I recently learning Codesys V3.5. I use PC( Win V3 ) or raspberry pi3 to run the Codesys program.
I have successfully used EtherCAT and Modbus TCP protocol to communicate with the Staubli robot.
But Profinet always does not work.
When I use PC( Win V3 ) as Profinet Controller, the status bar tells me that there is no module.
When I use RaspBerryPi3 as Profinet Controller, All status lights are green.But communication is still not successful

Hi,

for Profinet on Control Win there are two points needed:
1. Install Winpcap (Winpcap.org)
2. Disable the Firewall

then it should work

When I use RaspBerryPi3 as Profinet Controller, all status lights are green.But communication is still not successful
either use the inputs/outputs in the pou's (add mapping) or set "Enable 2 update variable.." option.

RaspberryPi3: Profient Controller
StaubliRobot: Profinet Device

Currently I can monitor the robot to Raspberry Pi3 digital input signal.
Raspberry pi3 output signal in the robot side is always a question mark “？”

I use SIEMENS s7-1200 instead of raspberry pi3 communication with robot is OK.
So..I don't think the problem is on the side of the robot.

When I scan for devide. It picks up the correct IP, stationname and MAC.

But I do not understand that valid IP required.
