The Micro OCS Series, from Horner Automation, is considered "mature" and will soon no longer be in production. We recommend considering the newest 4" models, the XL4 Prime and the Horner Canvas 4, or additional models such as the XLE Series and XLT Series.
X4 Integrated Automation Controller with Touchscreen HMI
With fully integrated hardware and software, the Micro OCS Series offers easy programming, installation, development, as well as easy set-up. The X4 Micro OCS automation controller has a small footprint and can also easily retrofit into an existing system with little effort. Many variations of distributed remote I/O, including OCS-I/O, SmartBlock, SmartStix, and SmartMod can be connected via CsCAN, Ethernet, in addition to Modbus. RTU/Modbus based SmartMod I/O is also a cost-effective means of adding a small amount of analog I/O. Furthermore, the X4 touchscreen HMI controller utilizes MicroSD Data Storage Memory, ideal for data logging, machine recipes, and application files.
- display of complex graphical objects including trends, gauges, meters, as well as animations
- advanced control capabilities including floating point, multiple auto-tuning PID loops, and also string handling capabilities
- intuitive interface
- removable media for storage of programs, data logging, or screen captures
- CsCAN networking port for communication with remote I/O, other controllers, or PCs
- Cscape programming software that allows all aspects of the X4 touchscreen HMI controller to be programmed and configured from one integrated application
- fail-safe system allows an application to continue running in the event of soft failures such as battery power loss or battery backed register RAM / application flash corruption
- clone function allows the user to "clone" the OCS, which copies the application program and unit settings stored in battery backed RAM, and allows it to be transferred to a different OCS (must be the exact same model)
Comprehensive Embedded Remote and I/O Options
The Micro OCS Series is designed as a modular system for easy selection and growth; CsCAN (CAN Based) high speed networking and Modbus RTU networking capabilities are standard in both A and R model controllers. Furthermore, remote I/O options offer high performance, accurate analog, and also easy-to-configure digital only modules. Horner I/O has flexible communication options that easily expand current systems.
Slim Design, Versatile Function on the X4 Touchscreen HMI Controller
The small, sleek profile of the X4 enables users to fit more in a panel, saving space, and resources. The X4 packs a big picture into an overall small package. With just a 4.6 x 3.5" cutout, this 4.3" wide aspect screen is very friendly, intuitive, and clear. With the addition of the X4 OCS controller, our engineers at Horner Automation offer a slim, versatile, as well as complimentary product to our existing line of robust industrial solutions. Moreover, the X4 as an introductory piece empowers your organization to grow by seamlessly incorporating additional Horner solutions (such as our more basic X2 controller or new, premium X5 Prime OCS controllers) to your expanding system.
Free HMI Programming Software Included
The Micro OCS Series (developed using a single, industry-recognized software platform, Cscape) combines graphical ladder logic programming, operator interface development, I/O configuration, as well as network configuration. The user-friendly interface provides free form and drag & drop editor, as well as more than 100 functions to choose from. In addition to the Cscape Advanced Ladder offering, Cscape also supports the IEC 1131 programming languages.
Common Uses of the X4 Micro OCS Touchscreen HMI Controller
In the market of fixed I/O, web-compatible controllers, the X4 touchscreen HMI controller is unmatched. Suitable for most applications across a diverse range of industries, the X4 exceeds standards and expectations. With powerful processor speeds, an intuitive user interface, and also rugged durability, the suite of capabilities within the X4 are similar to our new XL Prime line of products. With proven success across a wide variety of applications, the Micro OCS series is ideal for:
- power management and back-up generation
- packaging machinery
- compressor control
- pump control
- food and beverage processing
- motion control
- distributed conveyor control
- HVAC / environmental control
- mobile machinery
- manufacturing
- automotive parts
