G1 Introduction to AC500 1-20 AC500 / Issued: 07.2006
With embedded digital I/Os and a field-bus-neutral interface for connecting the chosen FBP connector.
For decentralized expansion by up to seven I/O modules.
The SD card
The SD memory card is used for the following purposes: Backup of user data, storage of the user
program, storage of the project’s source code, update of the internal CPU firmware.
Short description of the software
Programming in conformity with IEC 61131-3
AC500 Control Builder provides the following functionalities:
■ Five standardized programming languages: Function Block Diagram (FBD), Instruction List (IL),
Ladder Diagram (LD), Structured Text (ST), Sequential Function Chart (SFC)
■ Free graphical function chart (CFC)
■ Debugging functions for the program test: Single step, Single cycle, Breakpoint
Offline simulation
IEC 61131-3 commands can be simulated without a PLC being connected, including the relevant
malfunctions. After the program test, the application can be downloaded to the control system.
Sampling trace
Timing diagrams for process variables and storage of data in a ring buffer with event trigger.
Recipe management and watch lists
Values of selected variables are displayed. Pre-defined values can be assigned to variables which can
then be downloaded to the control system all at once (“Write recipe”). Ongoing values from the control
