Instead of every single sensor having to be connected to the cloud, the Simatic S7-1500 enables field data aggregation and subsequent linking to additional process-relevant information if required. The CP 1545-1 then transfers the data to the cloud platform. The communications processor also features an integrated Stateful Packet Inspection (SPI) firewall for protecting the S7-1500 against unauthorized access. The CloudConnect functionality is easy to project in the TIA Portal using just a few input screens.
There are two ways to connect existing systems with the Industrial IoT Gateway CloudConnect 7: Simatic CC712 facilitates connection of one Simatic S7-300 or S7-400 via Industrial Ethernet by means of the S7 protocol. With Simatic CC716, on the other hand, up to seven Simatic S7 controllers can be connected via Industrial Ethernet or Profibus/MPI interfaces.
The existing automation program does not have to be changed in order to select and transfer the essential information. In addition, the data read by CloudConnect 7 from lower-level S7 stations can be made available as OPC UA variables (server). This enables standardized data exchange, for example with MES systems or HMI and third-party controllers.
The open Message Queuing Telemetry Transport (MQTT) cloud protocol is used in all cases. This established standard also makes it possible to transfer data to MindSphere, the IoT operating system from Siemens, as well as to other cloud platforms.
