SETUP
A program in which information about the device configuration (that is, the
configuration of the hardware on the programming device) is defined. The device
configuration of the programming device is preset with defaults. Changes must
therefore be entered in the SETUP if a memory extension, new modules, or a new
drive are added to the hardware configuration.
SIMATIC S5 Memory Submodules
Memory submodules for SIMATIC S5 which are programmed with the PG and can
be plugged into an S5 programmable logic controller.
SIMATIC Memory Cards
Memory submodules in credit-card format for SIMATIC S5 and SIMATIC S7 which
are programmed with the PG and can be plugged into an S5 or S7 programmable
logic controller.
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".
SOM
Safecard On Motherboard. Consists of a monitoring module on the motherboard,
the driver and the SOM program. Provides functions for monitoring various
temperatures and the program cycle (Watchdog).
Standby
Power saving status: for example, hard disk drive or display turned off.
Startup Disk
The bootstrap instructions coded into a computer's ROM (read-only memory) and
executed at startup. The startup ROM routines enable a computer to check itself
and its devices (such as the keyboard and disk drives), prepare itself for operation,
and run a short program to load an operating-system loader program.
STEP 5
This is a software package which represents the basis for all other STEP 5
software packages. With the programming device (PG), this package is used to
program programmable logic controllers of the SIMATIC S5 family. The language
used is known as STEP 5.
