The GARD 8000 has a logic bus that is used by all the I/O modules and function modules to
communicate status to other modules in the system. The logic bits are assigned in the GARD 8000
logic files. The logic files contain default labels for the logic bits. A typical logic file will contain
generic names for function. Where ever possible the GARD 8000 refers to the logic bits by the labels
assigned to the bits in either the logic files or on the configuration pages of the system. This approach
allows the use of a single logic file in multiple locations without having to create a custom logic file
for each application or location.
The Edit Logic bit screen is used to change the default labels to user defined labels for customizing a
system to a specific location or application. If the user changes the default setting in this screen the
new label will be used by functions in the GARD 8000 system to identify that logic bit.
Bit 0, bit 1 and bit 2 are reserved by the GARD 8000 system and cannot be assigned or changed by the
user.
Bit #:
This is the actual logic bit number on the logic bus. This is a read only field
Logic Bit Label:
This is the present label assigned to a specific logic bit. If the label has not been changed this will be
the label assigned in the GARD 8000 logic file.
Change Logic bit Label:
This is a text field that allows the user to change the label for each logic bit.
Logic bit status:
This indicated the state of each logic bit. A “1” indicates a high logic bit and “0” indicates a low logic
bit.
Save:
The save button saves all changes to the labels. The changes will not take affect until the save button is
pressed. If the user exits the page prior to saving the changes all changes will be lost.
