NETWORK
Using the NETWORK operator, STOP and
RESET commands are distributed via a lo-
cal network. Using Network_In and Net-
work_Out it is possible to exchange
START, STOP and RUN signals between the
various nodes.
Principle of operation
Using this operator you can straightfor-
wardly distribute STOP and RESET com-
mands via a local MSC 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 con-
nected to the Network_In input on the following module in the 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) Output can be connected in the logic as required. Output is "1" (TRUE) if the IN input is "1"
(TRUE) and the function block has been restarted.
Parameters
Enable Reset Network: 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.
Application example:
Network data flow
The RESET command switches must be installed outside the danger areas for the
network in places at which there is a clear view of the entire work areas affected.
