How to change the pulse input voltage threshold on your Octopus

Pulses offer a simple way to output the amount of energy that has been measured by a meter (electrical, thermal, gas, water, etc). Pulses are brief bursts of DC (direct current) voltage, with each burst having an abrupt beginning (or rise) and an abrupt ending (or decay), and their output is typically proportional to energy…

Connect your Carlo Gavazzi EM21 meters to Wattics with the Octopus Gateway

  1 Electrical Wiring     Isolate unused RS485 cable wires before powering up the Octopus to avoid unexpected shorts. Switch on the resistor for daisy chain installations. Write down your meter’s Modbus/rs485 settings: Modbus address / baud rate / number of bits / parity / stop bits   For more information check the following…

Configuring your Octopus Gateway with the Wattics Octopus Software Tool

This post outlines the configuring steps for the Wattics Octopus Software Tool, for configuration of data collection for your Wattics Octopus. This document should be used to: Familiarise yourself with the Octopus Software Tool. Quickly start using the Octopus Software Tool to commission and operate your Octopus Gateway and I/O Extension units   NOTE: Read…

Connecting RS485 Modbus devices to the Wattics Octopus

This post outlines the wiring steps for connecting RS485 Modbus devices (e.g. Modbus meter) to the Wattics Octopus. Before you start please make sure you have all material available: Modbus device (e.g. Modbus meter) Octopus Gateway unit RJ12 interface cable, to connect the Modbus device to Octopus Gateway unit     RS485 (Modbus) pinout The…

Connecting pulse outputs to the Wattics Octopus

This post outlines the wiring steps for connecting pulse units to the Wattics Octopus Gateway and I/O Extension units. Pulse units may come from pulsed meters such as Utility electricity/gas/water meters, electrical, water, gas and heat submeters, PLCs and other production control systems. Once the pulse units wired, the Octopus devices must be configured to…

Connecting temperature probes to the Wattics Octopus

You can connect the 2-wire temperature probes to the Octopus Gateway or I/O Extension units in any available analog input. NTC probes with resistor values from 5k and up (NTC5k, NTC10k, etc) are recommended, with 0-10V or 4-20mA output. Depending on the output of our temperature probe (0-10V or 4-20mA), you will need an Octopus…
