6.3. Programmable control switch
The programmable control switch is a control function that controls its binary output signal. This output
signal can be controlled locally from the relay's mimic (displayed as a box in the mimic) or remotely from
the RTU. The main purpose of programmable control switches is to block or enable function and to change
function properties by changing the setting group. However, this binary signal can also be used for any
number of other purposes, just like all other binary signals. Once a programmable control switch has been
activated or disabled, it remains in that state until given a new command to switch to the opposite state
(see the image below). The switch cannot be controlled by an auxiliary input, such as digital inputs or logic
signals; it can only be controlled locally (mimic) or remotely (RTU).
