Network (Max Number = 1) - Reer MOSAIC M1 Installation And Use Manual

MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC

NETWORK (max number = 1)

The Network operator is used to distribute Stop
and Reset commands via a simple local network.
Use Network_in and Network_out to exchange
START, STOP and RUN signals between the
different nodes.
Operating principles.
This operator allows stop and reset commands to
be simply distributed in a local Mosaic network.
The Network operator requires the following:
1) the Network_In input (single or double) must be connected to the Network_Out output of
the preceding unit in the local network.
2) the Network_Out (could be a STATUS or OSSD output), must be connected to the
Network_in input of the next unit in the local network.
3) the Stop_In and Reset_In inputs must be connected to input devices that act as Stop (e.g.
E-STOP) and Reset (e.g. SWITCH), respectively.
4) the In input can be connected freely in the diagram (e.g. input function blocks or results of
logical combinations).
5) Output can be connected freely in the diagram. Output is 1 (TRUE) when the IN input is 1
(TRUE) and the function block has been restarted.
Parameters
Enable Reset Network: when selected allows the distribution network to reset the function block.
If not enabled, the function block can only be reset via the local Reset_In input.
Enable error out: if selected, it enables the Error_Out output that can be used to signal, with a logic
1 (TRUE), the presence of a failure.
Global Reset Enable: if selected, the operator can restart the entire system with the reset button
from any node in the network. If deselected the operator can restart all the nodes that have been
not caused the stop from anywhere in the network, except the node that has caused the stop (this
node has to be restarted with its own reset).
Stop cause: (only M1S) if selected, it enables the Network_stop and Local_stop outputs and
indicates the cause of the STOP status. These outputs are normally at 0 with the system in RUN and
the Output at 1 (TRUE). If a network stop is requested, the Network_stop output increases to 1(TRUE).
If the Output output goes to 0 due to the In input or the Stop_in input, the Local_stop output goes
to 1 (TRUE). The outputs will remain in this status until the next main reset.

The RESET command must be installed outside the zone of operation in a position where the
zone of operation and the entire work area concerned are clearly visible.

The maximum number of MASTER modules that can be connected in network
configuration is equal to 10.

Each Master module can have a maximum of 9 expansion modules connected.
Condition 1:
With reference to the Figure 86 and Figure 87, 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.
