• Overriding of interlocking functions
• Operation counter
The apparatus control is realized by means of a number of function blocks designated:
• LocalRemote switch (LOCREM)
• Bay control (QCCBAY)
• Switch controller (GNRLCSWI)
• Circuit breaker (DAXCBR)
• Circuit switch (DAXSWI)
The three latter functions are logical nodes according to IEC 61850. The signal flow
between these function blocks is shown in
these functions can be found in technical manual. Logical node for interlocking
(SCILO) in Figure 45 is the logical node for interlocking. Control operation can be
performed from the LHMI.
