Description

Although, according to the number of installed nodes PROFINET is the largest
Ethernet based fieldbus in the world, EtherNet/IP is at number 3. Especially in
several regions of the world EtherNet/IP has a dominating role. SIMATIC controller
inherently don't have support for field devices using EtherNet/IP.
In this application example a possible solution is demonstrated and explained, how
such EtherNet/IP field devices can still be used with SIMATIC controller. Here
SIMATIC controller applies to both S7-1500 and S7-1200.
In this example the S7-1200 will be operated as such EtherNet/IP field device
together with the ET200SP MF interface module. The S7-1500 shown in the below
schematic is operated as the device controlling the field devices.
NOTE The roles of the S7-1200 and S7-1500 can be exchanged without changes in the
description as the LCCF_EnetScanner function block exists for both systems.

As mentioned above the ET200SP MF and the S7-1200 controller are operated as
field devices providing sensor signals to the S7-1500 controller and accepting
control signals from the S7-1500.
The real setup also contains a SCALANCE X208 switch for easier connectivity.
However, the switch is not necessary as a line topology (as shown above) is also
possible.
