Arduino Opta
Overview
Arduino Opta® is a secure, easy-to-use micro PLC with Industrial IoT capabilities. Designed in partnership with leading relay manufacturer Finder®.
When programmed with Busroot's DAU (data acquisition unit) code, the Arduino Opta becomes a simple and reliable way to communicate shop-floor signals directly into the Busroot platform.
Setup
The device must be supplied with 12-24V DC, via the +/- pins marked on the top left of the unit, and will not consume more than 2.2W of power. Please note, the pins marked A(-) and B(+) are for Modbus only, and should not be connected to power.
Pins I1 to I6 on the top side should be used to input DC signals up to 24v. Pins I7 and I8 are specifically for analog signals between 0 and 10v. The 4 relays on the bottom side are not used.
Each of the top 8 pins can be used to capture HIGH/LOW signals from the machine or system being monitored.
The device is shipped pre-configured to connect to WiFi and relay data back to Busroot.
Once setup, please inform your Busroot account manager (or email [email protected]) which details on the device ID (printed on front), the connected machine and pin usage.
Connectivity
By default the DAU will send data via WiFi over port 1883 and 1885 (MQTT). The destination of this MQTT traffic will be eu-west-2-1.busroot.com (IP: 18.135.102.39) or eu-west-2-2.busroot.com (IP: 3.9.14.134)
