Process control is the ability to monitor and adjust a process to give a desired output. An example of a simple process that is controlled is keeping the temperature of a room at a certain temperature using a heater and a thermostat.

Many types of process control systems exist, including supervisory control and data acquisition (SCADA), programmable logic controllers (PLC), or distributed control systems (DCS), and they work to gather and transmit data obtained during the manufacturing process.

Fundamental Principles of Process Control controlguru. Components of a Control Loop A controller seeks to maintain the measured process variable (PV) at set point (SP) in spite of unmeasured disturbances (D). The major components of a control system include a sensor, a controller and a final control element.

There are three main types of internal controls: detective, preventative, and corrective. Controls are typically policies and procedures or technical safeguards that are implemented to prevent problems and protect the assets of an organization.

Examples of these activities include reconciliations, authorizations, approval processes, performance reviews, and verification processes. An integral part of the control activity component is segregation of duties.

Key Internal Control Activities

• Segregation of Duties. Duties are divided among different employees to reduce the risk of error or inappropriate actions.
• Authorization and Approval.
• Reconciliation and Review.
• Physical Security.

The six principles of control activities are: 1) Establishment of responsibility, 2) Segregation of duties, 3) Documentation procedures, 4) Physical controls, 5) Independent internal verification, 6) Human resource controls. Pick one of the control activities and describe why it is important.

Physical control is the implementation of security measures in a defined structure used to deter or prevent unauthorized access to sensitive material. Examples of physical controls are: Closed-circuit surveillance cameras. Motion or thermal alarm systems.

Physical control refers to mechanical or hand controls where the pest is actually attacked and destroyed. Physical controls are used mostly in weed control. Tillage, fire, removal by hand, grazing and mowing are all used to destroy weeds and prevent reproduction.

Accordingly, Physical Control has penalties which are less severe than OVI. OVI is a moving violation resulting in six points on one’s driver license and a driver license suspension up to three years.

If you are charged with OVI, you may be able to have the charge reduced to a lesser offense. In some cases, an OVI may be reduced to Reckless Operation of a Motor Vehicle Vehicle, a misdemeanor traffic offense, or even to Physical Control of a Motor Vehicle While Under the Influence.
