2.1 Local service
2.1.1 Introduction
In this example configuration, the PG/PC of the service technician is directly connected to the
SCALANCE M804PB via Ethernet and the S7 automation system via the MPI/DP 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 or STEP 7), the TIA Portal Cloud
Connector is also required on the PG/PC. SCALANCE M804PB 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 M804PB 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.
