Horner OCS PLCs

Horner Micro OCS Series

Compact All-in-One PLC, HMI and I/O Control

The **Horner Micro OCS Series** is a range of compact, cost-effective **all-in-one industrial controllers** combining a powerful PLC, colour touchscreen HMI, built-in I/O and industrial communications in a single unit. Available with **4-inch, 7-inch and 10-inch colour touchscreen displays**, the Micro OCS Series provides a complete automation solution for machine control, pumping systems, HVAC, water treatment, food processing, packaging, OEM equipment and a wide variety of industrial applications. By integrating the **PLC, HMI, I/O and communications** into one compact controller, the Horner Micro OCS can significantly reduce panel space, wiring, installation time and overall system cost compared with traditional systems using separate PLCs, operator panels and I/O modules.

Micro OCS – X4, X7 and X10

The Micro OCS range is available in three touchscreen sizes:

X4** – 4.3-inch colour touchscreen, 480 × 272 resolution
X7** – 7-inch colour touchscreen, 800 × 480 resolution
X10** – 10.1-inch colour touchscreen, 1024 × 600 resolution

All three models use the same basic control platform, making it easy to select the display size best suited to the application while maintaining a common programming environment.

PLC + HMI + I/O in One Controller

At the heart of every Micro OCS is an integrated logic controller capable of handling demanding machine and process control applications. Instead of installing and programming separate PLC and HMI components, the Micro OCS provides the control logic and operator interface within the same unit.

This integrated architecture simplifies system design and provides important benefits including:

Reduced control panel space
Less wiring between components
Fewer individual components
Faster installation
Simplified programming
Easier commissioning
Reduced system cost
Simplified maintenance and troubleshooting

Built-In Digital and Analogue I/O

One of the major advantages of the Micro OCS Series is its comprehensive **built-in I/O**. Standard configurations provide up to **30 integrated I/O points**, including digital inputs and outputs, high-speed I/O and analogue inputs and outputs. Two principal I/O configurations are available.

Model A – Digital Output Version

The Model A configuration provides:

12 digital inputs
12 digital outputs
4 high-speed inputs included within the digital inputs
2 high-speed outputs included within the digital outputs
4 analogue inputs
2 analogue outputs

Model R – Relay Output Version

For applications requiring relay switching, Model R provides:

12 digital inputs
2 digital outputs
6 relay outputs
4 high-speed inputs
2 high-speed outputs
4 analogue inputs
2 analogue outputs

This combination of digital, high-speed and analogue I/O makes the Micro OCS suitable for many machines and control systems without requiring additional I/O modules.

Expandable I/O

Where the built-in I/O is not sufficient, the Micro OCS can be expanded using Horner remote and distributed I/O solutions. Expansion can be achieved through **CAN, Ethernet and serial communications**, depending on the required architecture and I/O system. This allows a Micro OCS to begin as a compact standalone controller and expand as the requirements of the machine or process increase.

Powerful Control Capability

Despite its compact size and competitive price, the Micro OCS provides the processing capability required for a wide variety of industrial control applications.

Features include:

Fast PLC logic execution
Floating-point mathematics
PID process control
AutoTune PID capability
High-speed inputs and outputs
Data logging
Alarm handling
Recipe management
Trending
microSD removable memory
Local program comments
Real-time monitoring and diagnostics

The X4, X7 and X10 provide fast logic execution of approximately **0.4 ms per K of logic**, making the Micro Series suitable for applications requiring responsive machine and process control.

High-Speed I/O

The Micro OCS includes **high-speed I/O** as part of its standard onboard I/O configuration.

High-speed inputs can operate at frequencies up to 500 kHz, allowing the controller to interface with devices such as:

Encoders
Proximity sensors
High-speed counters
Flow meters
Pulse-output instruments
Position sensors

High-speed outputs can also be used for applications requiring accurate pulse control.

Integrated Colour Touchscreen HMI

The X4, X7 and X10 feature bright colour touchscreen displays, allowing the controller to provide a complete local operator interface without requiring a separate HMI.

Applications can incorporate graphical objects including:

Pushbuttons
Selector switches
Numeric displays
Data entry
Status indicators
Gauges
Alarm screens
Trends
Graphs
Recipes
Machine status displays
Process diagrams
Navigation screens

Up to **250 display pages** can be configured, providing considerable flexibility when developing operator interfaces for more sophisticated machines and processes.

Extensive Communications

The Micro OCS provides a wide range of communications options for connection to variable speed drives, soft starters, instrumentation, remote I/O, PLCs, SCADA systems and other industrial equipment.

Depending on configuration and software options, supported communications include:

Ethernet
Modbus TCP
Modbus RTU
EtherNet/IP
BACnet/IP
BACnet MS/TP
RS-232
RS-485
CAN
CsCAN
CANopen
SAE J1939
FTP
SMTP
MQTT

This extensive communications capability allows the Micro OCS to operate as both a machine controller and an important communications gateway within an automation system.

Ethernet Connectivity

Ethernet connectivity on the X4, X7 and X10 allows the Micro OCS to communicate with other automation equipment and plant networks.

Applications can include communications with:

Variable Frequency Drives
Soft Starters
Remote I/O
PLCs
SCADA systems
Building Management Systems
Energy meters
Instrumentation
Other Horner OCS controllers

Support for protocols such as **Modbus TCP and EtherNet/IP** makes integration with third-party automation equipment straightforward.

Remote Access and WebMI

The Micro OCS supports Horner's remote connectivity technologies, including **WebMI**.

WebMI allows authorised users to access OCS information through an HTML5-compatible web browser. This makes it possible to remotely view machine or process information from devices such as:

Desktop computers
Laptops
Tablets
Smartphones

Remote access can provide maintenance personnel, operators and system managers with valuable visibility of equipment without requiring them to be physically located at the machine. The latest Micro OCS firmware also supports integration with **Horner OCS360**, providing additional options for remote connectivity and management.

Programmed with Horner Cscape

The entire Micro OCS application is developed using **Horner Cscape programming software**.

Cscape provides a single integrated development environment for:

PLC programming
HMI screen development
I/O configuration
Network configuration
Communications setup
Data logging
Alarm configuration
Recipe development
System diagnostics

Rather than using separate software packages for the PLC and HMI, the complete Micro OCS application can be developed and maintained within a single Cscape project. Cscape supports Horner's powerful Advanced Ladder programming as well as IEC 61131 programming languages, providing the flexibility required for both straightforward and sophisticated automation applications.

Compact Panel Design

The Micro OCS Series has been specifically designed to provide maximum functionality in a compact package. Its slim construction reduces the amount of space required inside the control panel while the integrated architecture eliminates many of the separate components normally required in a PLC-based control system. This makes the Micro OCS particularly attractive for **OEM machine builders and compact control panels** where both panel space and overall system cost are important.

Typical Micro OCS Applications

The combination of PLC, touchscreen HMI, integrated I/O and industrial communications makes the Micro OCS suitable for applications including:

Pump control systems
Irrigation systems
Water and wastewater treatment
HVAC and environmental control
Packaging machinery
Food and beverage processing
