Overview Manuals LCD Operation Host Link Setup Peripheral Data Product Applications

Features:

  • LCD operator display with keypad-controlled viewing adjustments
  • 40K application configuration with real-time clock functions
  • Separate controller-communication and RS-232 peripheral paths
The LCD prefix and P1 suffix are the fastest way to separate 2707-L40P1 from the VFD and high-voltage catalogs that share the DTAM Plus enclosure family.

Its 40K identity signals an application-oriented station rather than a display-only component, so the retained project is part of the product decision.

After catalog identity is established, host communication and peripheral handling remain separate engineering decisions and should not be inferred from the common front-panel appearance.
Apter Power can coordinate official-document review, quotation, and sourcing support for 2707-L40P1.

  • Display format: Four rows keep process values, prompts, and operator choices together at the machine.
  • Local adjustment: Keypad-controlled backlight and contrast let commissioning staff tune visibility without editing the application.
  • Thermal boundary: The LCD-specific ambient limit must guide enclosure ventilation and hot-panel acceptance.
  • Configurable interface: The controller port can use the documented RS-232C or RS-485 electrical path.
  • Protocol alignment: DH-485 or DF1 selection must agree with the host, application, and switch record.
  • Cable control: The runtime cable must match the chosen controller interface rather than only fitting the connector.
  • Dedicated channel: The 40K catalog provides an RS-232C printer port separate from host communication.
  • Clocked output: The real-time clock supports application-defined time stamps for printed information.
  • ASCII entry: Supported decoded data can enter through the peripheral path when the application maps it deliberately.
  • Controller data access: Monitor and manipulate PLC or SLC process values from a local operator station.
  • Recipe and point work: Change approved data blocks or reach configured points during production and setup.
  • Peripheral-assisted operation: Produce time-referenced reports or accept application-defined decoded ASCII data.
Description
For a local station that requires an LCD rather than a vacuum fluorescent display, 2707-L40P1 is the 40K Allen-Bradley DTAM Plus catalog with the low-voltage P1 identity. That combination distinguishes the terminal from visually similar VFD and P2 configurations before any application file is considered.

At the machine, an application stored in 2707-L40P1 turns controller data into operator prompts, entries, and production-facing information. The terminal therefore belongs to both the control-system communication path and the documented operating procedure, not merely to the panel cutout.

A maintainable replacement record should connect 2707-L40P1 to the exact application and installed interface design. Keeping that relationship intact helps procurement and engineering avoid selecting a mechanically similar DTAM Plus catalog whose display or supply configuration changes the retrofit.

Technical notes
Before energizing 2707-L40P1, read the complete catalog label and confirm that the panel follows the P1 electrical design. Rockwell Automation permits 15–23 VAC or 20–30 VDC and specifies a Class 2 source for P1 units; stop the retrofit if the existing circuit was built for a P2 terminal.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why might 2707-L40P1 show the restored screens yet remain offline after an application recovery?
Treat the application, protocol choice, switch positions, host address, and runtime cable as one communication chain. Compare each item with the machine backup before replacing the terminal or controller port.
If text on 2707-L40P1 fades after the enclosure warms, what should maintenance check before replacing the display?
Measure the air around the terminal, inspect panel ventilation, and retest the keypad backlight and contrast controls. Replace the display only after the LCD environment and supply remain within the documented limits.
Can a barcode reader send useful production data to 2707-L40P1 without changes to the saved application?
Not by connection alone. The reader must use the supported peripheral path, and the 40K application must define the ASCII format, destination value, and validation expected from the decoded data.
When report time stamps from 2707-L40P1 are wrong, where should troubleshooting begin?
Compare the terminal clock with the approved machine time, then review the report screen and printer-port assignment. Correct the clock or application source before changing the controller program.
What should a buyer request with 2707-L40P1 so a removed station can be commissioned again?
Request the readable catalog label, current application file, host protocol and address, switch record, runtime cable catalog, printer-port use, and panel power drawing. Keep them together as the recovery package.
After panel rewiring, when should power-up of 2707-L40P1 be stopped?
Stop if the complete label confirms a P1 unit but the source class, AC or DC range, polarity where applicable, or protective arrangement cannot be verified. Resolve the drawing and field circuit before energizing.
