Task:
With the networking of different systems increasing, the necessity of
SIMATIC products being able to communicate with devices of external
providers also increases. Here, Allen-Bradley or Rockwell products which
especially penetrate the US market are of special interest.
The present configuration presents the "Echochange" gateway made by
INAT GmbH by means of which both networks can communicate with each
other via Ethernet interfaces.
Solution:
The "Echochange" gateway is equipped with two Ethernet interfaces which
can be parameterized differently. Thus, it is possible to link the
Ethernet/IP communication on the Allen-Bradley side to the Industrial
Ethernet/ISO-on-TCP communication on the SIMATIC side. By means of the
"AG_SEND"/"AG_RECV" blocks, a S7-300 CPU then can exchange data with the
ControlLogix CPU on the Allen-Bradley side.
The "Echochange" gateway allows easy connection of two existing
Ethernet networks with low hardware and configuration effort. In
principle, it is also possible to connect other controls and other
Ethernet variants as the ones presented here. The usefulness is limited
by the restriction to "integer" as the only data type which the
concerned controls are allowed to exchange.
The document presents the functionality of the gateway including
its major configuration steps and essential background information.
Nevertheless, the document only is intended for orientation; it does not
contain a complete and runnable configuration.
