EPROM/EEPROM Submodules
These are plug-in submodules with EPROM/EEPROM chips. S5 user programs
can be stored on them. These programmed submodules are then plugged into
specially designed slots in the programmable logic controller.
Ethernet
Local network (bus structure) for text and data communication with a transfer rate
of 10 Mbaud.
Memory extensions can be installed in the programming device to increase the
width of the memory.
F
A complete, named collection of information, such as a program, a set of data
used by a program, or a user-created document. A file is the basic unit of storage
that enables a computer to distinguish one set of information from another.
Formatting divides the memory area on a magnetic data medium into tracks and
sectors. Formatting deletes all the data on a data medium. Every data medium
must be formatted before it is used for the first time.
Function keys can be divided into two different types; the normal function keys
which are assigned a particular function of the computer (for example, delete key),
and programmable function keys (softkeys).
