Troubleshooting Common Issues with PanelView Plus 6 Terminals

PanelView Plus 6 Terminals are integral to industrial environments as they provide essential interfaces for human-machine interaction. However, like any equipment, they may encounter issues that need troubleshooting. Here's an in-depth guide to addressing some of the most common problems you might encounter with these terminals.

1. Terminal Does Not Power Up

A non-responsive terminal can be one of the most frustrating issues. Here's how you can troubleshoot:

• Improper connection to power source: Verify all wiring and connections to ensure the terminal is correctly connected to the power source.
• Incorrect input voltage level: Ensure that the correct voltage level is present at the power terminals. Incorrect voltage can prevent the terminal from powering up.
• DC power wires reversed: For DC terminals, ensure that the positive and negative wires are connected to the appropriate terminals.
• Power terminal block not fully seated: For PanelView 300 terminals, ensure that the power terminal block is securely attached to the base of the terminal.

2. Application File Will Not Download

If you're experiencing issues downloading application files, consider the following steps:

• First Download:
  • Ensure that the communication cable is correctly connected.
  • Check that both the computer and the terminal have the same communication settings and rate.
  • Verify the correct COM port selection on your computer.
• Subsequent Downloads:
  • Verify that the communication or communication rate settings between the terminal and computer are consistent.
  • Adjust settings if required in the Communication Setup screen of the terminal.

3. No Communication with Controllers

For issues where the terminal does not communicate with MicroLogix, ControlLogix, SLC, or PLC controllers, follow these steps:

• Communication fault: Check the status of the COMM Status indicator.
• Cable connections: Ensure all cable connections are secure according to the diagrams provided in the manual.
• Communication rates: Verify that the terminal and the controller are set at the same communication rate.
• Controller run mode: Make sure the controller is in run mode.
• Node numbers: Check that the terminal node and maximum node numbers are set correctly.

4. No Communication with PLC Despite Active COMM Status

If the terminal's COMM status is active but there's no PLC communication, consider these solutions:

• Address mismatch: Confirm that the PanelView terminal is trying to communicate with the correct controller address.
• Inhibit bit setting: Verify and adjust the inhibit bit setting on the Channel Status Screen in the PLC.

5. No Communication with Computer

When the terminal fails to communicate with a computer, check the following:

• Communication fault: Check the COMM Status indicator.
• Cable connections: Use the cable diagrams in Chapter 10 of the user manual to verify the connections.
• DH-485 port connection: Ensure that there is a proper SLC, network, or power supply connection at the terminal's DH-485 port. The Personal Computer Interface Converter (PIC) receives power from the DH-485 connection. Verify that the terminal is connected correctly as shown in Chapter 12 of the manual.
