Operator Interfaces for SBC's & Expandable Control Systems
eDisplay Models OP7200, OP7210
The OP7200 eDisplay is an intelligent operator interface that offers rugged I/O, built-in Ethernet connectivity, and optional A/D and touchscreen capabilities. The compact eDisplay is an ideal data acquisition and display device for OEM products and stand-alone systems such as factory floor controls. The unit's 10Base-T Ethernet facilitates remote diagnostics, control, and communication, including sending and receiving E-mails and alerts.
Two eDisplay models incorporate 24-27 digital I/O plus an I/O expansion port, 4 serial ports, the Rabbit 2000 microprocessor at 22.1 MHz, and 256K of Flash / 128K of SRAM (512K Flash/512K SRAM available). When front-panel mounted, the unit meets NEMA 4 water-resistance standards, making it suitable for use in harsh environments. The eDisplay's digital I/O include up to 19 protected inputs and 8 high-current sourcing or sinking outputs. The OP7200 model features 8 analog input channels configurable as 11-bit single-ended or four 12-bit differential. The OP7210 is a lower-cost version without A/D and touchscreen.
Both models come equipped with a 1/4 VGA display (320 x 240 pixels) with a 9-key keypad and programmable on/off white LED backlight. The OP7200 version also includes a 4096 x 4096 analog touchscreen. Both versions provide easy-to-use menu-building software and have a programmable audible alarm for prompt notification and keypad/display feedback.
The RS-232 ports can be configured as a single 5-wire port or as two 3-wire ports, while the 8 high-current outputs can be individually configured as sourcing, sinking, or tri-state via software. The analog inputs have 8 software-selectable gain voltage ranges from 0-1 V to 0-20 V. The eDisplay supports English and foreign language fonts, as well as graphic and bitmap images, and its C programmability offers design engineers unlimited flexibility. A font converter program is supplied, and different fonts, languages, and sizes can be used simultaneously in combination with graphic images.
Programming the eDisplay
Programs are developed for the OP7200 using Z-World's industry-proven Dynamic C software development system. An extensive library of drivers and demo programs is provided, along with royalty-free TCP/IP stack with source. Both OP7200 models can be programmed and debugged over Ethernet/Internet using appropriate accessory hardware. Demo programs include pop-up menuing, onscreen keypads, data transmission/reception over TCP/IP and serial, analog volt meter display, and many more.
The complete Tool Kit for the OP7200, p/n 101-0543, includes all the software and hardware tools needed to begin design, including Dynamic C development software and documentation on CD-ROM, user's manual with schematics, demonstration board, and serial cable for programming and debugging.
