The Industrial Raspberry Pi Forum

Hello everyone,

I want to use one RevPi Connect as a Profinet master and another one as Profinet Slave. The master has eth0 static ip: 192.168.0.100/24, eth1 static ip: 192.168.0.101/24. While the slave has eth0 static ip: 192.168.0.1/24, eth1 static ip: 192.168.0.2/24. There is an eth cable connected between master eth1 port and slave eth1 port.

if I connect PC to the master eth0 port. The ping to the master eth1 port is successful. However ping to slave eth1 port failed.
if I connect PC to the slave eth0 port. The ping to the slave eth1 port is successful. However ping to master eth1 port failed.

How can I make it possible to access slave eth1 port via master eth0 port and vice versa?

Thank you for your help.

Hi Cloud,

how exactly do you implement the PROFINET master and slave?

Our proposal: Implement the PROFINET master with Codesys and use a PROFINET IRT Gateway (https://revolutionpi.de/gateway/) for the slave. Example for CODESYS with a PROFINET IO Controller and a PROFINET IRT Gateway --> https://revolutionpi.com/tutorials/beis ... t-gateway/

Does this information help you?

Best regards
Stefan

Hello Stefan,

I ordered a Profinet IRT Gateway but it is still on the road. So currently I am just using two RevPi Connect for a test. Without considering the application in Codesys, I first set the static ip on both devices and make a ping test between two devices. Then I encountered the above question.
