Network example
This example shows a TIA Portal network configuration and the API interfaces that represent
the networked devices.
Assume that all the devices in the top row (PLC_1, IO device_1, and PLC_2) are connected
to an external Ethernet network (not shown), and so can be directly accessed by the
SIMATIC Automation Tool API. Further, assume that the PROFINET subnet connected to
PLC_2 is not connected to the external network.
The SIMATIC Automation Tool API can provide information and operations for all the PLCs
and I/O stations in this configuration.
