interated totals) in IEC , chapter 6.9. Commands Both sinle and double object commands are supported. Reulatin step command is supported. Set point command is supported. Bit strin command is supported. Clock Synchronization The clock synchronization is initially performed accordin the procedure defined in IEC However, if the controllin station does not reply on 'delay acquisition command' ASDU 106, the controllin station will adapt to that. Then the clock synchronization is performed accordin to the Norweian IEC User Convention. Network Confiuration Point-to-point and multidrop confiurations are supported. Redundant lines are not included in the IEC protocol standard. However, redundant lines can be used if the implementation in the RTU is accordin to the Norweian IEC User Convention. Loop confiuration is not supported. Sub-RTUs are not supported. Dial-up is not supported.

2 2 Technical data Scope of Implementation Supported Not supported Some restriction, see comment Always used, i.e., must be supported by the controlled station Network confiuration Point-to-point Multiple point-to-point Multipoint-party line Redundant lines Note that redundant lines are not included in the IEC protocol standard. The box for Redundant lines is white if implementation in the RTU is accordin to the Norweian IEC User Convention, version 2.0.
