INTRODUCTION
1.1 GENERAL
This document includes database reference information to aid in configuring a MOD 30ML
Controller or a MODCELL Multiloop Processor with regulatory controller software. Information
on database organization, database memory block structures and the logic control portion of
this controller is described in IB-23G600. The user of this document should be familiar with
the architecture of the MOD 30ML or MODCELL Multiloop Processor, 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
MODCELL Multiloop Processor
The MODCELL Multiloop Processor with advanced control identity module is an intelligent
data acquisition and control device. 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 regulatory control functionality, this identity module
provides logic control capability. 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.
MOD 30ML Controller
The MOD 30ML controller includes all functions listed above for the MODCELL Multiloop
Processor. It also includes built-in I/O (2 universal analog inputs, 2 current outputs), one built-
in communications channel selectable for ICN or Modbus RS232 / RS-485, and operator
display capability.
1.3 DATABASE CONFIGURATION AND RUNTIME SUPPORT
PC based configuration software is used to build the instrument database using Modbus or the
Instrument Communication Network (ICN) for communications. A series of interactive displays
is used to define block parameters. After creating the database, a database report can be
generated. 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.
Software packages such as Intellution FIX, Iconics Genesis for Windows, WonderWare
InTouch, and CI Technologies CiTect can be used to define and view the runtime interface to
the instrument.
