Sample Course: Basic NETWORK/INFI 90 Training Course

Provided by Integral Control System Services, Inc.

DAYS 1 and 2

System Overview

All students report to the main office conference room. A thorough Network 90 distributed control system overview will be given by ICSS, Inc. Specific topics and system components to be introduced will include the following:

Review specific items more thoroughly based on student input.


Instruction will be provided on the Bailey Plantloop system data highway. Information will include node-to-node communication scheme, system redundancy, Bailey exception reporting, communications technique, and specific nodes in service at Customer.

ICSS, Inc. will provide instruction on the Bailey Process Control Unit (PCU). A complete breakdown of a process control unit will be conducted. The types of system and I/O power supplies used by Customer will be discussed. The intelligent and I/O slave modules used for the boiler controls will be addressed. A top-to-bottom approach to PCU's utilized at the Customer facility will be taken.

A Process Control Unit cabinet arrangement drawing will be covered in great detail. At the completion of this field exercise, the students will be able to identify specific components and their respective locations in a PCU enclosure.

The entire path of specific field device inputs and system output signals will be traced to show the students how a system variable is measured and routed through the Bailey Network 90-Infi 90 distributed control system. The path starting from a field transmitter to the operator interface station and back will be thoroughly investigated. Each piece of transport medium (electrical) will be pointed out. This will be performed for both analog and digital control signals.

Switch settings, jumpers, cables, termination units, and the set-up of each I/O module in the Customer system will be thoroughly discussed.

A portion of the actual Boiler Combustion Control System drawings will be handed out to each student as a training aide. At the completion of this exercise, the students will be able to read and understand the Bailey module configuration drawings as they apply to the Customer facility.

The students will be exposed to the Bailey Function block library at this time. The handout will be discussed block-by-block to provide the students with a thorough understanding of the control system application.


Detailed training will be provided on the use of the Bailey Windows-based Module Configuration Tools. At the completion of this exercise, the students will be able to locate, access and manipulate system configuration drawings for engineering and maintenance purposes. Specific topics to be introduced are the following:

Customer's Computer Interface Unit will be discussed by ICSS, Inc. At the completion of this task, the students will be familiar with the computer interface unit and their respective locations at the Customer facility.

In-depth training will be given on the use of the inspection, maintenance and file loading utilities for the Bailey Network 90 and Infi 90 System. At the completion of this exercise, the students will be able to inspect modules, verify configurations, upload and download module configuration files, and perform live trending and tuning functions from the engineering workstation.


Upon completion of this session, the students will be able to recognize and correct various system anomalies, perform power system checks, adjustments, and complete Network 90 and Infi 90 system preventive maintenance tasks.

Training will be provided on the operator console, Process Portal B, regarding the operation of the system. The various types of controllable system function blocks will be presented, along with how each one is represented on the console and how to manipulate the control-type elements. A walk-through of the system will be conducted on the operator interface station to familiarize the students with the system application.

Areas to be covered are:

The Engineering Workstation (EWS) will be covered. An explanation of the EWS tools will be given. The Bailey Widows-based CAD and console developmental tools will be examined. The students will be instructed on how to back up the entire control system on the Engineering Work Station. Loading, backing-up, and verifying module configuration will be covered.

As with all training courses provided by ICSS Inc., students are welcome to ask questions or exchange ideas freely throughout the entire session.

The Engineering Work Station (EWS) and the Process Portal B console are devices that normally require a minimum of one week of training each. We will be providing basic training on these devices, as defined herein, which will give the trainees a good understanding of the equipment, and the necessary knowledge to utilize the equipment as tools in some cases, to better support their maintenance and troubleshooting efforts. To this end, some topics may be covered more in depth than others, to better meet the needs and knowledge levels of the students.

Q&A session and review and/or a more in depth explanation of previous material.
