ClearSCADA and SCADADroid

Utilize Your Existing Database to get SMS Alarms, direct to your Operators

With network upgrades happening all over the world as we begin to prepare for the inevitable switchover to a 5G infrastructure, many cellular providers are starting phase-outs of their existing 3G technology. With Verizon already announcing the end of its 3G service at the end of 2019, this has left many ClearSCADA users in need of cellular callout options scrambling to find something to fill the upgrade gap. A variety of LTE capable solutions exist, but many require a duplication of databases and may require expensive software or costly time spent on training operators to implement. The issue can be compounded when solutions may not work with your existing IT or cellular provider infrastructure, adding layers of complexity.We have heard your feedback, and today are happy to announce that Reonix Automation has introduced capability into its new SCADADroid® R2+ line of 4G LTE capable remote monitoring devices to provide a reliable GSM Modem solution for ClearSCADA. Through a simple Ethernet connection, utilizing the TCP protocol, the SCADADroid R2+ can be configured to act as an SMS Pager over ClearSCADA’s built-in SMS Service, giving you the capability to…
  • Utilize your existing ClearSCADA database of alarms, users and setpoints to get notifications out to a multitude of operators’ devices without the need to manage a separate system
  • Acknowledge alarms with user-specific codes, only if you choose to enable two-way communication
  • Have peace of mind through SCADADroid®’s built-in communication overview, providing you with a secondary point to see all communication history for each device

The SCADADroid® R2+ can do this all while retaining its many robust monitoring features. Meaning you can still utilize Modbus TCP/IP communications to tie directly to a PLC or simply use the device’s on-board 8 digital inputs for any supplementary site-specific alarms. This, combined with SCADADroid®’s VPN Gateway capability give you the ability to change any SCADADroid® settings, or even provide secure access to other devices connected to it, remotely from the comfort of your office.

The entire setup of the integration can take as little as 15 minutes. It consists of:
  • SCADADroid R2+ SetupConnect the device to a local computer, log in through any major browser to the default IP Address (192.168.1.15)
  • On the Overview page, ensure cellular connectivity exists and the signal is sufficient
  • Change the device’s IP to one which aligns or doesn’t conflict with your existing network
  • ClearSCADA Setup (in your existing database)Create a new SMS Service:
    • Right Click > Create New > Pager > SMS Service
    • Enable the Service: Click once on the new SMS Service and under the SMS Service Tab > Enable the ‘In Service’ checkbox > Enable the ‘Process Incoming SMS Messages’ checkbox> Click save icon in top left corner
    • Create a new SMS Pager Channel: Right Click > Create New > Pager > SMS Pager Channel
    • Link SMS Pager Channel to the created SMS Service under the: Click once on the new SMS Service and under the Channel Tab > Enable the ‘In Service’ checkbox > Click the ‘…’ button next to Pager Service, locate the SMS Service which you created in Step 1. and highlight it > Click OK > From ‘Line Speed’ select 115200 Bits/second > Change Modem Command to read “AT” > Click the save icon in the top left corner
    • Change the connection type: Under the Connection Tab > Change Connection Type to TCP/IP > Under Host Address input the SCADADroid R2+ IP Address which you established in Step 3 of the SCADADroid Setup > Change the Port to 2002 > click the save icon in the top left corner of the screen.
    • Enable the SMS Service as a mode of notification for your contacts: Locate a user > Click once on the user > Under the Contact Information Tab ensure that the user’s phone number is present under ‘Pager ID’ > Click the ‘…’ button next to Pager Service, locate the SMS Service which you created in Step 1. and highlight it > Click OK > Enable the ‘SMS Commands’ checkbox

