Gateway configuration not transferred to controller?

PLCNext Engineer 2020.0 (Build 4.0.250.0)
Controller: AXC F 2152, FW 2020.0 LTS (20.0.0.24752):

I've configured a static IP address: 10.2.3.213 / 255.255.255.0 / 10.2.3.1 but couldn't reach PROFICLOUD or any other external IP address. I logged on to the controller via ssh to check the /etc/network/interfaces file. The device address and mask were correct but the gateway address said 0.0.0.0 and had obviously not been transferred from PLCNext to the controller. After I corrected the interfaces file manually and restarted the system everything worked as expected. Funny thing?

Regards, Wolfram

    Hi Wolfram,

    I create several new PLCnext Engineer v 2020.0 projects every week, all with a non-default Gateway address, and I have never had this problem, but that's not to say that it's not possible.

    Can you please confirm that this is reproducible behaviour, if so then I will pass this to the PLCnext Engineer team, and they will let you know what additional information they need from you to investigate further.

    Yes, it seems to be a reproducible behaviour.

    I just configured a new gateway address like this

    address 10.2.3.213

    subnetmask 255.255.255.0

    gateway 10.2.3.2

     

    and uploaded it to the controller.

    Logged on with SSH and using ip r I've got this:

    root@axcf2152:/opt/plcnext/# ip r
    default via 10.2.3.1 dev eth0
    10.2.3.0/24 dev eth0 scope link src 10.2.3.213
    root@axcf2152:/opt/plcnext/#

    The gateway address did not change from 10.2.3.1 to 10.2.3.2. Where am I wrong?

    Hi Wolfram,

    OK, I have reproduced what you are seeing, and this was my misunderstanding.

    Using PLCnext Engineer, it is only possible to change the IP parameters of the PLC using the Project -> Online Devices window:

     

     2020 03 10 13 10 58

     

    This is way I have been setting the Default Gateway in my projects, so I misunderstood the problem (sorry!).

    It is not currently possible to change the default gateway by downloading a new PLCnext Engineer project to the PLC. From PLCnext Engineer, this can only be done from the Online Devices window.

    Thank you Martin - I got it!

    I assumed new IP settings are transferred with an upload as it is the case with Siemens PLCs, for example.

    Yeah, this isn't clear in PLCnext Engineer. Hopefully this will improve in a future version.
