The LED studio's SCADA (Supervisory Control And Data Acquisition)solution can be either internal or external to us. We have our own internal software skills to tailor a bespoke software package to your needs, but also have no problem interfecing with existing external packages.
Supervisory Control and Data Acquisition (SCADA) can be defined as a computer system for gathering and analyzing real time data or industrial control system (ICS) that is used to control and keep track of an industrial process or entire plant environment in industries like energy, transport, water and waste control, telecommunications, food production, process and oil and gas refining.
A SCADA system usually consists of the following subsystems:
Now The LED Studio can add to this list
- Remote terminal units (RTUs) connect to sensors in the process and convert sensor signals to digital data . They have telemetry hardware capable of sending digital data to the supervisory system, as well as receiving digital commands from the supervisory system. RTUs often have embedded control capabilities such as ladder logic in order to accomplish boolean logic operations.
- Programmable logic controller (PLCs) connect to sensors in the process and converting sensor signals to digital data . PLCs have more sophisticated embedded control capabilities, typically one or more IEC 61131-3 programming languages, than RTUs. PLCs do not have telemetry hardware, although this functionality is typically installed alongside them. PLCs are sometimes used in place of RTUs as field devices because they are more economical, versatile, flexible, and configurable.
- A telemetry system is typically used to connect PLCs and RTUs with control centers, data warehouses, and the enterprise. Examples of wired telemetry media used in SCADA systems include leased telephone lines and WAN circuits. Examples of wireless telemetry media used in SCADA systems include satellite (VSAT), licensed and unlicensed radio, cellular and microwave.
- A data acquisition server is a software service which uses industrial protocols to connect software services, via telemetry, with field devices such as RTUs and PLCs. It allows clients to access data from these field devices using standard protocols.
- A human–machine interface or HMI is the apparatus or device which presents processed data to a human operator, and through this, the human operator monitors and interacts with the process. The HMI is a client that requests data from a data acquisition server.
- A Historian is a software service which accumulates time-stamped data, boolean events, and boolean alarms in a database which can be queried or used to populate graphic trends in the HMI. The historian is a client that requests data from a data acquisition server.
- A supervisory (computer) system, gathering (acquiring) data on the process and sending commands (control) to the SCADA system.
- Communication infrastructure connecting the supervisory system to the remote terminal units.
- Various process and analytical instrumentation...
SCADA is primarily a computer based system continuously gathering and analysing data in real-time, processing and reporting it.
Traditionally this data is logged on a server or printed, te LED Studio can expand on this by presenting this data to the entire shop floor or individual workstation, the benefits of this being that the operator or line manager/ supervisor is able to respond respond to a situation with immediate effect reducing down time and continued problems carrying on through the line. The alert process can be further enhanced with the added options of sirens or klaxons to be triggered at determined points
