Examples of applications
3.10 Connecting a PROFIBUS network to a PROFINET installation
Industrial Ethernet
122 System Manual, 09/2019, C79000-G8976-C242-10
Solution
The new solution consists of Industrial Wireless LAN and PROFINET IO. This combines a
high data rate in the wireless communication with a communications concept for modular
distributed applications based on Ethernet.
The SIMATIC S7-1200 ⑥ used on the shuttle conveyor has an integrated PROFINET
interface. A SCALANCE W748-1
⑦ client module is connected to this interface for wireless
communication. In the stationary part of the system, an IE/PB LINK PN IO
⑧ in conjunction
with a SCALANCE W722-1 allows unchanged usage of the ET 200M modules. A
SCALANCE W788-1
⑨ is used as the access point through whose Ethernet interface the
operator control stations
⑩ can access the entire system.
Benefits
● High data throughput and high reliability in communication with the shuttle conveyor
without trailing cables or sliding contacts.
● Transparent network with wireless PROFINET/PROFIBUS gateway
● When necessary, a PC with a WLAN interface can be used for diagnostics and for
process visualization.
● Lower operating costs and reduction of downtimes with maintenance-free IWLAN
technology, resulting in higher productivity.
● Investment protection due to use of an IE/PB LINK PN IO. The existing ET 200 M
controllers can continue to be used unchanged.
