Technical FAQs

Q1: What is the primary function of the Foxboro P0924WV?

The P0924WV is a USB annunciator and numeric operator keyboard designed for Foxboro I/A Series DCS workstations. It provides alarm indication, audible notifications, numeric input and programmable macro operations.

Q2: What is the difference between the P0924WV and a standard computer keyboard?

Unlike a conventional keyboard, the P0924WV incorporates dedicated alarm annunciator keys with individual LED indicators, alarm control buttons and programmable macro functions. It is specifically designed for industrial DCS operator interaction.

Q3: How does the LED alarm indication function work?

The workstation software controls the individual LED indicators according to configured process conditions. Each supported indicator can display red, yellow, green or off states, with flashing behavior available for alarm notification.

Q4: What is the purpose of the Silence Horn button?

The Silence Horn button allows operators to silence the audible alarm signal when an alarm occurs. It helps reduce unnecessary noise while allowing operators to continue monitoring the corresponding visual alarm indications.

Q5: What does the Lamp Test button do?

The Lamp Test function illuminates the LED indicators simultaneously, allowing maintenance personnel to check the operation of the annunciator lights and identify defective indicators.

Q6: Can the P0924WV be connected through a USB hub?

Yes. It can connect directly to a workstation USB port or through a suitable USB hub. The connection must comply with the system's USB requirements. It cannot be connected through a Remote Graphics Unit (RGU).

Q7: Can the P0924WV operate together with a serial/GCIO annunciator keyboard?

No. The workstation supports either a USB annunciator keyboard or a serial/GCIO annunciator keyboard, not both simultaneously. A workstation configured for the P0924WV also has restrictions regarding serial card and GCIO interface module installation.

Q8: What operating systems support the P0924WV?

The documented operating system support includes Windows 7 and Windows Server 2008 R2. Compatibility should be checked against the installed I/A Series workstation software and hardware configuration before deployment.

Q9: What should technicians check if the keypad is not recognized by the workstation?

First, inspect the USB cable and connection port. Then verify that the workstation recognizes the connected device, check the supported operating system and software configuration, and confirm that the USB connection is not routed through an unsupported interface.

Q10: What should be checked if the LED indicators or keys do not respond correctly?

Use the Lamp Test function to verify the LED indicators, inspect the USB connection and check the workstation configuration. If individual keys remain unresponsive, further inspection of the keypad hardware and associated software configuration may be necessary.
