MOD 30ML Functions
INTRODUCTION
SECTION 1
INTRODUCTION
1.1 GENERAL
This document includes database reference information and application examples to aid in
configuring a MOD 30ML Controller using the Visual Application Designer (ViZapp). Information
on database organization, database memory block structures and the logic control portion of this
controller is described in other database reference books as described in Section 1.4. The user
of this document should be familiar with the architecture of the MOD 30ML Controller,
configuration capabilities, and message handling capabilities using either the Instrument
Communications Network (ICN) or the Modbus Protocol. For users developing their own runtime
interface, this document includes attribute numbers and data value number information.
1.2 OVERVIEW OF INSTRUMENT SOFTWARE
The MOD 30ML Controller is an intelligent data acquisition and control device with a
configurable display of six lines, three bars and up to four segments per bar. This instrument
consists of a central processor that communicates to highly modular process I/O and
communications modules. User integration of analog and discrete signal conditioning is
provided on a point-by-point basis. This unique modularity permits the product to be
configured with just the functionality that is required for each application. In addition to the
display formatting capabilities, this identity module provides logic, sequential and regulatory
control functionality. Functionality within this identity module supports basic analog and
digital I/O with filtering and linearization, system interface consistent with MOD 30
instruments, timers, process alarms, supervisory message handling, evaluation of event
equations and PID block functions.
1.3 DATABASE CONFIGURATION AND RUNTIME SUPPORT
ViZapp is used to configure the database
through a Modbus or Instrument
Communication Network (ICN). The
program requires a Windows NT/2000/XP
type personal computer. A series of
interactive displays is used to define block
parameters. After generating the
database, it can be saved to disk and
downloading to the instrument. Once a
database is downloaded to the instrument,
it can be ported to other instruments using
an optional portable memory module and
uploaded to the configurator again if
necessary. See Section 1.4, Related
Documentation for required supporting
documentation.
The creation of interface files for use with pc based runtime packages is also supported.
