Lighting the Way to advancing our

MOD300 DCS

Beginning DCS (Industrial IT)

• AC460 Controllers

• Advabuild for Windows 2000,

Version 3.3

• Operate Process Portal B

The First Upgrade

(System 800xA):

• AC800M Controllers

• Windows XP and Server

2003

• Operate Process Portal A

Process Portal A:

• The Config Server and RTDS’

were replaced with the Aspect

Server and Connectivity Server

• The Graphics changed to VB

Reasoning behind PPA Upgrade:

• End of Lifespan for Servers

• End of Microsoft Support for

Windows 2000

Added First 800M Controller with

Local Operator Screen directly

connected to controller

This Controller was programed in

CBM (Control Builder M)

Advantages to programming in CBM:

• Quick Downloads

• Robust

Disadvantages:

• Hard to see the forest for the trees.

• Faceplates did not match PPA

faceplates

On the Picture Tools | Format

tab, you can create your own

frames and make picture

corrections such as adjusting

contrast and brightness or cropping the picture for just the

right look.

Best Decisions:

• To purchase a Development

System

• Go to thin clients for noncritical

locations.

Things we would do differently and

had to change later:

• Use Explicit Addressing for devices

on the 800xA RNRP control ring

• Not putting AC460 and 800M

controllers on the same ring

Reason to migrate to 800xA Version

5.0 programming:

Advantage of programming in the 800xA

system:

1. No longer constrained by 8 FCM’s to a

loop. In fact, now we can have a loop

(Function Diagram) multiple sheets

deep. This worked well for the control

of VFD’s via Profibus. The typical

mechanics of the data manipulation

was done on sheets 2 and 3, where as

the atypical control was on sheet 1.

Advantage of programming in the

800xA system:

2. You can use logic blocks from

various libraries

3. Easy to integrate Structured Text

programs with Function Diagrams

4. Easy to trouble shoot Function

Diagrams and Structured Text

programs

Advantage of programming in the

800xA system:

5. Logic organized in a tree structure

Advantage of programming in the

800xA system:

5. SFC language is available.

Our last upgrade

(System 800xA version 5.1):

• Windows 7 and Server 2008

R2

• Replaced obsolescent

servers with four VMWare

Servers
