PC Interface & Ethernet IP M/S conflict

JonKamstra

Hi all,

We usually purchase robots with the PC Interface option so that the robot can be connected to over a network. This works fine when we purchase the Profibus option for communication to other industrial devices but it seems when we  purchase the Ethernet IP Master/Slave option we can't set the IP address of the WAN port to the same network as the LAN3 port used for communication. 

Has anyone been successfully able to set the IPs of the WAN and the LAN3 to the same network range? IE. 123.456.789.1 and 123.456.789.2?

Thanks,

Hi
Below is from the Ethernet I/P application manual.

Intended use of WAN and LAN ports

The WAN port is a public network interface to the controller, typically connected to the factory network with a public IP address provided by the network administrator.

• 
  
• The LAN ports are intended for connecting network based process equipment to the controller, for example industrial networks, cameras, and welding equipment.
• 
  
•  LAN 2 can only be used as a private network to the IRC5 controller.
• 
  
•  Isolated LAN 3 or LAN 3 as part of the private network


The default configuration is that LAN 3 is configured as an isolated network.
This allows several robot controller to be connected to the same network, an alternative configuration is that LAN 3 is part of the private network.
The ports Service, LAN 1, LAN 2, and LAN 3 then belong to the same network and act just as different ports on the same switch.

This is configured by changing the system parameter Interface, in topic Communication and type Static VLAN, from "LAN 3" to "LAN". See Technical reference manual - System parameters.

Generally, the Spanning Tree Protocol doesn't permit two interfaces in the same range, but if you've done it elsewhere, then I may be way off-base.
