Digalox® IoT Hardware Platform
Data acquisition and machine connection
The data acquisition and machine connection can be done in different ways. Measuring and counting devices of the DPM72 series can be attached directly to the corresponding measuring points of the machines. The DPM72 devices have two measuring channels and serve as direct measuring devices for current, voltage and power, current at the current transformer or shunt. They can also be used as process measuring devices behind a sensor with a standard signal output and as counting devices for pulses or operating hours.
DPM72 process measuring instrument with XBEE radio network
As an extension of the DPM72 models, the devices of the DGLX modular series have a flexible plug-in card system and can be equipped with up to three cards, e.g. standard signal measurement, 3-phase measurement, digital I/O, Pt100 temperature sensor, quadrature encoder, relay, solid state relay, analogue output, etc. The measured values are recorded and processed in the DGLX device. A programmable logic unit enables calculations or the execution of smaller sequence controls directly within the device.
Device networking
The Digalox® Industrial IoT Platform uses an XBEE 2.4 GHz wireless mesh network to connect the devices. The mesh network has the advantage that each network node also functions as a router at the same time. In this way, dynamic networks can be formed with a significantly larger area than would be possible with simple radio links (such as WiFi). The Digalox® DPM72 devices have model variants with an integrated radio module. Other devices from e.g. third-party providers can be connected via the Digalox® XBEE Extender via fieldbus (RS485).
Wireless mesh network
Digalox® Industrial IoT Gateway
The Digalox® Industrial IoT Gateway serves as the central communication node. XBEE wireless mesh network, RS485 fieldbus and another radio link, e.g. Bluetooth Low Energy (BLE), WiFi, or LTE-NB-IoT can be merged and coupled with the Industrial Ethernet. The Gateway communicates with the Transconnect® IoT Software Platform via Ethernet using MQTT in order to enable services such as telemetry, metadata transmission or the reception of control commands.
