PRO-FACE AGP3400-T1-D24 HMI GP3000 7.5 Inch Touch Panel

Description

Product Introduction & Engineering Value

A machine operator interface failure can stop production faster than many mechanical faults. When an older HMI reaches end-of-life, replacing it without considering project files, communication drivers, and panel dimensions can create unnecessary downtime.

The PRO-FACE AGP3400-T1-D24 is a GP3000-series touch panel designed for industrial operator control applications. It provides a VGA touchscreen interface with multiple communication options, including Ethernet and serial communication ports.

For retrofit projects, the key identifiers are AGP3400-T1-D24 and PFXGP3400TAD. The model has been discontinued, and Pro-face provides replacement guidance toward newer HMI platforms for migration planning.

Technical Specifications

The AGP3400-T1-D24 specifications include a 7.5-inch TFT display, VGA resolution, DC24V operation, Ethernet, USB host, serial communication, and CompactFlash support.

Field Application & the “Trench” Experience

A packaging machine running continuously for more than a decade develops an HMI display problem. The touchscreen still responds, but the backlight is dim and the operator cannot reliably read alarm messages during production.

The maintenance team identifies the installed unit as PRO-FACE AGP3400-T1-D24. Instead of immediately redesigning the machine interface, they verify:

1. Existing GP-Pro project backup.
2. PLC communication driver.
3. Panel cutout dimensions.
4. Ethernet and serial wiring.
5. Replacement HMI compatibility.

The original unit is replaced during a planned maintenance window. The machine returns to operation without changing the PLC program.

Typical applications include:

• Packaging machine operator panels
• CNC machine monitoring interfaces
• Factory automation equipment control stations
• Marine and transportation control consoles

Transparency SOP: QA & Testing

For a legacy HMI, inspection must cover both display hardware and communication functions.

QA Checklist

Hardware Verification

• Confirm model label: AGP3400-T1-D24
• Verify global code: PFXGP3400TAD
• Inspect touchscreen surface
• Check LCD condition
• Inspect mounting frame and connectors

Power Testing

• Apply regulated 24VDC supply.
• Verify startup sequence.
• Check display brightness and touch response.
• Monitor abnormal current consumption.

Communication Testing

• Verify Ethernet port operation.
• Test serial communication channels.
• Confirm PLC communication where possible.
• Check CompactFlash access.

Software Verification

• Confirm GP-Pro EX compatibility.
• Test screen navigation.
• Verify alarms, trends, and data display functions.

The Veteran’s Tech Trap Guide

⚠️ Do not assume any 7.5-inch Pro-face HMI is a direct replacement.
The physical size may match, but communication drivers, project conversion requirements, and hardware features can differ.

⚠️ Backup the GP project before removing the old unit.
A replacement display without the original project file can turn a simple hardware swap into a full redesign task.

⚠️ PRO TIP: Check the suffix carefully.

is different from:

• AGP3400-S1-D24
• -FN1M
• -CA1M

These variants may include different interface options.

⚠️ Do not ignore battery and memory condition.
Legacy HMIs may contain backup memory components that affect retained data and application recovery.

⚠️ A working display does not guarantee a healthy HMI.
Communication ports, touch calibration, CF storage, and internal memory should all be verified.

Dynamic FAQ

Q1. What isACE ?

ACE is a 7.5-inch GP3000-series industrial HMI/operator interface terminal with TFT color display and DC24V power input.

Q2. What is the global part number?

The global code is:

PFXGP3400TAD

Q3. What software is used for programming?

The is supported by GP-Pro EX development software. The supported model des .

Can directly replace another GP3000 HMI?

Not always. Verify:

• Screen size
• Project compatibility
• Communication protocol
• Connector configuration
• Interface options

Different GP3000 variants may have different hardware configurations.

Q5. Ilus available?

Availability depends on supplier inventory because the series model has been discontinued. New surplus, unused stock, and refurbished units may still appear through industrial spare-part channels.

Q6. How should buyers verify authenticity?

Request:

• Actual unit photographs
• Model ing
• Global code PFXGP3400TAD
• Power-on test video or test report
• Touchscreen and communication verification

Q7. What warranty should buyers expect?

Warranty depends on the supplier. For discontinued industrial HMIs, warranty is usually provided by the seller rather than the original manufacturer. Confirm test procedures, return policy, and coverage before purchase.

Q8. What is the recommended replacement path?

For modernization projects, evaluate current Pro-face replacement models based on:

• Existing panel cutout
• PLC communication protocol
• GP-Pro EX project conversion
• Required communication interfaces
