Topology example
The Profinet network can be set up with a line structure. The following limits should be adhered to:
- Maximum 20 EP9300-0022 in series.
- No switches should be used in the line.
 | Use of switches without LLDP Profinet uses the LLDP protocol for the topology recognition. The topology recognition and the associated Profinet services will not work properly if the switch that you use does not support this. In addition, this results in increased network traffic, which is multiplied further with each switch port and connected Profinet device. This can result in communication disruptions and even the aborting of communication with individual Profinet devices. |
