GENERAL
WARNINGS Equipment Environment
All components, whether in transportation, operation or storage
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to ensure that contact with
energized parts is avoided when servicing.
Special Handling
This module uses Electrostatic Sensitive Devices (ESD).
Output Values During Startup, Reset and Certain Failure Condi-
tions
The digital outputs of the module are de-energized during startup,
reset, and certain failure conditions. Analog output values return to
default values during startup, reset, and certain failure conditions.
These default values are selected using switches mounted on the
module circuit board. The control strategy should be designed to
prevent personal injury, equipment damage and/or return the con-
trolled system to a safe state if the module fails unexpectedly.

SECTION 1 - INTRODUCTION
OVERVIEW
The Quick Response Controller (IMQRC01) is an INFI 90 mod-
ule that performs control schemes using digital and/or analog
input data. The QRC contains on-board circuitry for four ana-
log inputs, two analog outputs, three digital inputs and four
digital outputs. The quick response controller communicates
with other intelligent modules in the system over the module
bus. The module bus provides a means to configure, tune,
monitor and acquire data.
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the quick response controller.
DO NOT operate the module until this instruction is read and
understood. Refer to the table of contents or index to find spe-
cific information after the module is operating.
MODULE DESCRIPTION
The quick response controller is a user-configured device that
executes sequential control schemes. This microprocessor
based module resides in the INFI 90 system. The module can
be configured to any control strategy desired using standard
configuration tools and a defined library of function codes.
MODULE APPLICATION
Control schemes consist of function codes (from the INFI 90
function code library) that are stored in the on-board memory
of the module. Besides executing control schemes, the module
executes self-tests, security functions and bus interfacing.

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 2-1.
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

address. The device address for the quick response controller
is set via an eight position dipswitch.
NOTE: The QRC cannot communicate over the controlway.
Memory
The on-board memory is 32 kilobytes of read only memory
(ROM), 4 kilobytes of random access memory (RAM) and 2 kilo-
bytes of nonvolatile random access memory (NVRAM).
The ROM contains the function code library. The RAM serves
two purposes: holds an operating copy of the configuration
while the module is in the execute mode of operation; provides
temporary storage for in-process algorithms. The NVRAM con-
tains the permanent copy of the module configuration. The
NVRAM of the quick response controller has the capacity for
approximately 199 function blocks.
Machine Fault Timer
The machine fault timer (MFT) is a resettable one-shot timer
that must be periodically set by the microprocessor. Several
conditions detected by the microprocessor will keep it from set-
ting the MFT. They are:
1. Trip block activated.
2. Excessive analog input gain/offset error.
3. Excessive analog output gain/offset error.
4. Power failure/reset during an NVRAM write.
If the MFT times out, the microprocessor halts. The QRC will
not respond over the module bus, and the status LED changes
to red. In addition, the digital outputs are de-energized and the
analog outputs will either hold their last value or go to the
power up preset value as selected during installation.
Digital Inputs/Outputs
There are three digital inputs and four digital outputs
on-board. The inputs are jumper-selectable to be energized by
24 VDC or 125 VDC. The inputs are optically-isolated; outputs
are isolated, open-collector type. The I/O signals are routed to
the NTCS02/04 termination unit through the NKTU01 cable or
to the NICS01 termination module through the NKTU02 or
NKTM01 cable.

DESCRIPTION AND OPERATION
SECURITY FUNCTIONS
I-E96-215A 2 - 3
Analog Inputs/Outputs
There are four analog inputs and two analog outputs on-board.
The inputs must be 1 to 5 VDC analog signals. The outputs are
dipswitch selectable to be either a voltage signal (1 to 5 VDC) or
a current signal (4 to 20 milliamps). The I/O signals are routed
through the same termination unit and cable as the digital I/O
signals.
Digital Control Station Serial Link
Communication between the QRC and a digital or analog con-
trol station is via a five kilobaud, RS-422 serial link. A maxi-
mum of four stations can be daisy chained on the serial link.
SECURITY FUNCTIONS
Two types of security functions are performed: module security
and control input security. Module security is provided by a
machine fault timer (MFT) that is periodically reset by the
microprocessor. If the timer is not reset, it:
•Shuts the module down.
•Turns the front panel status LED red.
•Causes the analog outputs to either hold, go to 0 percent,
or go to 100 percent (user-selectable).
•De-energizes the digital outputs.
•Prevents writing to or erasing the NVRAM.
Control input security is provided by adding function code 31
(test quality) to the configuration. This function tests the qual-
ity of a maximum of four inputs. If the inputs are good, the out-
put of the test quality block is set to Logic 0. If any of the
inputs are bad, the output of the block is set to Logic 1.
Depending on the importance of the input, the block output
can cause transfer of control to a manual/auto station, shut
down the process or send a warning to the user.
Additionally, on-line tests are performed to verify proper hard-
ware operation. If any of these tests fail, the timer is not reset
and status LED turns red. If an NVRAM checksum error is
detected, the module continues operating; however, the status
LED flashes green. After resetting the module, it will enter the
error mode.

CONFIGURATION
A configuration must be defined to determine the operations a
QRC performs on its input signals. This section explains the
function codes that can be used with a QRC. Function codes
are software algorithms that can be configured to execute spe-
cific tasks. A function block in memory has a reference number
(block address) that can be used as an input reference by other
function blocks. The QRC processes defined function blocks in
ascending order.
NOTE: This instruction contains the function codes available to the
IMQRC01. The function codes defined in this section reflect the
function codes that were available at the time the instruction was
created. Refer to the latest
Function Code Application Manual
for
additional function codes.
Function Blocks
NOTE: Refer to the
Function Code Application Manual
for the
specifications and outputs of the QRC function codes.
The range of function blocks for the quick response controller
is 0 through 240. Blocks 0 through 9 are reserved for analog
and logic constants. Blocks 200 through 240 are reserved for
the executive block and outputs of all the fixed address system
blocks. The executive block handles overall module operation.
The fixed address system block outputs can be used anywhere
in the configuration. Blocks 10 through 199 are user-assign-
able. Table 2-1 lists the outputs of the executive block and the
fixed address system blocks.
