ABB AC500 PLC integration in ABB AbilityTM System 800xA

Integration of AC500 PLC into System 800xA

The AC500 PLC hardware can be used for certain

process control functions while the operator

benefits from user experience in System 800xA.

Proven libraries are provided for System 800xA

and AC500. This allows programming control

tasks in the AC500 PLC while System 800xA is the

operator interface. For large distributed projects,

many AC500 PLCs can be connected to a System

800xA node.

Process Control objects

Twelve objects are available which cover the

following functionalities:

• Digital and analog setpoints

• Analog measurement with threshold alarm

functions

• Valve control

• Motor control with or without variable speed

drives

• Proportional integral controller

Communication between System 800xA and

AC500 PLC

Communication between the AC500 function

blocks and the objects in System 800xA uses the

PLC Connect option of System 800xA and the

AC500 OPC Server.

Simplified engineering

The Process Control Objects (PCO) library for

AC500 V2 contains a function block for each

object. The control task is engineered with the

AC500 engineering tool Automation Builder.

The communication between the objects in Sys

tem 800xA and the function blocks in AC500 is

configured with Bulk Data Manager, which is part

of the System 800xA Engineering toolset. A li

brary with ready-made symbols and faceplates

for the objects is available for System 800xA engineering.

Integrated documentation

For engineering, the function blocks for AC500

include the user documentation. The faceplates

provide multi-language support for the text ele

ments and allow adaptation of the color codes of

the elements to the preferences of the application.

Availability

The Process Control Objects Library (PCO) for

AC500 V2 is available in Automation Builder as of

version 2.2.3. The Automation Builder installation

also contains the required OPC server. The corre

sponding 800xA PLC Object Library for 800xA or

Compact HMI can be ordered via the 800xA 6.0.3

add-on features list.
