The XL4 Series PLC Touch Screen automation controller, from Horner Automation, is considered "mature" and will soon no longer be in production. We recommend considering the new XL4 Prime, or additional 3.5" models: the XLE Series, the XLT Series, or the Horner Canvas 4.

Advanced High Speed Counter (>5000KHZ), Data Logging, WebOCS
The 2-channel High Speed Counter accepts frequencies exceeding 500kHz to support multiple modes for example: totalizing, quadrature, pulse measurement, frequency counting, and setpoint controlled outputs. With Horner WebMI, users can monitor as well as control plant data from the palm of the hand. Publishing directly from the OCS Controller, WebMI allows the monitoring or control of the same or unique web pages from a computer, tablet, etc. Completely within our free Cscape environment, WebMI allows for state-of-the-art HTML5 development without the need for web programming skills.
All of our Horner OCS automation control products can quickly and also easily configure for data logging. It only takes a few steps within Cscape to set up the data and frequency with which data can be logged to the on-board microSD card. Utilizing the data is just as simple, for example: files can send via email, text, or even transfer (.csv) via FTP.
