Honeywell TDC 3000X Advanced Process Manager

Functional Description

Functional Overview

Note: This Specification and Technical Data sheet covers the

Advanced Process Manager only.

For information about APM Input/Output Processors, which

are common to the PM/APM/HPM controller family, please refer

to IO03-500. Process Manager I/O Specification and Technical

Data.

The Advanced Process Manager is designed to provide flexible and

powerful process scanning and control capabilities. To do this, it

uses advanced multi-processor architecture with separate

microprocessors dedicated to perform specific tasks. As depicted in

Figure 3. the APM consists of the Advanced Process Manager Module

(APMM) and the I/O Subsystem.

The Advanced Process Manager Module consists of an Advanced 

Communication Processor and modem, Advanced I/O Link Interface

Processor, and Advanced Control Processor. A redundant APMM can

be optionally provided. The Advanced Communication Processor is

optimized to provide high-performance network communications,

handling such functions as network data access and peer-to-peer 

communications.

It also supports high-accuracy time stamps.

The Advanced Control Processor is the APM resource dedicated to

executing regulatory, logic, and sequence functions, including an

excellent user programming facility. Because communication and

I/O processing are performed by separate dedicated hardware,

the full power of the Advanced Control Processor can be applied

to control strategy implementation. 

The Advanced I/O Link Interface Processor is the APMM interface

to its I/O subsystem.

The I/O Subsystem consists of the redundant I/O Link and up to 40

redundant I/O Processors. These I/O Processors handle all field I/O

for both data acquisition and control functions. For example, the

I/O Processors provide such functions as engineering unit conversion

and alarm limit checking independent of the Advanced Process Manager

Module.

One IOP which illustrates the advanced capabilities of the APM I/O is

the Smart Transmitter Interface. The Smart Transmitter Interface

processor provides full bi directional communication to Honeywell

smart transmitters, supporting transmitter configuration and improved

data accuracy. This includes the recently introduced Multivariable

transmitter capability. All control operations are performed within the

Advanced Process Manager Module (optionally redundant), with all data

acquisition and signal conditioning being performed in I/O Processors.

For added control security, redundancy is available for several

analog and digital I/O processing devices.

The remote I/O option allows I/O Processors to be remote-mounted

up to 8 kilometers from the APM file. This option uses redundant fiber

optic I/O Link extenders.

The process engineer has complete flexibility of choice in the assignment

of point types and control strategies, within the maximum APMM design

limits.

These selections are implemented using the interactive tools provided

by both the TDC 3000X Universal Station and Universal Work Station.

Control Functions

The Advanced Process Manager Module (APMM) provides a variety

of control tools that can be customized to address a wide range of

process automation needs.

Functions, from I/O scanning through regulatory and logic control to

more advanced control, can be easily implemented through the APM.

Included are a sophisticated regulatory control package, fully integrated

interlock logic functions, and an advanced process engineer-oriented

Control Language (CL/APM).

CL/APM is an enhanced version of the Control Language implemented

by Honeywell in the Process Manager. This language facility includes the

sequence structures needed to handle batch or hybrid applications as

well as the computational capability needed
