3.1 Local service
3.1.1 Introduction
In this example configuration, the service technician's programming device or PC is directly
connected to the SCALANCE M874-3 via Ethernet and the S7 automation system is connected
via the PROFINET interface. An S7-300 with CPU 317-2 PN/DP is used as the S7 automation
system.
In addition to the programming software (TIA Portal), the TIA Portal Cloud Connector is also
required on the PG/PC. SCALANCE M874-3 has an integrated TIA Portal Cloud Connector. The
two TIA Portal Cloud Connectors form the endpoints of the communication connection
(unsecured).
The TIA Portal Cloud Connector of the SCALANCE M874-3 is the server and the TIA Portal
Cloud Connector on the PG/PC is the client.
The pre-defined IPv4 rule "Cloud Connector" is enabled to prevent unauthorized access by
network devices to the "TIA Portal Cloud Connector" of the device. Only the service technician
is authorized to access the communication connection.
Via this communication link, the service technician accesses the connected S7 automation
system via the programming software and reads out the diagnostic buffer.
