emPC-A/RPI3 Embedded Computing System Raspberry Pi 3 Module
Manufacturer: Janz Tec AG
The emPC-A/RPI3 Industrial Controller based on the ubiquitous Raspberry Pi 3. It includes many extra features that expand the usefulness of the Raspberry Pi computer for industrial applications, such as a CANbus interface. An enhanced version of the tried-and-tested emPC-A/RPI2, the emPC-A/RPI3 has been designed especially for automation and control applications. The new system not only delivers enhanced performance, it also has Bluetooth and Wi-Fi interfaces for mobile communication that can be used to create networks for mobile machines. Raspbian Jessie Light is the recommended operating system, and, like the previous model, the new version also offers CODESYS control software compatibility as well as CANbus and other communication features.
The Raspberry Pi embedded computer has shown that it is suited to industrial demands when fitted with the additional customized Janz power supply and I/O resources. The Janz additions provide a 24V power supply, an optically-isolated CAN interface, a real-time clock, digital I/O, and an additional RS232/RS485 interface. The device is supplied in a robust, lightweight (1lb) EMI-proof plastic housing (4” x 3.8” x 1.2”) that is suitable for desktop, wall, or DINrail mounting.
The fanless emPC-A/RPI3 is powered by a quad-core 1.2GHz ARM Cortex-A53 CPU, with 1GB DDR2 RAM system memory, and an externally-accessible microSD card slot for holding the operating system and driver software. The input power supply required is 9-32VDC , and the interfaces provided include: 10/100Mbit/s Ethernet, WiFi/WLAN, Bluetooth Low Energy (BLE), HDMI graphic interface, 4 x USB2.0, RS232, CANbus, RS232 (Rx, Tx, RTS, CTS) switchable to RS485, 4 x digital inputs (24VDC), 4 x digital outputs (24VDC).
Note: The emPC-A/RPI3 can be ordered in several versions but a microSD card is always necessary to run the device. This fits in the SD card slot on the internal Raspberry module. The emPC-A/RPI3 comes ready to install the Raspbian operating system. Customers can provide their own microSD card and download and install standard Raspian image themselves from https://www.raspberrypi.org/downloads/ (Raspbian Jessie Lite, or Raspbian Jessie recommended; NOOBS installation is not supported). They can also download Janz Tec’s additional device drivers free of charge from our website on the product page. A second option is to order the system with the microSD card that has the OS and device drivers pre-installed. If the additional interfaces of the emPC-A/RPI (RTC, CAN, RS232/RS485) are required, then the Janz Tec emPC-A/RPI Linux driver package on SD card should be purchased (SD-MIC-008GB 8 GB microSD card plus SO-IMG-00001 Operating System Image.) This SD card contains a ready-to-use Raspbian JESSIE light operating system image with pre-installed Linux device drivers for available interfaces and I/Os. This Raspbian-compatible .deb package enables the additional features of the emPC-A/RPI such as RTC, CAN, and RS232/RS485. Other options include a compatible power supply, a Java environment, and a CODESYS SoftPLC runtime environment.
For use in a CODESYS environment, a Java virtual machine (SO-JVM-EMB01), and a CODESYS V3 Control License (part no. SO-CDS-SL001 ) can be preinstalled on the SD card. CAN/CANopen tools are also available (SO-SOF-XXXXX). CODESYS is a soft PLC program created by 3S-Smart Software Solutions GmbH. This IEC 61131-3 programming system in combination with the emPC-A/RPI system is ideal for test, industrial, and educational applications since the controller can make extensive use of the additional interfaces the emPC-A/RPI offers.
