198 Operating Instructions, 11/2010, A5E02669068-02

ESD directive

Directive for using electrostatic sensitive components.

Ethernet

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

10/100/1000 Mbps.

Execute Disable Capability

Hardware implementation that prevents mutual memory accesses by programs and

applications. It is only effective when all relevant system components, such as processors,

operating systems and applications are supported.

Extensible Firmware Interface (EFI)

Refers to the central interface between the firmware, the individual components of a

computer and the operating system. EFI is located logically beneath the operating system

and represents the successor to PC BIOS, focusing on 64-bit systems.

File Based Write Filter (FBWF)

Configurable write filter to protect individual files from write access.

Formatting

Basic partitioning of memory space on a magnetic data medium into tracks and segments.

Formatting deletes all data on a data medium. All data media must be formatted prior to their

first use.

Gender changer

Using the gender changer (25-pin / 25-pin), the COM1/V24/AG interface of the SIMATIC PC

family can be converted to the usual 25-pin male connector.

HORM

Hibernate once, resume many is a method for fast booting from a single Hibernate file that

only needs to be created once. HORM ensures restoration of a uniform, saved system state

when booting. This reduces the writing to a CompactFlash medium to a minimum, for

example, when starting up and shutting down Windows Embedded Standard 2009.

Hot plug

The SATA interface gives the device's hard drive system hot plugging capability. Prerequisite

for this configuration is a RAID1 system with SATA RAID controller (onboard, or slot

module), and at least two SATA removable cartridges. The advantage of hot plugging is that

defective hard disks can be replaced without having to reboot the computer.
