Display and User Interface

The Schneider MMPMF2300 features a 5.7-inch monochrome LCD with 320 × 240 resolution. A resistive touchscreen registers input even when you wear gloves. Sixteen programmable function keys provide one-touch access to critical controls. Ten numeric keys allow fast data entry without opening the touchscreen keyboard.

Communication Connectivity

Two RS-232 ports support serial connections to PLCs, drives, or printers. A third port supports RS-422 or RS-485 for multi-drop industrial networks. This interface speaks Modbus RTU, Modbus TCP, Uni-TE, and Modbus Plus protocols. Consequently, you can connect to most Schneider and third-party controllers directly.

Memory and Data Storage

The unit provides 2 MB of Flash memory for storing application screens and logic. An additional 512 KB of SRAM holds runtime variables and alarm logs. A lithium battery preserves SRAM contents and maintains the real-time clock. This battery lasts approximately 5 years under normal operating conditions.

Installation and Mounting

Mount this interface into a standard panel cutout of 197 mm × 142 mm. The front panel meets IP65 rating when you properly seal the gasket. You can use the four corner clips for tool-less mounting in thin panels. For best results, install the unit away from direct sunlight or heat sources.

Programming and Configuration

You need Schneider Vijeo Designer software to create applications for this terminal. The software supports bitmap images, vector graphics, and multi-language text. You can download applications through either serial port or a CompactFlash card. Therefore, you do not need a PC at the machine location for updates.

Visual Indicators and Alarms

The interface displays real-time alarms with time-stamping from the internal RTC. A blinking LED indicates communication activity with the connected PLC. The backlight dims automatically after a user-defined period of inactivity. Consequently, you extend the CCFL backlight life beyond its 40,000-hour rating.

Why Choose This Interface

This hybrid unit gives operators both keypad and touchscreen input options. It works perfectly for environments where gloves make touch-only screens difficult. Therefore, manufacturers choose this interface for packaging lines, food processing, and heavy machinery.
