OVERVIEW
The Quick Response Slave module (IMQRS02) brings four ana-
log and three digital process field signals into the INFI 90 sys-
tem for processing and monitoring. It outputs four digital and
two analog signals for process control. The Quick Response
Slave (QRS) module is an interface between the process and
the INFI 90 Process Management System. Master modules per-
form the control functions; slave modules provide the I/O.
This manual explains the purpose, operation and maintenance
of the slave module. It addresses handling precautions and
installation procedures. Figure
illustrates the INFI 90 com-
munication levels and the position of the QRS module within
these levels.
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the QRS module. A module
SHOULD NOT
be put into operation until this instruction is
read and understood. You can refer to the Table of Contents to
find specific information after the module is operating.
MODULE DESCRIPTION
The QRS consists of a single printed circuit board (PCB) that
occupies one slot in a Module Mounting Unit (MMU). A
dipswitch on the PCB configures each of the analog outputs;
jumpers configure each of the digital inputs. Each analog input
is configured on its respective Termination Unit (TU) or Termi-
nation Module (TM).
Two captive screws on the faceplate secure the module to the
MMU. A front panel LED indicates the module status.
The slave module has three connection points for external sig-
nals and power (P1, P2 and P3). P1 connects to logic power that
drives the module circuits (refer to Table
). P2 connects it to
the slave expander bus to communicate with a Multi-Function
Processor (MFP) module (refer to Table
). The digital and
analog signals are input and output through connector P3
using a cable connected to a TU/TM (refer to Table
). The
terminal blocks (physical connection points) for field wiring are
on the TU/TM.
