NETWORK (max number = 1)
Parameters
With reference to the Figure 68 and Figure 69, at power-on:
1. The Net_out of the various nodes are in the 0 (FALSE) condition;
2. The STOP signal is sent via the Net_out line;
3. When the RESET command is pressed on one of the nodes all the nodes that are present are started when the
START signal is sent;
4. As the end result, the Net_out of all the connected nodes is in condition 1 (TRUE) if the various Net_in inputs
are in condition 1 (TRUE);
5. The RUN signal is sent via the network of the 4 nodes present.
With reference to the Figure 68 and Figure 69, when the emergency stop is pressed in one of the
four nodes:
1. The Net_out moves to condition 0 (FALSE);
2. The STOP signal is sent via the Net_out line;
3. The next node receives the stop code and deactivates the output;
4. The stop command generates the stop code for all Net_in and Net_out lines;
5. As the end result, the Net_out of all the connected nodes is in condition 0 (FALSE).
6. When the emergency stop is restored to the normal position, all the nodes can be restarted by sending the START signal
with a single reset. The latter condition does not occur when ENABLE RESET NETWORK is not enabled. In that case, the
local reset method must be used. The system will employ about 4s to restore all the outputs of the blocks that make up the
network.
