Information Function
File
The base hardware information (BHI) file is a read-only file that contains
a description of the MicroLogix 1200 Controller or the MicroLogix 1500
Base Unit.
IMPORTANT
Although the DAT does not allow protected data to be
changed from its keypad, the control program or other
communication devices do have access to this data.
Protection bits do not provide any overwrite protection to
data within the target bit file. It is entirely the user’s
responsibility to ensure that data is not inadvertently
overwritten.
NOTE
•
Remaining addresses within the target file can be used
without restrictions (addresses B51/96 and above, in
this example).
•
The DAT always starts at bit 0 of a data file. It cannot
start at any other address within the file.
