7. Add a new program: In the project tree, right-click on the Programs folder and select "Add New Program." Give the program a name and select the controller to which the program will be downloaded.

8. Write the program: You can now start writing your program in the ladder logic or structured text language. Use the instructions available in the RSLogix 5000 software to write the desired logic.

9. Test and debug: Once the program is written, you can test it by going to the online mode and going online with the controller. Use the monitoring and debugging tools available in the software to troubleshoot any issues in your program.

10. Download the program: After testing and debugging, you can download the program to the 1756-EN2TR controller by clicking on "Download" in the RSLogix 5000 software.

11. Test the program: After the program is downloaded, you can test it on the actual hardware to ensure it is functioning as desired.

12. Save the project: Once everything is working correctly, save the project and make a backup copy for future use.

Congratulations, you have successfully programmed the Allen Bradley 1756-EN2TR PLC! 

Troubleshooting tips for Allen Bradley 1756-EN2TR Ethernet/IP module.

1. Check the LED status: The EN2TR module has several LED indicators that provide status information. Make sure that the power LED is lit, indicating that the module has power. The link status LED should also be lit, indicating that the module is connected to the network.

2. Verify network settings: The EN2TR module is typically configured using the RSLogix 5000 software. Make sure that the network settings, such as IP address, subnet mask, and gateway, are correct and match the settings of other devices on the network.

3. Perform a self-test: The EN2TR module has a built-in self-test feature that can help identify any internal hardware issues. To perform a self-test, press and hold the Test button on the front of the module for 5 seconds. The module should briefly disconnect from the network and then reconnect. If the test fails, contact Allen Bradley technical support for assistance.

4. Check the firmware version: Make sure that the firmware version of the EN2TR module is compatible with the firmware versions of other devices on the network. If not, update the firmware to the latest version.

5. Check network cabling: Make sure that the Ethernet cable is securely connected to both the module and the network switch. Use a cable tester to verify the integrity of the cable. If possible, try using a different cable.

6. Consider network congestion: If there is heavy network traffic, the EN2TR module may have trouble communicating. Try adjusting the scan time of the module in the RSLogix 5000 software to reduce network congestion.

7. Check for duplicate IP addresses: If two devices on the same network have the same IP address, it can cause communication issues. Make sure that there are no duplicate IP addresses on the network.

8. Disable firewalls: If there are firewalls or security software on the network, temporarily disable them to see if they are blocking communication between the module and other devices.

9. Reset the module: If none of the above troubleshooting steps resolve the issue, try resetting the module by removing the power for 30 seconds and then reconnecting it. This will reset the module's internal settings and may resolve the issue.

10. Contact technical support: If the issue persists, contact Allen Bradley technical support for further assistance. They may be able to provide more specific troubleshooting steps or recommend hardware replacement if necessary.
