Hi all,

I have Rasp Pi 3 Model B and need to do the control of asynchronous drive (SIEMENS) which is connected to control unit (SIEMENS) and I have Ethernet cable which I should connect to Raspberry Pi. I use software CODESYS Control for Raspberry Pi SL, and I have problem to in a communication between Pi and control unit. Please suggest is this project possible, do I need any additional hardware? I haven't seen projects which connect Siemens hardware with Codesys software, could this cause a problem?

Thank you in advance!

Hi,

here is an example project how to use the Pi as Profinet device.

PN Controller is possible to, add Ethernet then PN Controller.
So both is possible. (Master/Slave)

Hi,

Thank you for your reply.
I connected everything, but I have a problem now that I cannot see any inputs/outouts from control unit. When I go online "User-defined parameters" list is empty.
What could be the reason for this?
I updated GSDML file from Siemens to Codesys.

Hi,
screenshot, or attach the project.
Otherwise almost impossible to help.
