Designing and Planning a Network

With PROFINET IO it is also possible to include wireless parts using WLAN into the network. The only restriction is that the wireless component must support VLAN.

The reaction time will increase if using WLAN, because WLAN has less data throughput then wired networking.

Caution

:strong:Risk of communication faults!

ETHERNET components without VLAN-tag-support will not work properly in PROFINET IO networks. Make sure that all ETHERNET-devices support the VLAN-tag.

Note

Because of PROFINET IO requirements on data throughput, switches with support of 100 MBit/s and full duplex are mandatory.

• Topologies
  • Star
  • Tree
  • Bus (also called line)
• Parallel operation of different PROFINET IO systems in one network
