Hi

To communicate using Ethernet/IP between Siemens S7-1500 and Omron NX1120, you need to configure the communication settings on both devices. Here is a step-by-step guide:

1. Configure the IP address of both devices: You need to assign a unique IP address to both devices in the same subnet range. For example, if the Siemens S7-1500 has an IP address of 192.168.1.10, then you can assign 192.168.1.20 to the Omron NX1120.

2. Configure the Omron NX1120 as the adapter: In the Omron NX1120, you need to configure it as an adapter device, which means it will accept the connection requests from the scanner (Siemens S7-1500). Go to the "Ethernet/IP Settings" menu in the Omron NX1120 and select "Adapter" mode.

3. Configure the Siemens S7-1500 as the scanner: In the Siemens S7-1500, you need to configure it as a scanner device, which means it will initiate the connection requests to the adapter (Omron NX1120). Go to the TIA Portal project for the Siemens S7-1500 and configure the "Ethernet Global Settings" with the IP address of the Omron NX1120 and set the "Connection Type" to "TCP/IP".

4. Configure the I/O mapping: After completing the above steps, you need to map the I/O data between the Siemens S7-1500 and Omron NX1120. This involves creating tags or variables in the Siemens S7-1500 that correspond to the I/O data in the Omron NX1120.

5. Test the communication: Once the configuration is complete, you can verify the communication by monitoring the I/O data exchange between the two devices.

Note that the exact steps may vary depending on the specific models and software versions of the devices. You should consult the documentation provided by Siemens and Omron for detailed instructions on how to configure Ethernet/IP communication between their devices.
