9.5.1.1. Network (NETWORK) (max. number = 1)
Using the NETWORK operator, STOP and RESET commands are dis-
tributed via a local network. Using Network_IN and Network_OUT
it is possible to exchange START, STOP and RUN signals between
the various nodes.
Principle of operation
Using this operator you can straightforwardly distribute STOP and
RESET commands via a local MSC network.
Figure 187: Network
The following conditions must be met for the "Network" operator:
1. The input connected to a single or double Network_In input must be connected to the
Network_OUT output on the
previous module in the network.
2. The Network_OUT output connected to a STATUS output or an OSSD output must be connected to the Network_IN
input on the following module 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) or reset devices
(e.g. SWITCH).
4. The IN input can be connected as required to the logic (e.g. input function blocks or results of logical combinations).
5. The Output output can be connected in the logic as required. The output is "1" (TRUE) if the IN input is "1" (TRUE) and
the function block has been restarted.
Parameter
Enable Network Reset: If selected, the function block can be reset via the network. If not selected, the function block can
only be reset via the local Reset_IN input.
Enable Error Out: If selected, the STATUS output Error_OUT is available.
