Software switch controller function (SOFTSW)
Sixty-four position software-switches (CBK, ICB, SCB, and -01 to -61) are provided in the IED
memory as virtual switches; they are used to determine the operation of internal processes in
the IED. Either the criteria “Enable (On)” or “Disable (Off)” may be applied for each software
switch, S43. Three software switches have already been defined for special purposes; the three
are controlled by command blocking (CBK), interlock bypassing (ICB), and synchronism
bypass (SCB) functions. On the other hand, switches S43-01 to S43-61 are provided for general-
purpose usage.

Note: The implementation of such features depends on the selection of hardware and the
configuration of functions. Several IED models do not have its features. To determine whether
its features are implemented in the IED, locate the IED ordering number; and check the order
number at the “G&T position” referring to the comparison table below. For more information,
