Siemens CP 1545-1 Communications processor

The SIMATIC CP 1545-1 communications processor securely connects the SIMATIC S7-1500 controller to Industrial Ethernet networks. The new CloudConnect functionality enables easy and reliable transfer of all selected data from the SIMATIC S7-1500 to MindSphere, or a cloud solution that supports the standardized MQTT protocol, e.g. Microsoft Azure or IBM Cloud. The CP protects the SIMATIC S7-1500 station from unauthorized access with the integrated SPI (Stateful Packet Inspection) firewall. Data from cloud systems or MQTT brokers can also be received using the MQTT protocol. The CloudConnect function of the CP 1545-1 is easy to configure with a few input screens in TIA Portal. First, all the parameters required for the different cloud platforms are specified. The data intended for the cloud is then selected from the tag management of the SIMATIC S7-1500 and saved as topics to be transferred with the corresponding trigger conditions. All functions are configured using STEP 7 Professional V15.1 update 3 (TIA Portal) or higher. The CP 1545-1 is used to connect the SIMATIC S7-1500 to Industrial Ethernet networks. With its own processor, it relieves the CPU of communications tasks and facilitates additional connections. As a modern IoT component for the S7-1500 system, the CP 1545-1 transfers data to cloud systems or MQTT brokers using the MQTT protocol. It is also possible to receive data, thus making it easy to network systems connected to an industrial backbone.
