Hello, I hope i chose right category.

I'm working on a project that involves communication between AXC F 2152 controller and Raspberry Pi 3 (only one at the moment, but in future i would like to communicate with few Raspberry Pi 3). I have FL WLAN EPA - WLAN Ethernet Port Adapter, which i have to use in this project, to able communication between the controller and raspberry Pi (so both devices can communicate wirelessly). I have a problem at the stage of communication between PCWE and PLC.  I have PLC and my computer connected with Ethernet cable. When I create a blank project and try to find the PLC using 'Scan the network' button in Online devices tab, the PCWE doesn't find it (I'm sure i set IP Range in Settings tab correctly). When I use AXC F 2152 template in PCWE i can't find the device either, but when i go to the Settings tab of AXC F 2152 and change IP address assignment mode to Manual and write the PLC default IP Adress below (192.168.1.10) i can connect to the controller from the Cockpit tab (using 'Connect to the controller...' option, and after logging in as admin with default password). Has anyone got a clue what might be the case? I can find the device using Advanced IP Scanner, i can access the WBM, and i managed to install new firmware using WinSCP, but somehow PCWE doesn't see the PLC. I tried all the solutions i could find on this forum and nothing helped

 

And as I mentioned in the beginning, I want to establish a wireless connection between PLC and Raspberry PI using FL WLAN EPA adapter. Is this possible using this adapter? I couldn't find any info on this adapter or examples of usage apart from the manual so I would be grateful for any advices.

Hello,

Some things that may stop the PLC from being found by the Scan function:

1. In the "Project" window, please make sure that the correct Ethernet adapter has been selected (the screen shot below is from my machine - you need to pick the network adapter that is attached to your PLC).

2. If you have a firewall installed on the network or on your PC, then this may block discovery messages.

3. If the PLC is located on a different network, discovery messages might not get through the router. If you have a direct cable connection to the PLC, then this should not be a problem.

4. The discovery service uses a Profinet protocol - this is enabled by default, but it is possible to disable it. (this is usually done to stop the BF-C and/or BF-D LEDs from flashing when there is no Profinet network required). But I'm guessing you haven't changed this setting in your PLC.

Please let us know if any of this helps.

On the question about the FL WLAN EPA:

Yes, it is possible to use this Ethernet Port Adapter to connect the AXC F 2152 to a WiFi network. The information in the EPA user manual should be enough to set up the adapter, but if not then additional support for this device can be provided through the Phoenix Contact subsidiary in your country.
