Greetings everyone, I am currently utilizing an Ethernet Driver and have manually inputted IP addresses. While I can successfully ping certain IPs in the command prompt, RSLinx shows them with a yellow question mark and a red cross, indicating they are unrecognized devices. Can anyone shed light on why this discrepancy is occurring and offer solutions to rectify the issue? Thank you, Andy.
If you are unable to identify a device in RSLinx, it may be due to the lack of EDS files installed. Typically, you can download these files from the manufacturer's website and install them using Rockwell's EDS Hardware Installation Tool. If you see a red cross, it indicates a failed connection, while a yellow question mark may mean a connection has been established but the device cannot be identified (in this case, adding an EDS file is necessary).
Are you having trouble adding a device to RSLinx? The presence of a red X indicates that RSLinx is unable to detect the device or that it is not compatible with Ethernet I/P. For instance, if you try to add an IP camera to the Ethernet Devices driver, it may appear with a red X even if it is connected to the network and responding to pings.
plvlce mentioned that the absence of EDS files in RSLinx is causing difficulty in identifying devices. It is recommended to download the necessary EDS files from the manufacturer's website and install them using Rockwell's EDS Hardware Installation Tool. A red cross indicates a failed connection, while a yellow question mark signifies a connection without device identification, requiring an EDS file. Despite attempting this solution, the issue persists with compact Logix PLCs in RSLinx, even though other similar PLCs are being recognized. Any suggestions on resolving this issue?
These PLCs have firmware versions beyond the EDS files you currently possess. To update in RSLINX, simply right-click and upload the EDS files directly from the devices for installation.
When dealing with PLCs that have newer firmware versions than the EDS files you have, it is important to update the EDS files in RSLINX. Simply right-click on the devices and select the option to upload the EDS file from them. However, note that this option may only appear for devices that are already connected.
Hey Andy, this is a common issue and usually indicates that RSLinx is having trouble communicating with the device, even though your network setup is correct. The yellow question mark means the device is detected but not responding to the identity object query. And a red X typically means RSLinx is not able to exchange data with the device. The solution could be multifaceted, one possibility is ensuring your devices are compatible with RSLinx. It could also be a firewall issue where RSLinx doesn't have the required permissions. Try disabling your firewalls temporarily to see if that resolves the issue. Also, ensure that your Ethernet driver is up-to-date and that you're running the latest version of RSLinx. Good luck!
Hi Andy, the yellow question mark usually indicates that RSLinx can see the device on the network, but can't identify what it is, while the red cross typically suggests a communication error. It sounds like there might be a firmware mismatch or possibly issues with your Ethernet setup. I'd recommend first verifying if all the devices are supported in the version of RSLogix (and if not, you might need to update or install an EDS file). If that doesn't solve the problem, the issue could be with your physical network (cabling, switches, etc.) or firewall settings as well. Remember, just because a device is pingable does not necessarily mean it's accessible to RSLinx.
Hey Andy, it sounds like you might be dealing with a compatibility issue or misconfiguration in RSLinx. Have you checked if the Ethernet driver in RSLinx is set up correctly for the devices you're trying to connect to? Sometimes, it helps to ensure that the correct subnet mask and gateway are configured as well. Additionally, make sure that the devices are on the same network as your PC and that there are no firewall settings blocking communication. You could also try refreshing the driver or reinstalling it if the issue persists. Good luck!

Answer: 1. Why does RSLinx show unrecognized devices with yellow question marks and red crosses despite successful pings in the command prompt? - This could be due to RSLinx not being able to properly communicate with the devices even though the IP addresses are reachable through ping. It may indicate a configuration or compatibility issue between RSLinx and the devices.
Answer: - One solution could be to double-check the device configuration settings in RSLinx to ensure they match the actual settings of the devices. It's also recommended to verify network connectivity and firewall settings that might be blocking communication between RSLinx and the devices.
Answer: - Yes, you can start by verifying the IP addresses, subnet masks, and gateway settings of the devices. Additionally, checking for any duplicate IP addresses, ensuring proper network connectivity, and reviewing RSLinx configuration settings can help pinpoint the root cause of the issue.
Answer: - Yes, firewalls or security software settings can sometimes interfere with the communication between RSLinx and the devices. Make sure to configure any firewall or security
