UniOP ePAD06-0046 Operator Interface

UniOP ePAD06-0046 Operator Interface Panel

The UniOP ePAD06-0046 is a ruggedized graphic operator panel engineered by Exor for local plant and machinery monitoring, auxiliary marine switchboards, and compact industrial automation skids. Equipped with a high-contrast 120 × 32 pixel monochrome LCD, a customized tactile keypad matrix, and native multi-protocol serial connectivity, the ePAD06-0046 delivers dependable human-machine interaction in demanding operating environments.

Unlike commercial touchscreens susceptible to false triggers or moisture failure, the ePAD06 relies on an industrial membrane keypad featuring tactile feedback switches, dedicated navigation keys, and configurable function buttons with slide-in legend strips. Designed to operate from an isolated nominal 24 VDC bus, the terminal is sealed to an IP65 ingress rating on the front bezel, making it resilient against spray, dust, and continuous industrial vibrations.

Frequently Asked Questions

What is the primary difference between the ePAD06-0046 and the ePAD05-0046?

The ePAD05 features an internal battery-backed hardware Real-Time Clock (RTC), 16 KB recipe storage, and dual-driver concurrent communication. The ePAD06-0046 is a streamlined, cost-effective model designed for direct PLC control and monitoring without native internal RTC or recipe memory.

Can I replace an older ePAD04-0046 unit directly with an ePAD06-0046?

Yes. The mechanical panel cutout (136 mm × 96 mm), front bezel size (149 mm × 109 mm), and DB15 communication port pin assignments are identical, making the ePAD06-0046 a drop-in physical replacement for older legacy units.

Which software is used to program and upload projects to the ePAD06-0046?

The unit is configured using UniOP Designer software (Version 5 or Version 6). You can download project files via an RS-232 serial programming cable connected to the main DB15 port using a matching UniOP serial adapter cable (CA114 / CA232).

Does the ePAD06-0046 have a touchscreen?

No. The ePAD06 is specifically engineered with an industrial tactile membrane keyboard rather than a touchscreen. This mechanical button design provides positive tactile feedback and ensures error-free operation when working with gloves or in environments where grease, spray, and moisture make touchscreens unreliable.

What is the proper procedure if the display has power but won’t communicate with the PLC?

First, verify that the pin assignment matches the communication protocol (RS-232 vs. RS-422/RS-485). Second, confirm that the communication speed, parity, station address, and node numbering configured in UniOP Designer match the PLC’s hardware configuration exactly. Finally, check that the DC 0V common rail is bonded properly to prevent floating ground offsets on the communication lines.
