6.1 CONTROLLER MODULE
The function of the Controller Module is to oversee the operation of the entire GARD 8000 system.
This module interfaces the user to the system, and allows the user to configure the function modules.
The unit contains a PowerPC (PPC) that runs the web server and translates user requests into
commands to the other modules.
The Controller Module also has a Digital Signal Processor (DSP) that is used to process logic data. The
basic architecture of the GARD 8000 is extremely flexible and open-ended. Many different hardware
configurations may be put together, and each of these may be configured to perform in different ways.
This is done, by taking the logic data from various components, combining them, and then sending the
result back out to the modules.
This logic data is fed into the logic processor and sent back out using the Logic Bus. The logic
processor can combine signals (using ANDs, ORs, etc) and process them using latches or timers. This
processing is continuously performed by the DSP in real-time.
A Controller module can be installed in slots 10 or 11. In a redundant system, a Controller module is
installed in slots 10 and 11.
Refer to Figure 6-3 and Table 6-2 for the locations and functions of the controller module, controls and
indicators.
