Glossary
S
SCSI Interface
Small Computer System Interface. Interface for connecting SCSI devices (hard
disk drives, CD-ROM drives).
Serial Interface
Data are transmitted one bit at a time via a serial interface (port); they are used
where large distances have to be covered using the minimum amount of cabling.
SETUP (BIOS Setup)
A program in which information about the device configuration (that is, the
configuration of the programming device's hardware) is defined. The device
configuration of the programming device is preset with defaults. Changes must the-
refore be entered in the SETUP if a memory extension, new modules, or a new
drive are added to the hardware configuration.
SIMATIC S5 Memory Submodule
Memory submodules for SIMATIC S5 that can be written with the programmer and
inserted in an S5 programmable controller.
SIMATIC Memory Cards
Memory submodules in credit-card format for SIMATIC S5 and SIMATIC S7 which
are programmed with the PG 740 PII and can be plugged in an S5 or S7
programmable controller.
SINEC L2 (PROFIBUS)
Bus system on the basis of the PROFIBUS standard. Components of the SIMATIC
S5 and S7 series (for example, programming device, programmable controller,
remote I/O) can be networked directly using SINEC L2.
SINEC H1(ETHERNET)
Bus system on the basis of the ETHERNET standard. Components of the
SIMATIC S5 and S7 series (for example, programming device, programmable
controller, remote I/O) can be networked directly using SINEC H1 interface
modules.
Software
The collective term for all programs which are used on a computer. The operating
system and the user programs are part of the concept "software".
