5.1.1.7. General functions
5.1.1.8. Standard functions
Standard functions are used for logics, such as interlocking, alarming and control
sequencing. The use of logic functions is not limited and the functions can be
interconnected with each other as well as with protection, measurement, power
quality, control, condition monitoring and general functions. In addition, the digital
inputs and outputs as well as LON inputs and outputs can be connected to standard
functions by using the Relay Configuration Tool.
