Product Details

Modicon MM-PMA1-30S is a legacy panelmate plus hmi panel and reliable operator interface terminal within the Modicon PanelMate Plus family, alternate part number 92-00807-02. This legacy modicon display panel is designed for cabinet cutout installation, serving as the on-site human-machine interface for Modicon 984 PLC systems. It communicates via Modbus serial protocol to retrieve real-time process data, equipment running status, alarm messages and setpoint values. Operators can send manual start-stop commands, adjust control setpoints and acknowledge active alarms directly through the integrated keypad and display. Built for continuous operation in factory environments, it supports custom screen configuration, trend viewing, alarm queue management and simple recipe storage for batch production. The heavy-duty metal housing provides resistance against vibration and dust, and the built-in power supply accepts wide-range AC mains input. As a discontinued legacy spare, this panelmate plus hmi panel acts as a drop-in replacement to restore local operator monitoring and control for ageing Modicon automation installations.

Supported Functions

This panelmate plus hmi panel fetches real-time register data from the connected Modicon PLC and visualizes process variables, equipment status and running trends on screen. The operator interface terminal allows operators to submit control commands, modify setpoints and confirm alarms back to the host controller. This legacy modicon display panel supports custom graphic pages, dynamic data refresh, alarm logging and recipe recall for repeated production batches. It runs built-in self-diagnostics to detect serial communication loss, internal memory fault and power abnormality, and outputs fault prompts to guide maintenance work. It can work together with Modicon 984 CPUs and distributed remote I/O racks to complete local monitoring and sequence control.

Core Functions

As a dedicated operator interface terminal, this panelmate plus hmi panel builds the interactive bridge between field operators and PLC control logic. It converts raw PLC register data into readable visual information and translates keypad operations into valid control instructions. This legacy modicon display panel works as a direct spare to rebuild stable local human-machine supervision for ageing Modicon automation racks.
