Programming Device PG 740
C79000-G7076-C742-01
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.
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.
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”.
This is a software package which represents the basis for all other STEP 5
software packages. With the programming device (PG 740), this package is
used to program PLCs of the SIMATIC S5 family. The language used is
known as STEP 5.
The cursor shows where text may be entered, for example, in text editors and
in dialog windows. In many applications the position of the cursor can be
changed by moving and clicking the mouse pointer.
Thin-film-transistor color display
The trackball is used as an input device for programs serviced by a mouse.
On the PG 740, the trackball is integrated in the keyboard.
The software-controlled menus and screens on the monitor through which the
user communicates with the program.
A collection of all the instructions and declarations for signal processing, by
which a system (or process) is controlled or influenced.
