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.
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 support@output.industries) which details on the device ID (printed on front), the connected machine and pin usage.
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)
Each pin can be pulsed to indicate when a production cycle has been completed. A pin can be pulsed up to 5 times per second, quicker than this may result in pulses being missed.
The device will communicate a pulse count for each pin every 5 seconds.
An example scenario would be the control signal for an exit gate actuator, or an optical sensor detecting parts exiting the manufacturing process.
Each pin can also be set according to whether the system or process is actively producing products or adding value to the final product, aka Productive vs Non-productive time.
It does not matter if the pin is pulled high or low for either case, the meaning is defined after in the Busroot platform.
The device will communicate the state of each pin every 5 seconds.
An example scenario would be a CNC machine being in its home position to indicate it is not active, or a door sensor on a spray booth.
Pins I7 and I8 can be used to capture analog signals related to the speed of a process related to the machine being monitored.
The voltage range should be 0v to +10v.
An example scenario would be the control voltage of a motor driver for a conveyor belt, or the output of a motion sensor such as a rotary encoder (analog output).
Each pin can be used independently to capture either 'production complete' or 'productive time' signals. This also gives the flexibility to use a single device to capture data from multiple machines, processes or systems.
