XLW Prime Series, HMI / PLC Controller

XLW Prime Series, HMI / PLC Controller


The XLW Prime sets the standard for functionality and performance. The XL Prime Series of HMI Automation Controllers offers performance upgrades and a highly secure, modern memory architecture. This is accomplished with a new Horner designed System on Module (SOM) – containing a faster CPU, onboard mass storage and 100% non-volatile memory. The only battery is a small coin cell – simply tasked with maintaining the clock.

Automation Control with Easy Integration

If you are a new automation designer looking for an innovative, reliable control solution – the XL Prime Series offers a fully integrated product in hardware and software. If you are an existing XL Series user – your current application program will port straight through in less than 30 seconds. All units feature a built-in logic engine, operator interface, networking, and expandable I/O.

Horner App Enabled
The Horner App is the first automation app to give customers the ability to access all WebOCS enabled controllers with their iOS or Android phone or tablet.


The XL Prime Series features all-in-one control and performs all machine functions in a unified hardware design: Logic Control, Operator Interface, I/O, and Networking. These HMI controllers are designed with a modern memory architecture based on a custom designed SOM (System on Module) utilizing a powerful ARM microprocessor and 100% non-volatile memory for reliability. With high-performance logic engines, the XLW Prime automation controller offers fast scan times, solving user logic using Variable-based Advanced Ladder logic or the IEC 6-1131 language set.

Online Programming and Remote Control

Online programming is made available through WebMI, MQTT, and the Horner App, which also allows for remote control and enables users to make logic changes without stopping the controller. Communication is based on Ethernet IP, Modbus TCP, BACnet IP, FTP file transfer, or email. Collected data can be logged including record machine and process variables, which can be saved to a microSD or USB Flash Drive.


Fast Processing and Response Time

The screen is a high-resolution color touchscreen that is capable of displaying detailed graphics and nearly instantaneous screen updates. The XL Prime Series of automation controllers also includes an advanced high-speed counter with four built-in counters supporting frequencies over 500 kHz.

Advanced Features of XLW Prime Series Automation Controllers

Logic engine features 1MB of application memory with a 0.02mS/K logic scan. Online Programming Mode (making logic changes on the fly without going thru stop mode) is supported. Operator Interface features include:

  • 800×480 LCD TFT color graphics display with a high resolution resistive touchscreen
  • USB 2.0 On-the-Go port (mini-B 5pin) is available for programming
  • USB 2.0 Host port (A) is available for exchanging files with USB FLASH drives
  • Two (2) RS-232 and one (1) RS-485 port support RTU / Modbus Commander / Responder (Master / Slave), ASCII In/Out, and PLC / Drive downloadable protocols

Networking Features for XLW Prime Series Automation Controllers

  • Built-in 10/100 Ethernet port
  • Integrated CsCAN port

All units feature a microSD slot, supporting at least 32GB.
