12.3.2.4 Logic diagram
The function contains logic to enable the open and close commands respectively if the
interlocking conditions are fulfilled. That means also, if the switch being controlled has its
position defined as open (via POSOPEN) for example, then the appropriate enable signal
output (in this case EN_OPEN) is false. The switch operation enable signals EN_OPEN
and EN_CLOSE can be true at the same time only in the intermediate and bad position
state of the switch (defined via POSOPEN and POSCLOSE) and if they are enabled by the
interlocking function. The position inputs come from the logical nodes Circuit breaker/
Circuit switch (SXCBR/SXSWI) and the enable signals , OPEN_EN and CLOSE_EN
come from the interlocking logic. The outputs are connected to the logical node Switch
controller (SCSWI). One instance per switching device is needed.
