EK9300 PROFINET topology sample
EK9300
The construction of the EK9300 can take place in a line, with adherence to the following points:
- Maximum 20 couplers one behind the other
- 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. The effects of this can be communication errors extending up to the aborting of communication with individual PROFINET devices. |
