7.1.2.5 Configuration
The configuration of input and outputs is set-up in the ".cfg" file.
This only exists for the Level Crossing Monitor to maintain
consistency with the Telemetry systems which share the same data
generation program.
It contains one, one line entry of the
form: ss bb cccccccc
where
ss is the station number, this is normally 01.
bb is the board number, this is normally 01.
cccccccc is the IO configuration for each word of the board. Starting
at input word one, which contains bits 1 to 8 and finishing on word
8, which contains bits 57 to 64. An I configures the word as Inputs,
and an O configures the word as outputs. The standard value for
this is "IIIIIIIO".
For example a normal configuration file will
contain: ; station board_address BOARD
CONFIGURATION ;
01 01 IIIIIIIO
7.1.2.6 Expression data name
The expression data name is the first non-comment line in the
".exp" configuration data file. The first 40 characters of this line
appear in the Level Crossing monitor EPROM. They are used to
identify the configuration data in use by a particular level crossing
monitor.
The first non-comment line of the ".exp" file must be the Level
Crossing name and the date of the last alteration to the particular
configuration data files. The normal format is “000 Generic,
Generic
Rd 000.00 07/09/94”.
