Serial interface
Data is transmitted one bit at a time via a serial port. They are used in all applications
requiring minimum wiring and data transfer across greater distances.
Session at once
In session at once, the CD can be written to both with an audio session and a data session.
The two sessions are written to at once (as in disc at once).
SETUP (BIOS Setup)
A program in which information about the device configuration (that is, the configuration of
the hardware on the PC/PG) is defined. The device configuration of the PC/PG 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.
STEP 7
Programming software for the creation of user programs for SIMATIC S7 controllers.
Track-at-once
In track-at-once recording, a CD can be written to in bits in several sessions if the CD was
not closed.
Troubleshooting
Error cause, cause analysis, remedy
User program
The user program contains all instructions and declarations, as well as signal processing
data which can be controlled by the plant or the process. It is assigned to a programmable
module (Module, programmable) (e.g. CPU, FM) and can be granulated into smaller units
(blocks).
V.24 interface
The V.24 interface is a standardized interface for data transmission. Printers, modems, and
other hardware modules can be connected to a V.24 interface.
Warm start
The restart of a computer after a program was aborted. The operating system is loaded and
restarted again. The hot key CTRL+ ALT+ DEL can be used to perform a warm start.
