Status information representing either the status of the process or of the function allocated to the LN, e. g. , switch type, switch operating capability, . . . Settings information needed for the function of a logical node, e. g. , first, second, and third reclose time, close pulse time, and reclaim time of an autoreclosing function. Measured values are analogue data measured from the process or calculated in the functions like currents, voltages, power, etc. , e. g. , total active power, total reactive power, frequency, net real energy since last reset, . . . Controls are data, which are changed by commands like switchgear state (ON/OFF), tap changer position or resetable counters, e. g. , position, block opening, . . . © SCC, Nov 2002; Madrid, Karlheinz Schwarz Page 38

SCC IEC 61850 Part 10: Conformance Testing Scope This part of IEC 61850 specifies methods for conformance testing of devices of substation automation systems. In addition it gives guidelines for setting up test environments and specifies levels of interoperability. Thus it enables the investigation of conformance claims and to establish their validity. © SCC, Nov 2002; Madrid, Karlheinz Schwarz Page 81
