Panelview Plus 1250

Manufactured by Allen-Bradley, the PV Plus 1250 series is a series of controller and display terminals that feature internal CompactFlash Cards with firmware or operating systems and RAM. The PV Plus 1250 terminals feature the TFT color graphics displays that are programmed with a keypad, touchscreen, or a combination of both input types. The Allen-Bradley PV Plus 1250 terminals come with common features and firmware for providing easy unit migration to the larger displays. The units feature up to 8-wire resistive touchscreens with a high level of accuracy for the operator interfaces. Whenever a point on the touchscreen is pressed, the layers connect, changing the electrical current. The PV Plus 1250 units come with analog-resistive touchscreens and this applies to the touchscreen-only terminals or the combined keypad/touchscreen terminals.

The PV Plus 1250 terminal keypads feature function keys that are used for initiating the functions on the terminals’ displays. The units feature 12.1-inch display screens with color graphics support. They come with the Ethernet ports for controller communication. The devices feature status indicators that are used for monitoring the functionality of these devices. The terminals have the default switches that are used for performing operations like restoring the units to their factory default settings. The reset switches are used for resetting the terminals without the need for powering the devices on and off. The PV Plus 1250 terminals feature modular components that consist of a display module, a logic module, and an optional communication module. These components feature a flexible configuration and they are easy to install and upgrade.

Troubleshooting Your PanelView Plus 1250

PanelView Plus 1250 Incorrect Start-Up

If the PanelView Plus 1250 terminal is not starting up correctly always check for adequate power first. Inadequate power can cause a variety of unpredictable behavior. Simply verify the terminal's power requirement in the specifications table. It is also good practice to determine whether there have been any changes since the last startup. Determine what these are to see if they can be reversed.

Battery voltage, as well as the display temperature, are indicative of other potential issues as well. Check the battery voltage and display temperature from the PanelView Plus 1250 terminal desktop or from the FactoyTalk View ME station configuration mode. If the voltage is below 2.75 volts DC, consider replacing the battery. Obstructed airflow in the chassis can cause the CPU and/or display to overheat. If the CPU temperature is above 95 degrees Celsius or the display temperature is above 55 degrees Celsius, try to moderate the ambient temperatures.

If you continue have start-up issues, observe the splash screen for state messages and for the status or error codes. 

PanelView Plus 1250 Status Indicators

Status indicators are located on the back of your PanelView 1250 terminal. The COMM indicator is green and reflects communication. The FAULT indicator is red and reflects hardware faults. Upon startup, the fault indicator should be off and the comm indicator on. If the fault indicator flashes a few times at startup, this is not a concern. However, if both indicators are off you should check the power cable. See the table below to interpret the terminal's indicator status:

PanelView Plus 1250 Terminal Component Anomalies

If the PanelView Plus 1250 display lacks a touch screen, you may not have a touch screen display. Check the label on the terminal and the part number of the unit to verify. 

Please Note: When calibrating your touch screen, the process requires four (4) screen touches. If the touches are not satisfactory, more will be requested until calibration is successful. If the touch screen does not calibrate or continues to malfunction replace the PanelView Plus 1250 display module.

Isolating PanelView Plus 1250 Ethernet Issues

Indicator Status and Cable Connection/ Quality

Examine the status indicators at the Ethernet connector. If the indicator is green, a communication link is on. If the indicator is an amber color and flashing, this indicates data activity. You should always ensure there is a good connection to the hub and uplink ports. Poor cable quality and crimping can inhibit the ethernet connection. 

Ethernet Controller IP Address/ Conflicting IP Address

When in configuration mode select Terminal Settings> Networks and Communications > Network Connections > Network Adaptors. Check the DHCP. If this is enabled the device will attempt to connect to a valid IP address within seconds of startup. If it fails to acquire and IP address, the TCP/IP protocol will assign 169.254.xxx.xxx. If the DHCP is not enabled, verify the IP address specified does not conflict with another device on the network. 

Verify Device Name

Other devices must not share the same hostname if they are on the same network. When in configuration mode, select Terminal Settings> Communications and Networks> Network Connections> Device Name. 

Peer or Server Settings

The Ethernet issue may be caused by the other side of the connection.
