This is the first time I've experienced this issue. A colleague, who specializes in controls, compiled the project into a .mer file and downloaded it to the PanelView Plus 7. However, I encountered a communication driver error. Upon receiving a prompt asking, "Load anyway? Yes/No," I selected 'No,' which sent me back to the terminal menu. After resetting the terminal, the communication driver error reappeared. This time, I chose 'Yes' out of curiosity, and surprisingly, the project loaded successfully and functioned without problems. While I’m relieved that it works, I’m concerned that I haven’t resolved the underlying issue. Does anyone have any insights on this? I have already checked the settings in RSLinx Enterprise and the Communications tab. Would upgrading the firmware be a recommended solution? Thank you!
The warning you're encountering likely indicates that there's a CPU within the communication schema that is incompatible with the terminal's current firmware. When you ignore this warning, the system functions correctly because the newer CPU lacks any communication-specific features that could cause conflicts. To eliminate this error message, I concur that upgrading the firmware of the PV+ terminal is the most effective solution.
Thank you, Ken. It turns out that the controller was mistakenly set up as a 5370 model, whereas it is actually a 5330. I appreciate your assistance, sir.
