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.
When attempting to establish a connection with certain devices, Andy Patel discovered that the option to upload an EDS file was only available for connected devices. This feature is particularly useful for later Rockwell Automation devices when a connection is established but the computer lacks the necessary firmware. Despite appearing as though there is no connection, the device is actually listed in the RSlinx's Ethernet connection table, as stated in the initial forum post.
Could you take a screenshot of your RSlinx window and share it in the comments section? Don't forget to include details about the channel configuration you are currently using. This information will help in troubleshooting and providing assistance.
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
