INTRODUCTION
1.1 GENERAL
This document is the first of two books that includes database reference information for
instruments with logic functionality. Also included is information on database organization and
database memory block structure. The user of this document should be familiar with the
architecture of the MODCELL or the MOD 30ML instrument, 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
Logic functionality provides intelligent data acquisition and manipulation for the highly modular
process I/O and communications modules on the instrument. 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. Logic control identity module functions support basic analog and digital I/O with
filtering and linearization, a system interface consistent with MOD 30 instruments, timers,
process alarms, supervisory message handling, evaluation of event equations and sequential
control capabilities.
1.3 DATABASE CONFIGURATION AND RUNTIME SUPPORT
PC based application builder software is used to configure the instrument database and uses
the Instrument Communication Network (ICN) or Modbus as a serial interface. The software is
a graphics based configuration tool. Users are presented with a work area and icons that
represent various activities that can be performed. This interface offers maximum flexibility in
defining instrument structures and configuring database parameters. After generating the
database, it can be written to disk and must be compiled before 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. Runtime software packages can be
used to define and view the user interface to the instrument.
