Glossary

E

EIDE

Enhanced Integrated Drive Electronics. An extension of the IDE standard, EIDE is a hardware interface standard for disk drive designs that house control circuits in the drives themselves. It allows for standardized interfaces to the system bus while providing for advanced features, such as burst data transfer and direct data access. EIDE accommodates drives as large as 8.4 gigabytes (IDE supports up to 528 megabytes).

Energy Options

With Energy Options, you can reduce energy consumption of your computer while it always remains to be ready to use. This function can be configured in Windows via Settings > Control Panel > Energy Options.

EPROM/EEPROM Submodules

These are plug-in submodules with EPROM/EEPROM chips. S5 user programs can be stored on them. These programmed submodules are then plugged into specially designed slots in the programmable logic controller.

Ethernet

Local network (bus structure) for text and data communication with a transfer rate of 10 Mbaud.

Extended Memory

Memory extensions can be installed in the programming device to increase the width of the memory.

F

File

A complete, named collection of information, such as a program, a set of data used by a program, or a user-created document. A file is the basic unit of storage that enables a computer to distinguish one set of information from another.

Formatting

Formatting divides the memory area on a magnetic data medium into tracks and sectors. Formatting deletes all the data on a data medium. Every data medium must be formatted before it is used for the first time.
