DCS & PLC

Distributed control systems (DCS) are widely used in major industries. They are mainly used in plants with continues process having large number of input and output signals, especially analogue signals, and simple or sophisticated control loops. Controllers and workstations are usually distributed in several control rooms all around the plant. They can communicate with smaller control systems of machines, process packages, Emergency Shutdown systems (ESD) and F&G systems to provide supervisory information for plant management. They have data and alarm logging and reporting facilities to provide easy and efficient process management. They can be connected to or be a part of management information systems (MIS) and Manufacturing Execution Systems (MES) to provide required information for enterprise management.

Borna system offers DCS from well-known manufacturers such as:

• Siemens PCS7
• Emerson DeltaV
• ABB

Programmable Logic Controllers (PLC) are smaller control systems which can control small process plants, machines such as compressors and complicated pumps, process packages such as heaters and incinerators, filling and packing machines and so on. They are ideal for processes having discrete I/Os and starting and shutdown sequences. Thanks to fast scan rates of IOs and small cycle time, they could be used to control processes with fast changing stats.

Borna system offers PLC from following manufacturers:

• Siemens
• ABB
• EMERSON
