I have a question concerning network connectivity to a Compact Logix 5343 1768-L43 processor.
Some background information:
1) The 1768 PLC
a. IP Address is 192.168.1.16
b. Subnet Mask is 255.255.0.0
c. Gateway is 192.168.1.100
2) There is a touchscreen Windows computer that is an operator interface and communicates with the 1768 PLC
a. IP Address is 192.168.1.100
b. Subnet Mask is 255.255.255.0
c. Gateway is BLANK
3) Both of these are routed through a Allen-Bradley Stratix 6000 (1783-EMS08T) Managed Ethernet Switch
4) Currently this PLC is not connected to our local network. Our local network addressing scheme is as follows:
a. IP Addresses are 10.0.228.xxx
b. Subnet Mask is 255.255.254.0
c. Gateway is 10.0.228.1
5) I am working on a project that requires this PLC to be added to our network in order to communicate with another PLC. In order to accomplish this, it was suggested by one of our corporate techs to use an Allen-Bradley NAT Router (9300-ENA). I programmed it as follows:
a. Uplink Interface (Public)
i. IP Address: 10.0.228.18
ii. Subnet Mask: 255.255.254.0
iii. Gateway: 10.0.228.1
b. Local Interface (Private)
i. IP Address: 192.168.1.100 (per the explicit directions of the 9300-ENA this needs to match the Gateway of the 1768-PLC)
ii. Subnet Mask: 255.255.254.0
The communication was successful and I was able to get online with 1768-PLC. However, I ran into a problem. The touchscreen Windows computer lost its connectivity to the 1768-PLC with an IP address conflict. Because its IP address (192.168.1.100) matches the Local Interface IP address of the 9300-ENA, there is a conflict with two devices having the same IP address. I am guessing that the touchscreen Windows computer IP address has to match the Gateway of the 1768 PLC in order to communicate with it just as the 9300-ENA has to.
Do anyone know if there is any way to program either the 9300-ENA or the Stratix 6000 to accomplish having the 1768-PLC on our network or is there another device that can accomplish this while still preserving the connectivity of the touchscreen Windows computer?
