Programmable Logic Controller (PLC) – A Meter for Engineers & Automation Professionals

By SATEC (Australia) Pty Ltd | Featured, Industry News | Comments are Closed | 18 September, 2019 | 2

Programmable Logic Controller (PLC), Building Management Systems (BMS) and SCADA generally perform most metering measurement and monitoring solutions. The rise of Energy Management Systems (EMS) is improving electrical metering systems due to several factors, particularly since electrical measurements and monitoring applications can be so vast in their respective applications.

There is a significant difference between low cost metering solutions and advanced smart meters. Subsequently, there is a wide gap between how more advanced solutions can serve applications best instead of traditional low cost metering implementations.

With a PLC with the meter, the concept of Distributed Logic can be realised. Localised control is possible with simple use of programming software, instructing the meter to perform a wide range of tasks usually done by traditional methods.
Examples of such applications are: Demand Response, Demand-Side-Participation billing applications, Fast-Demand-Management, Enhanced Diagnostics, Auto-Load-Shedding, Change-of-State Notifications, Pulse Counting (water, gas, thermal metering), Phase Failure/Reversal Relay, etc.

The Technical Details

Through use of the embedded Programmable Logic Controller, Distributed Logic can be achieved enhancing control systems by improving communications bandwidth. Instead of a traditional ‘polling’ structure, the SATEC meters can send messages to BMS or SCADA on event driven applications.

This concept can also lessen the burden on scan-time, improving code efficiency and effectiveness. SATEC’s embedded PLC operates in a single-cycle, giving applications 20ms throughput @ 50HZ. Therefore, improved monitoring of assets is assured.
Demand Response applications are served best by various approaches. First, the meter can send messages to the control system when ‘Demand Thresholds’ have been met, or a triggered parameter is observed by the meter. Another approach is for the meter to perform an operation of a relay, to isolate and operate a respective load such as a pump or fan.

Data communication efficiency is also achieved within the meters. A ‘block transfer’ of 120x communication-registers in a ‘single-scan’ significantly improves control system throughput ability. Traditionally, ‘multiple-scans’ are performed by BMS/SCADA whereby SATEC meters allow for improved communication solutions.

16-Bit Scaled Data is provided to ½ data packet transmission size. However, 32-Bit structured data can also be obtained from the meters, which is more commonly used. The key point is that SATEC meters can provide more effective, efficient and lower bandwidth communication techniques with training and awareness of such features and benefits.

In summary, extensive applications can be achieved using these automation & control philosophies. The true benefit of a smart meter can be understood and achieved. Smarter than your average meter, the SATEC Embedded PLC is the choice for Engineers, Automation and Metering Professionals.

    The Evolution of Smart Metering Standards: What’s Next for Compliance and Innovation?

    By SATEC (Australia) Pty Ltd | Comments are Closed

    Smart metering has revolutionised the way energy is measured, managed and consumed. With its ability to provide real-time data on energy usage, smart metering plays a vital role in modernising energy grids and improving the efficiency of energy markets. However, as this technology continues to evolve, so too must the standards that govern it.
