It is possible to realize a connection from a WinCC flexible Runtime/Panel to a S7-200 PPI station over ethernet using an Echolink S7 Compact gateway.

Example

In the following example a configuration with WinCC flexible is shown. The HMI station ist connected to the Echolink S7 Compact via an Ethernet connection. The Echolink S7 Compact itself is connected to a S7-300/S7-400 station by MPI or PROFIBUS. Bus parameters were configured by the IBHNet configuration tool.

The following addresses were chosen in the example:

IP addresses:

StationAddress
HMI station192.168.0.194
Echolink S7 Compact192.168.0.167

MPI/DP addresses:

StationAddress
Echolink S7 Compact5
S7-300/400 station12

 

Configuration: The ethernet communication driver for S7 300/400 must be selected in WinCC flexible, since only this driver allows the selection of an extension slot on the PLC side. This setting is necessary for the selection of the MPI/DP address to use for the connection.

The echolink s7-compact terminates automatically. No termination resistor needs to be set. The gateway can therefore be connected independently of this at the beginning or end of a Profibus network. Due to the piggyback assembly, it can easily be plugged onto the existing Profibus cable.
