Double command
Double commands (DC) are process outputs, which the on and off command can give separated on different
binary outputs.
Double-point indication
Double-point indications (DI) are process indications which visualize 4 process states at 2 inputs: 3 defined
states (for example, On/Off and disturbed position) and 1 undefined state (00).

specified environment. The environment is not influenced in any impermissible way here.

Fast-Scan Recorder
A fast-scan recorder records individual current and voltage sampled values with a sampling rate that is high
enough for the display of network events and transients. Recording starts once the value of an analog quantity
exceeds or drops below a specified limit. High-speed fault recording is used for acquiring brief transient events
of 1-2 seconds.
FG
See Function Group
Fleeting Indication
Fleeting indications are single-point indications present for a very short time, in which only the coming of the
process signal is logged and further processed time-correctly.
Floating
Floating means that a free potential not connected to ground is generated. Therefore, no current flows
through the body to ground in the event of touching.
