SITELINK Server

Voytech

Systems

Limited

Applications

The SITELINK Interface is a

revolutionary new solution for remote monitoring and control of Modbus devices. The product can be used in a wide range of applications including

• Metering

• Environmental control • Condition monitoring

• Fault Detection and Diagnosis On first power-up the product

automatically connects to the

SITELINK Cloud Server which gives access to remote devices using standard internet protocols. No

Connectivity

The SITELINK-3G model is optimised for connection over cellular networks and can reduce data usage by up to a factor of 50 compared with

conventional solutions, significantly reducing data costs. The device also manages data usage to prevent usage exceeding the monthly tariff. SITELINK-3G is supplied

pre-configured with a SIM so that Cloud Connection occurs on power-up.

The SITELINK-ETH model is optimised for connection over broadband and can be installed on site using either Ethernet or WiFi. The SITELINK-ETH is pre-configured to connect to the

Modbus Site Network

Connect up to 32 Modbus devices on the SITELINK RS485 Network

SITELINK Interface

The SITELINK Interface automatically connects to the SITELINK Cloud

Server

SITELINK Cloud Server

The Cloud server gives access to all Modbus Devices on the Site and allows monitoring and configuration of the SITELINK Interface.

Client Software

Access Modbus points in JSON, XML or Plain Text and place directly into spreadsheets, web pages, databases or custom client applications.

Mobile Commissioning

Scan the Sitelink QR code with a mobile phone, the SITELINK Cloud Server will automatically load with the engineering console for the device.

Cloud Server Console

The SITELINK Cloud Server Console allows testing and configuration of the SITELINK Interface from any web browser providing the correct log-in details are supplied.

3G Ultra-Low Data Use

SITELINK uses data compression to achieve ultra-efficient data transfer, allowing high volume data transfer even for small monthly data tarrifs.

Tarrif MB / Month Modbus Queries / Minute

20MB 60

100MB 300

1000MB 3000

SITELINK can achieve up to a factor of 50 reduction in data usage compared with conventional Modbus queries, allowing a 1GB monthly tariff to be reduced to 20MB, which makes it

3G Roaming

SITELINK supports the use of multi-network Roaming SIMs, giving improved connection reliability compared with standard single

network SIMS. Use of Roaming SIMs also simplifies installation by

removing the need for site coverage on a specific network.

3G Data Capping

The SITELINK Cloud Server monitors monthly data usage and throttles data to prevent data overuse penalties.

Modbus Data Access

Modbus points can be read and written using a number of different formats.

Simple https:// queries can be used to directly read and write data points using XML, JSON or plain Text.

Data in Webpages

Javascript and PHP libraries are available to embed data points

directly into web pages. Points can be read and written directly from a

webpage.

Datalogging

A Script library is available for Google Apps to allow data logging directly from Google Spreadsheets. This

allows Cloud datalogging to be easily configured. Generated graphs can be automatically embedded in

Security

The SITELINK system is designed to give end-to-end security to the data path.

Cloud Server connections to site can be protected by IPSec or SSL/TLS tunnels. Client connections to the cloud server are via https:// to prevent eavesdropping.

Access to a specific site requires a secure PIN to be supplied to authorise data access. Multiple PINs can be generated with different access rights to allow basic user to have limited read access while allowing engineers full access.

Cloud Server Deployment

The SITELINK Interface is

pre-configured to connect to the public SITELINK Cloud Server.

Private SITELINK Servers can be deployed for customers who wish to install the servers within VPNs, or who require dedicated Cloud based servers.
