Hello everyone, I am attempting to establish a connection between an SLC 5000 and an SLC 500 PLC using Ethernet for communication. The SLC 5000 is equipped with a 1756en2t Ethernet card installed on the rack, visible in RS LINX along with the SLC 5000. Similarly, when connected to the SLC 500, the PLC is also visible in RS LINX. I have connected an Ethernet cable between the 1756en2t on the 5000 rack and the SLC 500, as well as between my laptop and the Ethernet port on the SLC 5000 CPU. However, I can only see the SLC 500 PLC and the Ethernet card. I expected to see the SLC 500 PLC through the 1756en2t card. Is there something I may have overlooked or not properly configured? Shouldn't I be able to see the SLC 500 PLC in RSLINX when connected to the 5000 PLC? All devices, including the two PLCs, the Ethernet card, and the laptop, are on the same network with IP addresses like 192.168.36.xxxx.
When it comes to remote devices connected via backplanes, they will not be automatically detected. To browse these devices, simply right-click on the "Ethernet" sub-item located under the 1756-EN2T module, navigate to Properties, and manually input all the IP addresses that you anticipate to view. This step is crucial for gaining access to devices connected remotely over a network.
In the world of industrial automation, remote devices connected over backplanes do not automatically appear. To rectify this, you can right-click on the "Ethernet" sub-item located under the 1756-EN2T module, navigate to Properties, and manually add all the IP addresses you anticipate to be visible on the network. Thank you Imscar12 for your assistance; I truly appreciate it! I will be sure to give that a try tomorrow.
When setting up a SLC 5/05, it's important to ensure you have the correct IP addresses and subnet addresses for all devices on the network. If the SLC shares the same IP address as the 5000, you'll need to make adjustments to avoid conflicts. Utilizing tools like Angry IP Scanner can help identify any conflicts. Have you configured the SLC 500 in the 5000 yet? Remember to add the IP address to Linx for seamless integration. - James
When setting up remote devices over backplanes, keep in mind they may not be automatically detected. To ensure all devices are visible, right-click on the "Ethernet" sub-item under the 1756-EN2T module, access Properties, and input all the relevant IP addresses. I have checked and configured all necessary IP addresses for my devices, including my laptop, SLC 5000, SLC 500, and the 1756-EN2T card. These configurations were made within the properties of the Ethernet driver in RSLINX.
James Mcquade inquired about the IP addresses and subnet addresses of devices using a SLC 5/05. It is important to ensure that the SLC and other devices have unique IP addresses to avoid conflicts. Utilizing tools like Angry IP Scanner can help identify any conflicts on the network. In my setup, I am working with an SLC5/05 and a SLC 5000 with the following IP addresses: 192.168.136.30 for 1756en2t, 192.168.136.29 for SLC5000, and 192.168.136.8 for SLC 5/05. Additionally, the laptop Ethernet adapter has the IP address 192.168.136.40. I have established communication with both PLCs individually in RSlinx, but there seems to be an issue with them not being able to see each other using the 1756en2t card. This setup is being tested before implementing any changes in the field, making it a simple setup with just two PLCs and a network card.
It sounds like you've set up the connection appropriately, but you may want to double-check few things. First, ensure the 1756-EN2T card is properly configured and the IP addresses for all devices are correctly assigned within the same subnet. Next, verify that the 1756-EN2T card and the SLC 5000 are in the same RS LINX network by examining the RSWho screen - it's easy to accidentally place them in separate networks. Lastly, confirm that there are no firewalls or security protocols causing restrictions. If you've checked all this and you're still not able to view the SLC 500 PLC through the 1756-EN2T card, I'd advise seeking onsite support – sometimes, these issues can be due to hardware faults.
It seems like you've done a good job with the physical connections and ensuring all devices are on the same network. However, you might want to check the configuration of your RS Linx. Be sure that the Ethernet Driver is properly set up in RSLinx since that's how it communicates with your PLC. Also, a key aspect to check is the timing parameters - RPI (Requested Packet Interval) on your 1756-EN2T Ethernet card. Incorrect RPI settings could result in communication gaps. Additionally, I'd recommend checking if your SLC 500's communication port is properly configured for Ethernet communication and not just serial.
It sounds like you already have a solid setup. But if you're still having issues with visibility, I'd suggest double-checking the communication driver setting in the RS LINX. Ensure it's correctly configured to communicate via the Ethernet/IP driver. Also, ensure that the PLCs and the Ethernet cards are in the same subnet. If not, it may lead to communication issues. It might also be useful to manually enter the IP addresses of the devices into RSLINX, rather than relying solely on the automatic device discovery feature. Keep us updated on your progress, and we're here to help!
Yes, you should definitely be able to see the SLC 500 PLC in RSLINX when it's connected to the 5000 PLC, given your setup. As per the initial troubleshooting, you can check the IP configuration and the subnet mask of each device to make sure they're correctly configured. Also, do ensure that there's no IP address conflict between your devices. Alternatively, double-check the firmware of your 1756en2t Ethernet card, as an outdated firmware may cause this type of issue. Lastly, you might want to check your firewall settings as they could potentially block the connection between the PLCs. If none of this helps, you might need to get in touch with Rockwell support for a more detailed diagnosis.
