UniOP eTOP05

The UniOP eTOP05 is a classic industrial HMI (Human Machine Interface) from the eTOP series, manufactured by Exor. It was widely used throughout the 2000s and 2010s as a compact, reliable interface for PLCs in various manufacturing environments.

While it is now considered a legacy product, its robust hardware means thousands are still in active service today.

1. Key Technical Specifications

The eTOP05 is a 5.6-inch monochrome display, optimized for text-heavy interfaces and basic machine control.

2. Communication and Connectivity

The eTOP05 is highly versatile due to its support for a massive library of PLC protocols. It features a modular communication approach:

• PC/Printer Port: A 15-pin D-Sub connector used for programming the unit or connecting a serial printer.

• PLC Port: Supports RS-232, RS-422, RS-485, and 20mA Current Loop.

• Optional Modules: The rear of the unit has a slot for TCM (Technical Communication Modules) to allow for Ethernet, Profibus, CANopen, or DeviceNet connectivity.

3. Programming Software: JMobile vs. Designer

The eTOP05 is primarily programmed using Designer 6 (often referred to as UniOP Designer).

• Legacy Support: It does not support the modern JMobile software used by newer Exor/UniOP panels.

• Protocol Library: One of the strengths of Designer 6 is its ability to communicate with almost any PLC (Allen-Bradley, Siemens, Omron, Mitsubishi, Modbus, etc.) using dedicated drivers.

4. Common Maintenance Issues

As these units age, two specific hardware components are likely to fail:

• The Backlight (CCFL): If the screen is powered but remains dark (you can see faint text if you shine a flashlight on the glass), the CCFL bulb or the high-voltage inverter has failed.

• The Touch Overlay: If the screen responds in the wrong place or not at all, the resistive overlay may be “pitted” or worn. You can attempt a recalibration through the system menu.

• The Internal Battery: There is a small lithium battery inside used to maintain the Real-Time Clock (RTC). If the HMI loses its date/time settings after a power cycle, the battery needs replacement.

5. Accessing the System Menu

To configure the IP address or perform a touch calibration, you must enter the Internal Setup Mode:

1. Power off the unit.

2. Power on while touching the screen (typically the top-left corner, though this varies by firmware).

3. The “System Menu” will appear, allowing you to change communication parameters or clear the project memory.
