The QX Series is a Powerful All-in-One Controller with Vibrant Color Graphics, Embedded Ethernet, and Snap-on I/O

The QX Color-Touch OCS series features a fast, powerful logic engine, XGA and SVGA resolution touch screens and optional snap-on I/O. OCS (Operator Control Station) is a robust, reliable control product that combines a traditional controller… programmed in ladder logic...operator interface, I/O and networking into an integrated, all-in-one unit using a single software package. The QX has four screen sizes (8.4", 10.4", 12.1", and 15"), and a typical logic scan rate of 0.2mS/K. In addition, the QX has embedded Ethernet and supports many Internet capabilities such as remote data access, programming, hosting HTML-based Web pages, and FTP sites. Plus, the QX line has a built-in CompactFLASH® slot that allows users to easily store machine or process data (up to 2GB). Programs can be updated and loaded through CompactFLASH, a real advantage for OEMs or those supporting distant sites.

The QX Color-Touch OCS has optional I/O and video add-on features too. Base QX units provide control, operator interface, and communication functionality while the optional QX Backpack (BP) units provide I/O connectivity. Video connectivity can be achieved with the VIM400, (QX 751 will use VIM401, available Spring/Summer of 2009) the video input option. This modularity allows the I/O or video functions to be omitted or added to more precisely meet the application requirements.

Backpack Options Add Local and Remote I/O
There are two Backpack options for the QX (HE-BP41 & HE-BP43, with high speed counter). Both are compact and easy-to-install on the back of the QX base unit. With Backpack HE-BP41 installed, up to two SmartStack I/O modules can be snapped on. (HE-BP43 supports four.)In addition, Backpack users can connect hundreds of local or remote I/O using our Fiber Optic (FOX) Expansion I/O and our SmartStix terminal-type I/O modules. If the HE-BP43 Backpack is selected, a 500 KHz High Speed Counter (with PWM) is included. For smaller applications, the QX with Backpack creates a single, compact package that includes control, display, networking, and up to four snap-on SmartStack I/O modules.

Video Input Option Allows Machine Viewing and More Security
The advanced feature of video input functionality (VIM400) for the QX Color-Touch OCS is being used more and more by companies who need to integrate security, view machinery in remote locations, or need to incorporate a machine vision monitor with their control system.The video input option allows four channels of NTSC or PAL video to be connected to the QX (QX451, QX551, QX651. (The new QX751 will use VIM401 available Spring/Summer 2009) to provide video viewing and capture capability. Users can view video with the full frame rate at VGA resolution. Video can also be viewed freeze frame, and/or saved as a single frame to CompactFLASH. A separate control register allows the controller to automatically freeze or save video snap-shots based on the machine state.
