Ethernet Communication (ISO on TCP) between SIMATIC S5 and SIMATIC S7-1500 Controllers
One of the standard communication structures for systems is the star topology. A head-end station (PC or SIMATIC head-end station) communicates with several substations. These substations, however, also communicate with each other via cross-communication. In SIMATIC S5 systems, the communication of a control center/ SIMATIC S5 head-end station to its substations is often implemented by means of the FETCH/WRITE service. Cross-communication between SIMATIC S5 substations is done via the SEND/RECEIVE service.
The example projects/scenarios in this document show the options available to establish a communication via Industrial Ethernet (ISO on TCP) between the existing SIMATIC S5 controllers and the SIMATIC S7-1500 via the available protocols and services. The figure below shows the underlying hardware setup and the communication variants of this example.
You will be provided with master copies which can be quickly used and extended in your own migration projects. Detailed knowledge on the SIMATIC S5 is not required.
