CERTUS Installation Manual
Condition 1:
With reference to the figure, at power-on:
1. The OUTPUTs of the various nodes are in the 0 (FALSE) condition;
2. The STOP signal is sent via the Network_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 OUTPUT of all the connected nodes is in condition 1 (TRUE) if
the various IN inputs are in condition 1 (TRUE);
5. The RUN signal is sent via the network of the 4 nodes present.
Condition 2:
With reference to the figure, when the emergency stop is pressed in one of the four nodes:
1. The OUTPUT moves to condition 0 (FALSE);
2. The STOP signal is sent via the Network_out line;
3. The next node receives the stop code and deactivates the output;
4.
The stop command generates the stop code for all Network_in and Network_out lines;
5. As the end result, the OUTPUT 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.
Response Time
The response time of the network starting from emergency stop is given by the formula:
trTot = (120ms x n°module) (max 10)
