Advantech B+B SmartWorx SmartSwarm 351

Translate SCADA protocols to IT in real-time without disrupting, interrupting or reconfiguring your existing networks

Introducing the SmartSwarm 351
If you’re an engineer in charge of SCADA systems like MODBUS RTU, you may have been asked by IT or upper management to find a way to translate and release your SCADA data, in real-time, to IT infrastructure protocols like MQTT, JSON so the information is available and understandable to other parts of your organization.

You also know that extracting data, in real-time, from your existing SCADA protocol can be both difficult, time-consuming, and completely disruptive to mission critical tasks where monitoring cannot stop for more than a few minutes, let alone hours or days to replace and reconfigure an existing SCADA master device.

So ultimately, how do you translate and release your SCADA data to IT, in real-time, without adversely affecting your existing SCADA networks in any way shape or form?

This is why we made the SmartSwarm 351.

The B+B SmartWorx SmartSwarm 351 is ultimately a bolt-on, non-invasive physical device that provides an easy and cost effective way to release and translate your SCADA data, in real-time, to a wider enterprise IT environment. And compared to similar devices and solutions out there, it does so without impacting your programming, processes or people.


Get data without getting in the way (non-intrusive)

Instead of replacing the existing SCADA or automation master device like similar devices already on the market, the SmartSwarm 351 connects to the serial data line and ‘eavesdrops’ on the communications between the master and the attached slaves. From this it builds a comprehensive picture of the status of each of the connected devices, in real-time, without impacting any performance of the existing SCADA or automation system:

• Connects transparently to existing system by simple connection across the serial bus.
• Does not require any reconfiguration of the system
• Does not impact performance of the existing system
• Learns about connected devices by simply listening to Modbus traffic

At no time will data of any kind flow back into your existing system. Your system won’t even know it’s there.

Introduction

Seamlessly connect existing Modbus process systems into the IoT While a number of “Modbus to MQTT” gateways exist, most act as the local Modbus master devices, recovering information from a network of connected slaves. This presents a problem for operators of existing process control systems as a Modbus network can only have a single master device. The SmartSwarm 351 overcomes this limitation by transparently “eavesdropping” on communications between the existing master device and the connected slaves. It non-disruptively derives the I/O status of connected devices and uses this information to provide a real time data feed to a connected IIoT architecture.


Data Filtering

Much of the data that the gateway will see in the Modbus network is of little value. If a temperature reading rarely changes, for example, there is no point in reporting it every time it is sampled. For this reason, in addition to enriching the data, SmartSwarm 351 also allows users to configure the triggers that will cause a monitored value to be published. Users can also configure what is published once an event trigger condition is met – this might be just the changed value, a range of data, or all data from the same register type within the RTU. This lets users optimize the traffic across the communications network. At the same time, the gateway decreases the communications overhead and the processing bandwidth needed to handle it.
