Eaton DPM-MC2 PROFIBUS DP Master Module - Dedicated Communication Card for MICRO PANEL MC2 Series

Meta Description

Original Eaton DPM-MC2 PROFIBUS DP master communication module complying with EN50170 standard, exclusively for MICRO PANEL MC2 touch panels, equipped with diagnostic LED indicators, isolated 9-pin DSub PROFIBUS port, CE & UL certified for factory automation networking.

1. Product Overview

The Eaton DPM-MC2 is a dedicated plug-in PROFIBUS DP master communication expansion module tailor-made for Eaton MICRO PANEL MC2 integrated HMI/PLC units. Built in accordance with the international EN50170 PROFIBUS standard, this module empowers MICRO PANEL MC2 panels to act as a PROFIBUS DP network master, enabling seamless cyclic data exchange with all PROFIBUS DP slave devices, including remote I/O modules, variable frequency drives, servo controllers, motor protection relays, and field sensors.
Installed via the dedicated internal expansion slot of MICRO PANEL MC2, DPM-MC2 delivers reliable high-speed industrial bus communication without additional external gateways. Four front-mounted diagnostic LEDs provide real-time visual feedback of hardware status, bus running state, communication faults, and token transmission, drastically simplifying on-site commissioning and troubleshooting.
Key installation reminder: The DPM-MC2 module must only be inserted or removed when the MICRO PANEL MC2 host unit is fully de-energized to avoid hardware damage and communication failure. Eaton. This module is solely compatible with MICRO PANEL MC2 series panels and cannot be used with other Eaton HMI/PLC platforms.

2. Core Key Features

2.1 Standard PROFIBUS DP Master Functionality

  • Full compliance with EN50170 PROFIBUS specification, operates as bus master to scan and manage all DP slave nodes on the network.

  • Supports standard PROFIBUS wiring topology with built-in bus termination power supply pins on the DSub connector

  • Real-time bidirectional data transmission between MICRO PANEL MC2 and field bus slaves for process visualization and logic control

2.2 Intuitive 4-LED Diagnostic Indicator Panel

Four status LEDs on the module front cover enable instant fault judgment without software diagnosis:

  1. READY (Yellow)


    • Steady ON: Communication interface initialized and ready

    • Cyclic flashing: Bootloader running during startup

    • Irregular flashing: Hardware or system abnormal error

    • OFF: Severe hardware fault

  3. RUN (Green)


    • Steady ON: PROFIBUS bus communication running normally

    • Cyclic flashing: Bus communication suspended

    • Irregular flashing: Missing or incorrect bus configuration

    • OFF: No PROFIBUS bus connection detected

  5. ERROR (Red)


    • Steady ON: PROFIBUS bus communication error occurred

    • OFF: Bus operating without faults

  7. STATUS (Yellow)


    • Steady ON: Module transmitting data or holding bus token

    • OFF: No token access to the PROFIBUS bus
