EDMS
Abbreviation for Engineering Document Management System.
EEPROM
Abbreviation for Electrically Erasable Programmable Read Only Memory.
Efficiency
Calculated as machine uptime divided by the total of uptime and downtime. This may also be displayed as the number of running hours divided by the number of scheduled running hours.
 
Electronic Data Interchange (EDI)
Electronic Data Interchange is a standard for automated exchange of business documents that allows purchasers and suppliers to exchange digital paperwork, such as purchase orders, invoices and other business documents, and to perform electronic funds transfers.
Electronic Product Code (EPC)
The Electronic Product Code is designed as a universal identifier that provides a unique identity for every physical object anywhere in the world, for all time.
Electronic Product Code Information Services (EPCIS)
EPCIS is an EPCglobal standard of GS1 that specifies a uniform way to electronically transmit between trading partners a detailed representation of supply chain events.
EPC network
The EPCglobal Network is a computer network used to share product data between trading partners. It was created by EPCglobal. Basis for the information flow in the network is the Electronic Product Code (EPC) of each product which is stored on an RFID tag or a serialized code.
ePedigree or e-Pedigree
An ePedigree is simply an electronic document which satisfies a pedigree requirement. Refers to a record containing information as defined by law. For example, a drug pedigree is a statement of origin that identifies each prior sale, purchase, or trade of a drug, including the date of those transactions and the names and addresses of all parties to them.
Electrically Erasable Programmable Read-Only Memory
ROM that can be erased with an electrical signal and reprogrammed.
Embedded system
A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function. In some cases, embedded systems are part of a larger system or product, as is the case of an anti-lock braking system in a car. Contrast with general-purpose computer. Defined by Michael Barr, President, Netrino Consultants Network.
Emergency pull cord
Vinyl coated cord that runs along the side of the conveyor that can be pulled at any time to stop the conveyor. Used with an Emergency Stop Switch.
Emergency stop
A sudden cessation of all potentially hazardous motion in a manufacturing system or for a specific piece of machinery. An emergency stop is used to prevent injury to an operator or damage to the mechanical system or the work in process.
Emergency stop switch
Electrical device used to stop machinery in an emergency.
Employee Involvement
A practice within an organization whereby employees regularly participate in making decisions on how their work is done, including making suggestions for improvement, planning, goal setting and monitoring performance.
Empowerment
A condition whereby employees have the authority to make decisions and take action on their own without prior approval.
Encoder
A feedback device which converts mechanical motion into electronic signals. Usually an encoder is a rotary device that outputs digital pulses which correspond to incremental angular motion. The encoder consists of a glass or metal wheel with alternating clear and opaque stripes that are detected by optical sensors to produce the digital outputs.
Encoding
The process of putting information into digital format.
End user interface (EUI)
Interface through which an application program provides information to the machine operator, and acts as the interface method between the human and the equipment/machine (also see Human Machine Interface).
Engineer to order (ETO)
A manufacturing response to demand in which engineering analysis and design occurs for all materials and production activities designated for a specific customer order. ETO may involve the use of a few common raw materials, but requires constructing new bills of materials and routings to complete intermediate items and the end time required.
Engineering change order (ECO)
A formal document that has been signed off by the affected departments and authorizes product definition changes to a drawing, bill of material or routing. It often ties to system planning, scheduling and cost functions by specifying an effectivity date for the items included.
Engineering change request
A document requesting a revision or change to a product or process that optimally includes the reason, urgency level, items and processes affected, and cost/benefit of the change. Signoff by a review board is normally required before the change is enacted.
Engineering change review board
A cross-functional team that analyzes proposed engineering changes for approval or rejection. It normally includes representation from engineering, operations, purchasing, planning, cost accounting and vendors or customers as required and its members are able to evaluate timing and cost/benefit considerations.
Enterprise Resource Planning (ERP)
Enterprise Resource Planning is recognized as a logistical extension of MRP.
EPCglobal
An organization set up to achieve worldwide adoption and standardization of Electronic Product Code (EPC) technology.
Erasable Programmable Read Only Memory (EPROM)
This sounds like a contradiction in terms as ROMs are Read only Memory that by definition cannot be erased by switching off the current. However, EPROM acts as ROM unless special action is taken. An EPROM contains charge in a transistor gate that holds it for up to 10 years. Applying ultraviolet light to the chip's surface dissipates the charge, erasing the memory content and allowing the reprogramming of the chip through the transistor gate using a higher voltage than is normally present on a PC board.
Ergonomics
The science of designing the job, equipment and workplace to fit the worker. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability. Relative to custom automated machinery, it is the practice of protecting human operators from serious or catastrophic injury and from long-term negative effects on health or well-being resulting from the interfacing with systems or processes.
Escapement
In a gravity or power operated package conveyor, a device to permit the release of packages one at a time on demand.
Ethernet
The standard for local communications networks developed jointly by Digital Equipment Corp., Xerox, and Intel. Ethernet baseband coaxial cable transmits data at speeds up to 10 megabits per second. Ethernet is used as the underlying transport vehicle by several upper-level protocols, including TCP/IP.
Explosion-proof
Equipment designed in accordance with existing codes and standards such that it will operate in a specified hazardous environment without causing an explosion. Electrical equipment that must be installed in such locations is especially designed and tested to ensure it does not initiate an explosion, due to arcing contacts or high surface temperature of equipment.
