Honeywell TDC 3000X Advanced Process Manager

Introduction

The Advanced Process Manager (APM) is Honeywell’s most popular

and well established TDC3000 data acquisition and control device

for industrial process applications.

Like the Process Manager™ (PM), its predecessor, and the High

Performance Process Manager (HPM), its successor, the APM

offers a range of capabilities that meets today’s and tomorrow’s

process requirements. The APM offers highly flexible I/O functions

for both data monitoring and control. Powerful control functions,

including regulatory, logic, and sequencing control are provided

for continuous, batch, or hybrid applications.

An optimal toolbox of functions that can be configured and

programmed meets the needs of data acquisition and advanced

control requirements in a highly secure nd performance-intensive

manner. Of course, APM’s capabilities include peer-to-peer

communications and compatibility with industry-standard

communications protocols.

As shown in Figure 2. the APM is a fully integrated member of the

TDC 3000X family. Accordingly, it is capable of:

• Performing data acquisition and control functions, including

regulatory, logic, and sequential control functions, as well as

peer-to-peer communications with other Universal Control

Network-resident devices.

• Providing bi-directional communications to Modbus™ and

Allen-Bradley compatible subsystems through a serial interface.

• Fully communicating with operators and engineers at Universal

Stations, UXSs, and Universal Work Stations.

Procedures and displays are identical or similar to those used

with other TDC 3000X controllers, as well as to HPMand PM

point displays.

• Supporting higher level control strategies available on the Local

Control Network through the Application Module and host

computers.

• Using the same I/O and wiring as the PM and HPM, thus providing

cost-effective upward migration from existing PMs as well as the

capability to migrate to HPMs in the future.

Universal Control Network The communications channel for the

Advanced Process Manager is a local area network called the

Universal Control Network (UCN).

Introduced to TDC 3000X users in 1988. the UCN is the secure

path for process I/O connections to the TDC 3000X.

The UCN features a 5 megabit per second, carrier band communica

tion system with a token bus network. It is designed to be

compatible with IEEE* and ISO** standards.

consistent with the growth and direction of evolving international

standards, with appropriate Honeywell extensions for secure

process control applications.

The UCN uses redundant coaxial cables and can support up to 32

redundant devices. The UCN supports peer-to-peer communication

between devices on this network. This feature enables sharing

information among HPMs, APMs, PMs, Safety Managers, and Logic

Managers on the network, thus offering tremendous power and

flexibility in implementing advanced, coordinated control strategies.

Network Interface Module The Network Interface Module (NIM)

provides the link between the Local Control Network and the 

Universal Control Network.

Accordingly, it makes the transition from the transmission technique

and protocol of the Local Control Network to the transmission

technique and protocol of the Universal Control Network. The NIM

provides LCN module access to data from UCN-resident devices.

It supports program and database loads to the Advanced Process

Manager and forwards alarms and messages from the network

devices to the LCN. The NIM is also available in a redundant

configuration to provide automatic, continued operation in the event

of a primary failure.

LCN time and UCN time are synchronized by the NIM. The NIM

broadcasts LCN time over the UCN. The APM (as well as the HPM)

uses it for a number of time driven functions, such as sequence

of events reporting.
