The EH-OP10 model fulfills the need for a powerful yet cost effective operator interface system. The display is available with an eight line pixel based LCD. 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 keypad offers 47 programmable keys (24 with user LEDs). Slide-in legends make it easy to customize and document the operation of each key which has an LED. 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 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 256 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 program can be downloaded to any UniOP display through the serial line and permanently stored in Flash EPROM.

Graphic Capabilities

The EH-OP10 allows you to display bitmap graphics. These bitmap can be created with any Windows™ based software package capable of BMP format.

Keyboard Macro Editor

A feature that allows you to configure your UniOP Keys to do a variety of functions locally in the UniOP. For example: turning pages, setting attributes, setting LEDs, writing to the PLC, going to the alarm list, uploading a recipe set and many more.


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 16K 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 their type or manufacturer.
