Process Control Systems

Process Control

...is a key element in any production or manufacturing process. Control of limits, tolerances and set points are critical to ensure the best possible product is consistently delivered. Complex environments can be brought under control by utilising process control systems with PLC's (Programmable Logic Controllers) at their heart. Using a defined set of logic parameters written into bespoke software, these systems are able to sample signals from a wide range of transducers and decide on the best course of action in a fraction of a second. Often the use of process control systems can enable entire plants or processes to be operated by only a few people sitting at a control screen or SCADA.

 

When selecting a partner to implement or work on process control systems it is important to choose a company that has knowledge of the process. This can help reduce the learning curve and shorten the time to implement a process control system. GSYS have key knowledge in a number of process and production areas.

Typically a process control system would take in information from any number of temperature, pressure, level, flow, vibration etc. sensors signals. These signals would be connected to the different inputs into the process control system based on their type. Temperature, pressure and level transmitters would be connected as analogue inputs. Some types of basic sensor may have just a simple switch as a an output such as a level or vibration switch. These would be connected to the control system via digital inputs. Analogue outputs could be used to regulate flow through a valve whilst digital outputs could be used to turn on or of various parts of a process.

 

Control systems are usually used to control processes categorised into three different types.

  • Discrete - This type of process generally produces a discrete product such as a specific part or piece.
  • Batch - This type of process brings together measured quantities of ingredients to produce the end result such as in the food industry
  • Continuous - This type of process would generally involve an unbroken production line such as producing rolled steel

All three types of process can be automated and some systems even have elements of each which would be called hybrid systems.
