Hi NCD community,
I have bought two industrial relay controller 8-relay with ethernet (ncdwebi) for work with. This board seems to be awesome. Unfortunately, I am not able to connect via static IP.
The connections with DHCP via a router seems to be unprolematic.
The web interface is pretty cool. The NCD config tool and the COMM Operator works.
However, I have changed the connection settings to static IP with the same properties as in the DHCP properties. After connecting directly with the laptop, I can’t connect to the relay card. The NCD Base SW recognize the relay card, but can’t connect to it.
I really don’t recommend a direct connection with a laptop. Do you have an unmanaged switch you could put between your computer and the controller? Or just an unmanaged router?
thanks for the fast answer
For the pictures above, I have tried with a managed router. As the Test Box I am developing limits my hardware space, I would prefer a direct connection to the mini PC in the Test Box.
Out of interest: why it would work with a unmanaged switch but not with a direct connection to the PC.
I’m gonna look for an unmanaged switch and will test it.
I have more Test Setups in planning. So if it gonna work well, I will purchase some more industrial relay cards
Best regards
Minh
P.S.: The description mentions a direct connection to the PC if I use the jumper. I thought after setting a static IP I could also control a board via a direct connection with a PC. Are my settings mentioned above not OK ? (wrong gateway maybe or so?)
just figured out how to connect the relay card directly with the Laptop.
1.: Connect Relay card with switch and PC in order to read the settings.
2.: Start NCD Config Tool and get the IP adress on the top left side, the Subnetmask and all the other Settings
3.: Connect Relay Card direcly with PC.
4.: Start NCD Config → Use the Follow IP Adress
5.: Fill in the Settings: IP adress as reas before in NCD (change the last number e.g. xxx.xxx.xxx.36 to xxx.xxx.xxx.44); Subnetmask as read before; Gateway as read before (change the last number to .1); DNS as read before
6. Apply Settings
7. Tap the xxx.xxx.xxx.36 to your Browser
