SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section explains the functions, module circuitry, data and
connections for the Quick Response Controller (IMQRC01). It
also details the function codes available to configure a QRC.
FUNCTIONAL OPERATION
The quick response controller consists of seven major sections.
They are memory, module bus interface, machine fault timer,
digital control station serial link, digital inputs/outputs, ana-
log inputs/outputs, and the microprocessor, timing and con-
trol circuitry. See Figure
.
Microprocessor, Timing and Control Circuitry
The quick response controller uses an eight bit microprocessor
integrated circuit operating at two megahertz. This device con-
trols memory, I/O circuitry and the machine fault timer (MFT).
Additional circuitry provides the proper timing and clock sig-
nals to run the processor and other functions.
Module Bus Interface
The module bus interface on the quick response controller
allows it to communicate with other INFI 90 modules in the
same PCU. Every module on the module bus has a unique
