Hello,
I have an AXC F 3152 controlling several devices on a ring profinet network.
I also have an AXC F 2152 controlling other devices.
How can I exchange data between these two PLC’s through the profinet network?
Grateful for the attention.
Hello,
one of the PLCs must be integrated as Profinet device into the PLCnext Engineer project of the other PLC.
On the „device PLC“ you can use the system variables PND_S1_INPUTS and PND_S1_OUTPUTS to exchange data with the „controller PLC“.
On the „controller PLC“ you can use the process data of the „device PLC“ DI4096 and DQ4096.

Hi , I am doing it with two AXC F2152, How can i transfer my variables from the controller to the device, could you help me ?
PN_DataExchange.zipHi, as described above on the controller you integrate the other PLC as Profinet device and use the process data of that device. On the PLC which is integrated as device you can use the existing system variables and assign your variables to them. I have attached a sample project for each device.
There is also a step-by-step guide in the PLCnext Info Center, for exactly this scenario:
Configuring PROFINET controller and device This series of steps demonstrates how to set up communication between two PLCs, one of them being the PROFINET® controller and the other being the PROFINET® device.
Thank you very much

Does this procedure also work if I have 1 AXC F 3252 controller and 2 AXC F 2152 devices?
Yes, identical.
Just be sure to use the correct Ethernet interface on the Controller (X2).
