Echolink S7 Compact:S7-300/S7-400 WinCC flexible

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:

Station Address
HMI station 192.168.0.194
Echolink S7 Compact 192.168.0.167

 

MPI/DP addresses:
Station Address
Echolink S7 Compact 5
S7-300/400 station 12

 

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.

Besitzt das s7-compact einen Bus-Widerstand?

Das echolink s7-compact terminiert automatisch. Es muss kein Widerstand speziell gesetzt werden. Das Gateway kann also unabhängig dessen am Anfang oder Ende eines Profibus-Netzwerkes angeschlossen werden. Durch die Huckepack-Montage kann es einfach auf das vorhandene Profibus-Kabel aufgesteckt werden.
