R
RAM
RAM (Random Access Memory) is a read/write memory in which every
memory location can be addressed individually and its contents changed.
RAM is used to store data and programs.
ROM
ROM (Read Only Memory) is a memory in which every memory location
can be addressed individually. The stored programs and data are permanently
programmed at the factory before delivery and are not lost in the event of a
power failure.
RTC
Real-Time Clock
S
SCSI Interface
Small Computer System Interface. Interface for connecting SCSI devices
(hard disk drives, CD-ROM drives).
Serial Interface
Data is transmitted one bit at a time via a serial interface (port); serial
interfaces are therefore slower than parallel interfaces.
SETUP
A program in which information about the device configuration (for
example, the configuration of the programming device's hardware) 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 Memory
Memory submodules in credit-card format for SIMATIC S5 to SIMATIC S7
Cards
which are programmed with the PG 760 PII and can be plugged into an S5 or
S7 programmable controller.
SIMATIC NET
Bus system on the basis of the ETHERNET standard. Components of the
Industrial Ethernet
SIMATIC S5 and S7 series (for example, programming device,
programmable controller, remote I/O) can be networked directly using
SIMATIC NET Industrial Ethernet interface modules.
SIMATIC NET
Bus system on the basis of the PROFIBUS standard. Components of the
PROFIBUS
SIMATIC S5 and S7 series (for example, programming device,
programmable controller, remote I/O) can be networked directly using
SIMATIC NET PROFIBUS.
