3.2 Remote service
3.2.1 Introduction
In this example configuration, the service technician accesses a server in the service center
via remote desktop. In addition to the programming software (TIA Portal), the TIA Portal
Cloud Connector is also installed on this server.
SINEMA RC is used to secure the TIA Portal Cloud Connector communication connection.
SINEMA RC provides secure management of tunnel connections (VPN) between the service
technician and the service technician as well as the SCALANCE M874-3 and the service
center. The Service Center is connected with the SINEMA RC server via LAN and can be
reached in this way.
To manage the tunnel connection, the SCALANCE M874-3 device and a user for the service
technician are created on the SINEMA RC server.
The service technician and the SCALANCE M874-3 device establish a connection to SINEMA
RC separately. This is the SCALANCE M874-3 via the "SINEMA RC" function and the service
technician via the SINEMA RC client.
The communication connection of the two TIA Portal Cloud Connectors (client and server)
goes through the VPN tunnel connection and is secured in this way.
Through this secure communication connection, the service technician accesses the
connected S7 automation system via the programming software and reads out the diagnostic
buffer.
