3.1 Overview
The keyboard controller checks the 10 x 8 keyboard matrix of the SIMATIC PC. In
this matrix the functions of a standard AT keyboard can be assigned to any key. An
additional standard AT-MF II keyboard can be connected (to the front or back of
the unit).
The key assignment, which is exclusively determined by software, can be modified
at any time without requiring any further technical means. Programming the is
executed via the keyboard interface between PC and keyboard controller. All
settings are saved in the controller integrated EEPROM. The controller is backed
up by a hardware watchdog circuit.
The key assignment can be re-defined with the programming software (which is
included with the PC).
The programming software is independent on the operating system. To carry out
the programming, you must first create a boot diskette. To do this, follow the
instructions in the CD Documentation and Drivers.
3.2 Syntax and Structure of the Configuration File
In order to assign parameters to the keyboard controller, you must first create a
configuration file (text file). *.key must be selected as the file type. The easiest
method is to copy and then adapt the configuration file for standard parameter
assignment. A printout of this file can be found in Section 3.5.
The configuration file consists of lines of text. In order to set a particular function,
you must enter a keyword followed by other parameters. The keyword must always
be located at the beginning of a line. Any number of blanks can be entered
between the keyword and the parameters. It is also possible to enter space lines to
make the text easier to read. A comment is introduced by a ‘;’ and can begin at any
position in the line.
