1.1 Introduction

The Nimbus Modbus logger is a robust, sophisticated NB-IoT logger/controller with a wide range of input capabilities,

making it ideal for a large number of measurement applications.

Communication to your own server and database can be achieved via the internet or a private APN. The software running

on these servers is supplied free of charge. The Nimbus Modbus Logger has been designed to allow for easy installation and

setup without the need for a complicated server infrastructure. Setup and management software (CloudWorks) is also

supplied free of charge to allow clients to manage their own networks and data. There are no monthly charges for

collecting and hosting data as the client can provide this service themselves.

1.2 Features

Uses NB-IoT technology. NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area

(LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly

improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep

coverage.

Bluetooth interface - setup and manual data collection can be achieved through the Bluetooth interface negating

the need for cables that invariable fail during continuous use.

Optional external power operation with battery failover.

Uses standard off-the-shelf alkaline batteries. This logger uses 3x standard D Cell alkaline batteries that can last in

excess of 5 years under normal usage. Many other loggers use lithium batteries that are expensive and difficult to

obtain. Other problems involving lithium batteries are the restrictions when shipping using airfreight. All lithium

batteries need to be shipped as hazardous cargo that is becoming increasingly difficult to achieve as many airlines

are no longer allowing these batteries on their aircraft.

Onboard Modbus/RS485 interface. The Modbus/RS485 interface can be used on a large number applications or

sensing equipment. This port is also well protected against large voltage transients.

Isolated 4-20mA interface. Used for any sensing device with a 4-20mA output.

Onboard 24V 30mA power generator. The Nimbus Modbus logger can generate a stable 24V output at a maximum

of 30mA allowing for the powering of an external piece of equipment or current loop device eliminating the need

for a secondary power supply. This option will also function under battery operation.

Large onboard non-volatile memory - This logger can record in excess of 20000 datalog records (application

dependent).

Logging intervals from 1 minute to 1 month. Information is internally logged, time and date stamped and

transmitted at programmable intervals.

Remote programming of all setup parameters via NB-IoT link.

Ideal for leak detection, alarming to prevent water loss.

Onboard Bluetooth can stream diagnostic information about signal strength, network status etc.

Touch sensitive button and LED's for manual wakeup to server and diagnostic purposes etc.

1.4 Architecture

1.5 Power Modes

The Nimbus Modbus Logger can operate in one of two power configurations.

Mains powered - in this mode the logger can be continuously connected to the server allowing for the streaming

of live data.

Battery powered - The Nimbus Modbus logger uses standard 'D' Cell alkaline batteries that will last several years

depending on the operation. In this mode, the logger will 'wakeup' (adjustable - normally 6 hourly) and upload its

recorded data to a remote database.

External 12V (8-15V) 2A supply - in this mode the logger can be continuously connected to the server allowing for

the streaming of live data. Batteries can be fitted and the logger will automatically switch to battery mode should

the power fail.

1.6 LED and button functions

On the front of the logger, there are 2 LED's and a touch sensitive 'SELECT' button. Internally on the reverse side of the lid

is the Bluetooth reset button.

1.6.1 LED functions

Blue LED - Bluetooth status

Flashing indicates the Bluetooth is ready to receive an incoming connection

Solid light indicates and active connection

Red LED - Logger status

Solid - Logger is in Command Mode (normally accompanied by an active Bluetooth connection)

Fast flash - Logger is currently initiating a connection to the server

Slow Flash - Connection has been established to the server

1.6.2 Pushbutton Functions

SELECT touch button - Please note, this button is touch sensitive in order to maintain the waterproof status of the housing.

Single short push will toggle the Bluetooth radio on and off.

A push of more than 3 seconds will result in the logger establishing a connection to the server and uploading its

datalog.

BLUETOOTH RESET button - This button is used to reset the Bluetooth interface in the event of a lost password or generally

configuration loss.

The Bluetooth interface of this logger can be configured to have a access password which will limit external access to only

those issued the password. Should this password get lost, the logger can be opened and the Bluetooth interface reset to

disable the security. It is advisable to then connect to the logger again and setup a new password. This is explained later in

this document.

In order to reset the Bluetooth interface, with the housing open, please follow the below procedure.

Remove all power from the logger - remember to remove the batteries if external power is present.

Press and hold the Bluetooth reset button.

Power up the logger again while holding the button. Bluetooth LED will be on confirming the button has been

pressed.

Once the Red Status LED comes on again, the button can be released.

This will now reset the Bluetooth interface.

1.7.1 External Power Supply / Solar System Connection

The CDS545 Nimbus Modbus logger can be powered entirely from an external 12V (8-15V) 2A power supply or solar power

source. Using a solar power source and also populating the logger with alkaline batteries means that the logger can be put

into dual mode. In this mode, while there is solar power available, the logger will remain online with the server. Should the

solar power fail, the logger will automatically switch to 'battery' mode until the solar power source is restored. This is ideal

for remote applications where there is no mains power available and streaming data is required.

1.7.2 Using the 4-20mA loop input and 24V loop power generator

The Nimbus Modbus logger is equipped with a fully isolated (optical) 4-20mA interface. This interface is configured for 2

wire applications and should be connected as below. Please take note of the polarity of the loop connections.

To assist with the powering of loop devices, the Nimbus Modbus logger is equipped with an onboard 24V loop power

generator. This generator is designed to provide the power for devices that source this directly off the loop. Since the

maximum power to flow on a 4-20mA loop, should be 20mA, the generator has been designed to supply a maximum of

30mA. Please note, using the 24V power generator to power a loop device uses a substantial amount of power. For this

reason, in battery operated devices, the loop should only be powered each time the device needs to be read. This can be

achieved by setting the generator into 'Loop Power' mode.

Example configuration of the generator supplying power to a loop powered device

1.7.3 Using the RS485/Modbus interface

The Nimbus Modbus logger is equipped with a fully isolated RS485/Modbus interface. This interface is used for the

connection to specific equipment with these kinds of output interfaces. e.g. ABB Aquamaster flow meters. These available

devices are normally listed in the CloudWorks software as specific applications. Below are the connections for a

Aquamaster flow meter.
