ARM-based IoT gateway kit includes PLC and demo board

Nov 7, 2016 — by Eric Brown — 1,528 views

Eurotech’s Linux-based EDCK 4001 dev kit is built around its ReliaGate 10-11 IoT gateway and middleware, adding a PLC and demo board to mimic sensor I/O.

The EDCK 4001 Everyware Device Cloud Development Kit simulates typical IoT sensor data sources and receivers on a demo board panel controlled by a PLC. This setup is in turn controlled by Eurotech’s ReliaGate 10-11 industrial computer running Yocto Linux and Eurotech’s Everyware Software Framework (ESF) IoT device middleware.

ESF, which is based on the open source Java/OSGi Eclipse Kura application framework for IoT gateways, is offered with a complimentary trial license for Eurotech’s Everyware Cloud (EC) platform. EC allows cloud-based access with monitoring and management of devices, as well as data storage, analytics, and remote software deployments and OTA updates. Features include data retention and retrieval, analytics, dashboarding, and a VPN. The full EDCK 4001 software stack also includes an Oracle Java SE Embedded 8 Virtual Machine.

The EDCK 4001 kit also includes a professional trial license for Bitreactive’s Reactive Blocks visual tool for developing gateway applications from pre-built components. Tutorials are available, along with a pre-installed sample app, in which the gateway and PLC create a link between the cloud and sensor devices.

The 140 x 95 x 45mm ReliaGate 10-11 is the lowest end model in Eurotech’s line of ReliaGate gateways, including its most recent, Bay Trail Atom based ReliaGate 20-25. The gateway runs a Yocto Linux 1.6 stack with 3.14 kernel on the 800MHz Texas Instruments AM3352 Sitara Cortex-A8 SoC. The ReliaGate 10-11 is equipped with 512MB of RAM, 4GB of eMMC flash, and a microSD slot.

The highly customizable device offer a la carte features such as 4-lane, optoisolated DIO, dual, surge-protected RS-232/RS-485 ports, and a serial console. There are one or two 10/100 Ethernet ports, and a range of wireless radios with antennas, including WiFi, Bluetooth LE, RSMA, GPS, and 3G. There are also temperature and accelerometer sensors and other options such as CAN.



DirectLogic DL05

The kit’s PLC (programmable logic controller) is the DirectLogic DL05. The DL05 offers 6KB of memory, 8x inputs, 6x outputs, and 2x COM ports, The device supports MODBUS RTU master/slave, DeviceNET slave, Profibus slave, and Ethernet protocols.

The Demo Board includes a momentary button, 3x on/off buttons, 3x LEDs, an RGB LED, and a quad counter. Cables between all three devices are also provided.
