Creating The Ethernet/Ip Io System - Siemens S7-1200 Manual

4 Configuration/Engineering
Step
6. Assign the interface you want to use to
the actual parameter of the block call
NOTE It is recommended to use the TIA Portal maintained global constants for the
interface identifier. Otherwise the function block may not work properly.
However, any Open User Communication (OUC) capable interface may be used,
including Industrial Ethernet CM or CP extension cards.
At this point the LCCF_EnetScanner function block is not operable. The
configuration of the EtherNet/IP field devices needs to be done and an area to for
the sensor and control data needs to be declared.

Creating the EtherNet/IP IO system

Similar to PROFINET or PROFIBUS there is a managing device in an EtherNet/IP
network. In this application example it is realized by the S7-1500. The managing
system is called the Scanner.
For the Scanner to know, which managed devices, called Adapters, are in the
scope, it requires some information. These information are describing the
parameters of the data exchange. They contain as minimum:
•
Addressing information of the Adapter
•
Update rates for both Inputs and Outputs
•
Amount of data to be exchanged
As for EtherNet/IP there is no graphical way to configure the EtherNet/IP IO system
in TIA Portal the LCCF_EnetScanner function block accepts the configuration in
the form of an array of Adapter descriptions. The descriptions are best stored in a
global DB. In this application example the DB is called "EnetIoSystem", which
stores the array with the adapter descriptions in it.
