I-7550E PROFIBUS/Ethernet Converter User Manual

(Version 1.00, June/2014)

PAGE: 35

4. Communication

4.1 Field of application

A master station can be a PLC, PC or any other smart device. The system can be a
mono-master system (

Figure 23

) or a multi-master system (

Figure 24

). The I-

7550E enables the integration of the Ethernet devices into a PROFIBUS DP
network.
