You can use the SIMATIC S7 Communication, for example, for data transfer via the integrated PROFINET interface and Industrial Ethernet interface of the S7-1500 CPUs and S7-1200 CPUs.
The following instructions are available for S7 Communication:
- PUT for sending data
- GET for receiving data
In STEP 7 (TIA Portal) you will find the above-mentioned instructions in the “Instructions” task card under “Communication > S7 Communication”.
The example describes how to configure an S7 connection between an S7-1500 CPU and an S7-1200 CPU to exchange data between the S7-1500 CPU and the S7-1200 CPU using the PUT and GET instructions.
Access from the remote partner via PUT/GET communication must be permitted in both S7 CPUs between which the S7 connection is configured.
