That means also, if the switch has adefined end position for example, open, then the appropriate enable signal (in thiscase EN_OPEN) is false. The enable signals EN_OPEN and EN_CLOSE can betrue at the same time only in the intermediate and bad position state and if they areenabled by the interlocking function. The position inputs come from the logicalnodes Circuit breaker/Circuit switch (SXCBR/SXSWI) and the enable signalscome from the interlocking logic. The outputs are connected to the logical nodeSwitch controller (SCSWI). One instance per switching device is needed.1MRK 511 424-UEN B Section 8ControlBay control REC650 2.2 IEC 153Technical manual
