Figure 5-174 Emergency stop example for a network with four base modules
Restart after local stop
command
The points below relate to the two circuit diagram application examples (Figures 5-168 and
5-171):
1. After triggering a local safety demand at a base module via the “I
N” input of the “NET-
WORK” function block, the local “O
UT” output is set to logic “0”.
2. The network signal is still active (RUN).
3. The other local outputs of the base modules located in the network are not affected by
this.
4. In this case, the local safety function can only be activated via a reset. This condition is
indicated via the flashing LED of the “R
ESET_IN” input. The relevant base module can
only activate its local safety function via the local “Reset_in” input.
The “N
ETWORK_IN” input and the “NETWORK_OUT” output can only be mapped to the I/O ter-
minal points of the base module.
