Condition 3:
If the IN input on the NETWORK function block on one of the four nodes switches to the state "0"
(FALSE) (see Figure 49):
1. The local OUTPUT changes to the state "0" (FALSE).
2. The RUN signal continues to be sent via the Network_Out cable.
3. The states of the other nodes remain unchanged.
4. In this event the local reset method must be used. The "Reset_In" LED flashes to indicate this state. The relat-
ed node can be restarted using its reset.
The Reset_In and Network_In inputs and the Network_Out output can only be represented on the
I/O terminals of the base unit.
