    ■ Logical AND Connection Signals Pulse signals are used in the G9SX logical AND connection and dynamic processing is used to monitor the signals. Information on safety between Units is passed by these pulse signals, which are also used to detect faults in the connection and short circuits.
  • Page 92 2. Logical AND Connections ■ Simplifying Safety Circuits Safety circuits were traditionally built by combining relay contacts, but now the logical AND connections of the G9SX simplify building safety circuits.
