  • Entry
  • Associated product(s)


Problem
The following application shows you how to easily transfer large data volumes from a WinAC RTX controller to an other S7 controller and back via Industrial Ethernet.

Solution
In this application, S7 communication via Industrial Ethernet is used for transferring data volumes as large as possible.

Solution Requirements

This application comprises the following points:

  • On pages of the WinAC RTX controller, the Ethernet interface integrated in the PC is used as communication processor together with the SIMATIC NET SOFTNET-S7 software.

  • A (mutually configured) S7 connection is used.

  • A data package is transferred in any direction.

  • The data package has the size of 16Kbyte (maximum size of a DB in the CPU315-2 DP)

Functional structure

The following figure shows the interaction of the automation components, which are described in this example, in principle.

Hardware configuration

Here you see the hardware setup realized for this application, as well as the software to be installed for the components.
