SECTION 1 - INTRODUCTION
OVERVIEW
The IMCIS12 Control I/O and IMQRS12 Quick Response I/O
modules bring four analog and three digital process field sig-
nals into the INFI 90 OPEN system for processing and monitor-
ing. They output four digital and two analog signals for process
control. The control I/O (CIS) and quick response I/O (QRS)
modules are interfaces between the process and the INFI 90
OPEN Strategic Process Management System.
The IMCIS12 and IMQRS12 modules are functionally the
same; however, the QRS module provides approximately ten
times faster response for the analog inputs. By doing this, the
input signal noise rejection is lower for the QRS module than it
is for the CIS module. The process requirements determine the
module to use for your application.
NOTE: In this instruction, any reference to I/O module means either
IMCIS12 module or IMQRS12 module.
Control modules (e.g., MFP modules) perform the control func-
tions; I/O modules provide the I/O to the control modules.
This manual explains the purpose, operation and maintenance
of the I/O module. It addresses handling precautions and
installation procedures. Figure
illustrates the INFI 90
OPEN communication levels and the position of the CIS and
QRS modules within these levels.
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the I/O 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 CIS and QRS modules consist of a single printed circuit
board (PCB) that occupies one slot in a module mounting unit
(MMU). Jumpers on the printed circuit board configure each of
the analog inputs, analog outputs and digital inputs. Analog
inputs can also be configured on its respective termination
unit (TU) or termination module (TM).
Two captive screws on the faceplate secure the module to the
MMU. Two front panel LEDs indicate the module status.
