SECTION 1 - INTRODUCTION
OVERVIEW
The Logic Master Module (IMLMM02) is an INFI 90 module that
performs multiple calculating and control functions. The LMM
contains onboard circuitry for eight digital inputs and eight
digital outputs. It also interfaces with up to 64 digital I/O
slaves through the slave expander bus for additional I/O capa-
bility. The logic master module communicates with other intel-
ligent modules in the system by means of 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 logic master module. A
module should
NOT
be put into operation until this instruction
is read and understood. Refer to the Table of Contents or Index
to find specific information after the module is operating.
MODULE DESCRIPTION
The logic master module is a user-configured device that per-
forms digital control schemes. It communicates with digital
slave modules for inputs and outputs, and has a capacity to
handle a maximum of 1,024 I/O points. This microprocessor
based module resides in the INFI 90 system and provides the
ability to perform sequential logic control functions per the
system requirements. The module can be configured to any
control strategy desired using standard configuration tools and
a defined library of function codes. I/O is interfaced using digi-
tal input slaves.
MODULE APPLICATION
Control schemes are designed with operations from the INFI 90
Function Code Library, and stored in the module's on-board
memory.
In addition to executing control schemes, the module performs
self-tests, security functions and bus interfacing.
