16 Line x 40 Character LCD
Full-Graphic 320x240 Pixel Resolution
Graphics capable

The EH-OP30 fulfills the need for a powerful yet cost effective operator interface system. Displays are sixteen lines of a pixel based LCD in passive 16 color. These pixel addressable displays allow graphic capabilities with our Designer for Windows software package. Each line can contain up to 40 characters. Each page can contain up to 32 lines. These lines can be accessed by scrolling with the arrow keys. Brightness control is provided to adjust the display for easy viewing under nearly any condition.

Display Variables

PLC internal variables can be shown on any of the many display pages. The number of variables that can be viewed at one time is limited only by the display size. UniOP also provides scaling (linear conversion) of the displayed data. The final value can then be shown in several useful formats including barograph, date, time, decimal, bit, hexadecimal, floating point, and string. Data entry with valid range verification is also available for each data type.

Data Entry

The integral ASCII keypad offers 56 programmable keys and 24 user-definable LEDs. UniOP also features an internal battery-backed real time clock. Time and date information from the clock are periodically updated in the PLC to enable processing based on time-of-day, day-of-week or any other period.


UniOP can monitor and display up to 1024 alarms. Attributes and unique messages for each alarm can be defined. Operator acknowledgment can also be required. The last 1024 alarm events detected by the UniOP are retained in an internal event list. This list can be viewed on screen or printed on a serial printer to obtain a permanent record.


An eight-level password protection scheme protects critical system features from undesired access.


Custom display screens are developed using the UniOP Designer™ for Windows™ programming software. Your completed project file can be downloaded to the display through the serial port and permanently stored on a SSFDC memory card.

Graphic Capabilities

The EH-OP30 allows you to display bitmap graphics. These bitmap graphics can be created with any Windows™ based software package capable of BMP format.

Keyboard Macro Editor

A feature allowing you to configure your keys to do a variety of functions locally in the UniOP. For example: turning pages, setting attributes, setting LEDs, writing to PLC, going to alarm list, uploading or downloading a recipe set and many more. This can save many hours of ladder logic programming.


This feature allows you to create a recipe with up to 255 parameter sets for each page of the project file. UniOP has a total of 32K reserved for recipe storage. You can upload or download a parameter set from or to the PLC. Once a parameter set has been downloaded to the PLC, the data contained within the parameter set can be modified.

UniNET Network

The UniNET network allows the user to design a network in many different ways for use of several UniOP panels with several PLCs. This way data can be written to or retrieved from the PLCs in many different locations at one time. The UniNET network creates a bridge between UniOP panels which allows data to be shared by all PLCs in the network, regardless of the type or manufacturer.
