Communications processor SIMATIC CP 1545-1

for modern TIA plants


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, for example: MindSphere.


The communications processor CP 1545-1 with CloudConnect functionality enables the easy and reliable transfer of all data from SIMATIC S7-1500 to MindSphere or other cloud solutions - e.g. Microsoft Azure or IBM Cloud - which support the standardized MQTT protocol. The CP protects the SIMATIC S7-1500 station from unauthorized access with the integrated SPI (Stateful Packet Inspection) firewall.

The CloudConnect function of the CP 1545-1 is easy to configure with a few input screens in TIA Portal. All necessary parameters are first specified for the different cloud platforms. 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. The CP thereby reduces the data volume by transferring the individual data points in different cycles or when the value lies outside a defined range.

The CP 1545-1 enables integration into an IPv6 infrastructure: Parallel to connection to cloud applications, it supports connection to additional automation devices, for example HMI, via Industrial Ethernet by means of the SIMATIC S7 protocol.


Example application

Cloud connection with SIMATIC CP 1545-1 as an integral part of modern TIA plants


  • Simple IIoT data transfer to cloud-based solutions

  • Event-driven communication reduces the network load and the data exchange costs

  • Very easy configuration within TIA Portal – with just a few mouse clicks into the cloud
