Data Exchange

With the fieldbus coupler/controller, data is exchanged via the EtherNet/IP.
In the EtherNet/IP network the master controller can be a PC or a PLC.
The head stations of the WAGO I/O-SYSTEM 750 are slaves.
The master requests communication. This request can be directed to certain
head station by addressing. The head stations receive the request and,
depending on the request type, send a reply to the master.
The FC EtherNet/IP G4 ECO XTR is essentially equipped with two interfaces for
data exchange:
• the interface to the fieldbus (Master)
• the interface to the I/O modules.
Data exchange takes place between the fieldbus master and the I/O modules.
EtherNet/IP, as the fieldbus, uses an object model for data access.

The fieldbus coupler process image contains the physical data for the bus
modules.
These have a value of 0 ... 255 and word 512 ... 1275.