MQTT, Industry 4.0 and the Future of Automation

How Remote Monitoring can be Revolutionized by MQTT
To speak to the issue of telemetry like MQTT, it must first be put into context. Why a protocol can revolutionize an industrial application depends on how industry will be conducted, and what tools will be used in the near and far futures –so as to avoid investment in soon-to-be-outdated control systems.Industry 4.0, a term describing the future of primary, secondary, and even tertiary industrial processes,will heavily rely on leveraging a massive flow of data –between end-users, Industrial & Consumer IoT devices, Intranets, Big Data, and perhaps even Blockchain. This transformation will probably involve Artificial Intelligences (or if not quite that level of machine cognition, at the very least,machine learning), and it will definitely involve machine to machine (m2m) interface and processing.
Machine to machine interface and communication protocols are key to the future of industrial automation, as stringent industrial control system requirements will soon be met by rapidly improving standards in the IoT environment; IoT as applied to industry is now known as IIoT, but we will likely see an integration between the two.Events are the impetus for administrative operators responding to alarm conditions, and for now the actionable response is often left to humans. But soon, IIoT devices will have complex responses to contingencies based on acquired data, and much of SCADA’s supervisory level(and beyond to the production and scheduling levels),can be automated for better efficiency. Such a shift in procedure will free up your operational personnel’s attention–diverting their hands and eyes from HMI terminals, and towards other areas requiring attention. This means rolling with the momentum of the Industry 4.0 Revolution rather than struggling against it or missing out entirely. For the time being, operators are content to remain in control at the supervisory level of industrial control systems. What used to be constant supervision of industrial control systems now requires response only when critical events trigger alarms, at least in a SCADA setting. The role of the human being in this process is now much more meaningful. It makes the operators in charge of event response an executive rather than a sentry, and the automation of datalogging presents the opportunity to ensure that they are not overburdened with Quality Management or Safety Standard documentation as well.
Development of SCADA Hardware and Software
The development of SCADA equipment is varied and few solutions on the market are identical. Multifunctional equipment is a de facto market offering, so products with an initial function in a SCADA setup may often take on complementary functions, rather than having a dedicated function, since fragmenting the required equipment would make clutter for the plant operators. The downside to a wide variation in equipment function is the complexity of the setup, necessitating the consulting services of systems integrators to ensure that equipment from different companies can be utilized, rather than submitting to dependency upon a SCADA equipment sales company to do their customer’s purchase planning for them.But the most exciting benefit of IIoT functionality in a multipurpose device is how it enhances and integrates other digital and physical features into a much broader virtual process. One such IIoT protocol is MQTT, a reliable protocol first developed by IBM. Message Queue Telemetry Transport is a lightweight protocol that can ration the transfer of data packets going over cellular by way of its queuing procedure.Essentially, an MQTT device at a remote site can act as an IIoT Gateway, bridging smart field devices to cloud servers. Minimal transfer from a remote location to a cloud based broker, is further distributed to the edge of the wired network (if the centralized distributed network on the internet is called a cloud, then server computing localized nearer to the IoT field level and control level devices can be called a ‘fog’(i.e. clouds reaching down into a city street),meaning that only essential data is transferred over cellular, and telemetry transports in carefully measured quantities. High priority is fire-and-forget, whereas lower priority data packets will queue for the right network latency, applicable to the purpose of saving on cellular data consumption overall. Lower priority queuing preserves bandwidth by waiting for data bottleneck at the gateway to clear before sending
Data Efficiency and MQTT: Ways this Lightweight Protocol Can save on Cellular Costs Today
1.Queuing: Communication limited to a small code size allows the m2m client to send published values (data points)collected from the m2m server device(such as a sensor)to the cloud-computing broker, where any access or further data processing can be sent to local area networks unconstrained by data restrictions; the m2m part of the telemetry compresses and rations the packets sent out, whereas the machine to cloud, and machine to human portions of the Pub-Sub (publish and subscribe) telemetry can relay back and forth more freely.
2.Actionable Messages: Actionable data sent over MQTT, as with digital or analog I/O for instance,saves enough money to give the operators the choice between using a cell budget to access and reconfigure the setpoints of field bus clients remotely, through VPN for instance, or sending personnel to deal with the remote site if remote access fails to resolve the problem.
3.Telemetry Prioritization: GPS is a data efficient technology when the positioning results are communicated to a networked device over MQTT. If your remote monitoring is on the move, as with a fleet management application, then it’s imperative that positioning data be of the right level of importance, and that it be sent in such a way that keeps cellular data consumption costs low–as there’s no doubt that mobile GSM expenses can hurt a company’s bottom line, especially where less than critical information must consume more bandwidth to reach the MQTT Broker. MQTT as a protocol makes assessments of the event-data’s urgency, and queues events’data for efficient transport.
4.Alarm Conditions Only: With a fieldbus setup like Modbus, polling events communicable over MQTT makes SCADA a low-cost proposition. Rather than sending Modbus read-commands over cellular to the supervisory level client, the Modbus control level client can queue alarm condition data and publish events to the MQTT broker. From the broker, the supervisory level(using devices such as personal computers, smartphones, and tablets)can be notified of subscribed-to topics and can publish new setpoints back to the Modbus client via the cloud broker.
5.Computing on the Edge: At a remote site IIoT integrated via MQTT, multiple sensors and (or) data processing units can communicate with one another, and if necessary, can be formed into a distributed cloud-like processing network that serves as a local extension of the cloud –in essence, fog computing or edge computing. A fog will be able to roll down from the cloud to the remote site, and much of the data processing work that would be done in the cloud (distributed processing over the internet) can be done right there at the remote site; rolling the fog down to your remote site would mean that only the most essential data would be published to client devices via MQTT Broker, which in turn would mean that cellular data consumption would be kept to a minimum.
