Labeling Dictionary S

Sampling Rate
The frequency with which samples of a physical variable, such as sound are taken. The higher the sampling rate, the more closely the digitized result resembles the original.
SCADA
Abbreviation for Supervisory Control and Data Acquisition. The level of applications that monitor and control devices such as programmable controllers. These systems are usually PC or workstation based. Is typically accomplished in industrial settings by means of microcomputers.
Scan
To examine data from process sensors for use in calculations. A single sweep of PLC applications program operation. The scan operates the program logic based on I/O status, and then updates the status of inputs and outputs.
Scan time
The time to completely execute a PLC program once, including I/O update. Semiconductor any of a class of solids having higher resistivity than a conductor, but lower resistivity than an insulator. Important semiconductors are silicon, germanium, lead sulphide, selenium, silicon carbide and gallium arsenide. Semiconductor materials are the basis of all integrated circuits.
securPharm
German pharmaceutical manufacturers, wholesalers and pharmacists initiative aimed at testing whether medicinal products are genuine.
Sensor
A transducer whose input is a physical phenomenon and whose output is a quantitative measure of the phenomenon.
Sequence control
The control of a series of machine movements, with the completion of one movement initiating the next. The extent of movements is typically not specified by numerical input data
SERCOS
Abbreviation for Serial Real-time COmmunications System. The standard (IEC-61491) for interfacing between controllers, digital servo drives, and I/O devices. The SERCOS interface is implemented with fiber optic cable that increases the reliability and noise-immunity of a multi-axis control system.
Serial interface
Relating to the electrical interconnection between the computer and peripheral units (for instance, a printer) in which data is transmitted 1 bit at a time over a single wire.
Serial port
A computer interface for connecting to external drives where data is transferred serially.
Serialization
Serialization is the process that manufacturers go through to assign and mark each of their products with a unique identifier such as an Electronic Product Code (EPC).
Servo mechanism
An automatic, closed-loop motion control system that uses feedback to control a desired output such as position, velocity, or acceleration.
Servomotor
A power-driven mechanism that supplements a primary control operated by a comparatively feeble force (as in a servo mechanism).
Shaft
A bar, usually of steel and usually round, to support rotating parts or to transmit power.
Singulation Mode
Mode where packages are automatically separated while traveling down the conveyor.
Six Sigma
Six Sigma is a business management strategy originally developed by Motorola, USA in 1981. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects (errors) and minimizing variability in manufacturing and business processes.
SolidWorks
A 3D mechanical CAD (computer-aided design) program that runs on Microsoft Windows and is being developed by Dassault Systèmes SolidWorks Corp., a subsidiary of Dassault Systèmes, S. A. (Vélizy, France). SolidWorks is currently used by over 1.3 million engineers.
Sorter
A conveyor that receives mixed unit loads and discharges them to segregated spaces or conveyors in response to an automatic dispatch control.
Specifications
The engineering requirements for judging acceptability of a particular characteristic. Chosen with respect to functional or customer requirements for the product, a specification may or may not be consistent with the demonstrated capability of the process (if it is not, out-of-specification parts are certain to be made).
Speed
The rate at which product moves on conveyor.
Speed reducer
A power transmission mechanism designed to provide a speed for the driven equipment less than that of the prime mover. Speed reducers may have either constant speed or adjustable speed. They are generally totally enclosed to retain lubricant and prevent the entry of foreign materials.
Sprocket
A wheel with suitably shaped and spaced cogs or teeth to engage with the links of a chain.
Standards
A rule or measure by which a finished product will be measured. A rule established to create a yardstick for measuring or guiding quantity, quality, value, etc. A vehicle for communication.
Statistical Process Control (SPC)
A quality control method focusing on continuous monitoring of the process rather than the inspection of finished products, with the intent to achieve control of the process and eliminate defective product.
Statistical Quality Control (SQC)
Applies statistical techniques to the observed characteristics of a process.
Strategies
A strategy is a series of planned and sequenced tasks, which together allow for achievement of the critical success factor. Strategies must be clearly stated, observable and measurable.
Subassembly
An intermediate level assembly used in the production of an upper level.
Supervisory control
The use of computers to accomplish operator interface, data acquisition, process monitoring, and some degree of production control.
Switch
A device for making, braking, or changing the connections in an electric circuit. In controller practice, a switch is considered to be a device operated by other than magnetic means.
Synchronous assembly
An assembly system where various assembly steps are occurring in series, and have similar timing requirements, requiring one start-stop signal.
System Integration
System integration is the bringing together of the complete line subsystems into one system and ensuring that the subsystems function together as a system.
