Troubleshooting PanelView C300 Display Issue: Communication Protocol Error with Asterisk (*)

Question:

In the process of troubleshooting a PanelView C300 display for a customer, it was discovered that the device, manufactured in 2014, is not being recognized by Linx. The communication configuration on the terminal is displaying an asterisk (*) with a Node address of 0, and attempts to modify the node result in an error. Despite flashing the firmware to version 1.80, the issue persists. There seems to be no straightforward way to perform a factory reset on these devices.

While I cannot guarantee the same for the C300 model, I can confirm that newer panel views require network connectivity to display IP/communication activity. If the Ethernet connection is disconnected, these displays will show zeros.

In regards to the C300, it is uncertain, but it is known that newer panel views require network connectivity to display IP communication activity. If the Ethernet connection is disconnected, the displays will show zero activity. Please note that this is referring to serial communication, not Ethernet.

If you find yourself in a situation where you are stuck and need to reset your unit to its defaults, follow these steps: 1. Connect a USB keyboard and hold down CTRL-SHIFT while powering up the unit until you see a prompt about resetting to defaults. Press F1 to confirm. 2. Once the unit has rebooted, insert a USB stick with the latest firmware version (1.80) and power cycle the unit to install the update. 3. Finally, transfer the project file. After completing these steps, my communication protocol now displays as DF1. This troubleshooting process can be useful for resolving technical issues and updating firmware version.

It sounds like you've already tried some solid approaches with the firmware flash and attempting to modify the node. The asterisk usually implies that the PanelView is in a faulted state or it's not able to communicate. I've encountered a similar communication issue before - is your device connected directly to a PC or through a gateway? If it's through a gateway, ensure all devices are using the same communication settings. You could also try testing it on a different PC to rule out any specific computer-related issues. For a factory reset, while PanelView C300 doesn't offer a straightforward button combination, you can attempt a reset by removing and reapplying power while making sure to back up any important data beforehand.

It seems like a challenging issue you're dealing with and PanelView C300 is indeed a tricky piece of equipment. However, have you tried to assess the RSLinx software side? It might be that there is some misconfiguration within, as it's responsible for identifying and enabling connectivity with the device. Also, check for any hardware damage in case it's a physical issue that's preventing the changes. Just make sure you have back-ups before any troubleshooting processes are undertaken. As for the factory reset, unfortunately, it's true that these devices don't have an overly explicit method, but contacting Rockwell's technical support should hopefully provide some assistance.

It sounds like a frustrating situation with the PanelView C300! Since you're seeing the node address as 0 and can't change it, it might be worth checking the physical connections and cables for any signs of wear or damage. Sometimes, a loose connection can cause recognition issues. If everything looks good there, have you tried using different ports or switching the communication method? Also, if there's a chance to check with Rockwell support, they might have troubleshooting steps specific to older devices like this one. Good luck!
