The PLC Control Builder

Programmable Logic Controller (PLC) Control Builder is a tool of programming for building PLC based control solutions when the PLC hardware is using the AC 800M hardware. The PLC Control Builder presents with solutions type for loop control, alarm handling simple logic control, device control, etc. packaged as standard libraries. The Control Builder chains five programming languages, Instruction List (IL), Ladder Diagram (LD), Function Block Diagram (FBD), Sequential Function Chart (SFC), and Structured Text (ST) according to IEC 61131-3. The additional to this chains the language of Control Module. The other functionality of Control Builder is for online debugger and test mode.

The core user interface of Programmable Logic Controller (PLC) Control Builder is called Project Explorer and this is where you build and make your projects. A project consist the entire configuration required for a PLC based control solution, including hardware settings and control applications. Context menus are accommodating while linking parameters or configuring hardware units etc. click the right button of mouse on an object to open its matching context menu. Both the software and the hardware are modeled in a project.

It is transferred with a wide-ranging set of predefined type solutions saved in standard libraries. These include function blocks, data types, functions, and Control Modules that can be used in your projects. All standard libraries are incorporated during the PLC Control Builder setting up and are obtainable in your projects. PLC Control Builder gives the following libraries:
• The Basic library, consists blocks of basic building for control software of AC 800M like function block types, data types, and control module types with extensive functionality, that designed by ABB.
• The Communication Libraries contain function blocks for Foundation Fieldbus, SattBus, MMS, Siemens 3964R, and ModBusCOMLI protocols.
• The Control Libraries contain cascade PID control and single PID control function blocks, control modules, etc.
• The Alarm and Event Library, it includes function blocks for alarm printouts on a local printer, alarm and event detection.
