Description
Product Overview
The EZAutomation EZ-S6M-F is a programmable industrial Human-Machine Interface (HMI) from the EZTouch Enhanced 6-inch monochrome panel family. It provides operators with a graphical interface for monitoring PLC data, viewing machine conditions, and issuing control commands through a resistive touchscreen. The display uses a 5.7-inch STN monochrome LCD with 16 shades of gray and a 320 × 240 pixel resolution. A 32-bit Motorola ColdFire processor running at 40 MHz handles screen processing and communication tasks. The panel is designed for industrial control cabinets where a compact operator interface is required.
The EZ-S6M-F is the full-featured version of the EZTouch monochrome panel. It includes 512 KB of system RAM, with field-expandable memory options, and supports nonvolatile flash-card program backup. The communication architecture includes RS-232C, RS-422A, and RS-485A interfaces for connection to compatible PLC systems. Its standard driver support covers the EZTouch serial-driver library, while optional EZ Ethernet hardware provides additional network communication capability. The panel also supports up to 999 screens, subject to available application memory.
Designed for indoor industrial environments, the EZAutomation EZ-S6M-F uses a NEMA 4/4X-rated enclosure and a standard bezel. It operates from a 24 VDC supply within a documented 20–30 VDC range and consumes approximately 13 W. The model is now discontinued, so replacement planning should account for the original project file, PLC driver, serial wiring, screen dimensions, and mounting arrangement. EZAutomation identifies the EZ-T6C-F as its drop-in replacement, but the actual retrofit should still be checked against the installed panel and application.
Product Introduction
An HMI failure can interrupt operator access to machine status, alarms, recipes, and manual control functions. On an older installation, replacing the display is not always a simple hardware exchange. The original PLC driver, serial communication settings, application project, and cabinet cutout all affect whether a replacement can be commissioned without extensive changes.
The EZ-S6M-F is a full-featured monochrome EZTouch panel with serial PLC communication and expandable memory. Before ordering a replacement, confirm the panel revision, original application backup, communication cable, and optional Ethernet configuration.

EZ-S6M-F
Major Features and Advantages
5.7-inch monochrome touchscreen
The STN display provides 16 shades of gray at 320 × 240 resolution. This format supports conventional machine-status screens, alarm displays, operating menus, and numerical data presentation. Its monochrome design is suited to legacy control systems that do not require color graphics.
Full-featured memory architecture
The panel includes 512 KB of system RAM and supports optional memory expansion. Flash-card options provide nonvolatile storage for program backup and transfer. This is useful when maintaining older HMI installations, although the actual installed memory options should be inspected rather than inferred from the base model number.
Broad serial PLC communication
RS-232C, RS-422A, and RS-485A interfaces support connection to compatible PLC platforms. Driver selection and communication parameters must match the PLC program and installed communication hardware. A physically compatible serial connector does not guarantee protocol compatibility.
Optional Ethernet capability
The EZ- supports an optional EZ Ethernet card. This option should be verified on the physical unit because Ethernet functionality is not necessarily included in every standard configuration. Network integration also depends on the installed option hardware and application setup.
NEMA 4/4X enclosure
The panel’s NEMA 4/4X enclosure classification is intended for indoor industrial installations requiring protection against dust and water exposure under the applicable enclosure test conditions. It does not mean the panel is suitable for unrestricted outdoor exposure or immersion.
Programmable screen architecture
The EZTouch platform supports up to 999 screens, subject to available memory. Engineers can organize machine functions into operating pages, alarm screens, status displays, and maintenance menus using EZSeries programming software.
Legacy system maintenance
The model remains relevant to existing machines built around EZTouch hardware. Retaining the original unit can reduce the scope of an immediate retrofit, provided the touchscreen, backlight, communication ports, and application memory remain functional.

Frequently Asked Questions
Q1: What is the EZAutomation EZ- used for?
It is a programmable industrial HMI used to display PLC data and provide operator access to machine functions, status information, and alarm screens.
Q2: Does the EZ- have a color display?
No. It uses a 5.7-inch STN monochrome display with 16 shades of gray and 320 × 240 resolution.
Q3: What PLC communication interfaces does this panel support?
The panel supports RS-232C, RS-422A, and RS-485A serial communication. An optional EZ Ethernet card can provide additional network functionality. Confirm the installed option hardware and PLC driver before connection.
Q4: Can the EZ- be replaced by the EZ-T6C-F?
EZAutomation identifies the EZ-T6C-F as the drop-in replacement. However, confirm the cabinet cutout, mounting clips, power connection, PLC communication wiring, and application conversion requirements before carrying out the replacement.
Q5: Can I hot-swap the EZ-?
Do not assume hot-swap capability. Shut down the panel according to the machine’s electrical safety procedure, isolate the 24 VDC supply, and confirm whether the PLC and process can safely continue without operator-interface access.
Q6: Does the EZ- support firmware v3.1?
The panel’s software compatibility should be checked against the EZSeries programming software version and the original project file. A generic firmware v3.1 compatibility statement is not established by the model designation.
Q7: What should I check before purchasing a used EZ-?
Inspect the display for missing segments or uneven backlighting, test touchscreen response across the full active area, verify the serial communication ports, and check the memory and flash-card options. Request a power-on test and, where possible, confirmation that an application can be loaded and operated.
Procurement and Quality-Control Notes
The EZ- is a discontinued HMI. Replacement procurement should account for the condition of the display, touch surface, power supply circuitry, serial interfaces, and optional memory or Ethernet hardware.
Recommended inspection points:
- Verify the rear nameplate reads EZ-.
- Confirm the standard-bezel mechanical configuration.
- Inspect the LCD and touchscreen across the entire display area.
- Test RS-232C, RS-422A, and RS-485A communication as applicable.
- Confirm optional Ethernet hardware if required by the existing installation.
- Check RAM and flash-card configuration.
- Request evidence of successful power-on and application testing.
- Preserve the original HMI project file and PLC communication settings before replacement.
Procurement priority: Specify EZAutomation EZ-, 5.7-inch monochrome, 320 × 240, 24 VDC, full-featured serial HMI. Confirm the application backup and communication configuration before accepting a replacement.
