The reference manual provided delivers comprehensive guidelines for programming the SIEMENS SIMATIC S7-300 and S7-400 industrial automation systems using Function Block Diagram (FBD). It is an authoritative document aimed at assisting system programmers and engineers as they create, debug, and maintain control programs for these specific models.
Contents of the Manual
The first sections of the manual provide an overview of different programming instructions categorized by their functionality, indicating the manual’s intent to serve as a robust resource for understanding and applying the FBD language in practical scenarios. This catalogue of instructions encompasses:
- Bit Logic Instructions: Essential commands for performing operations on individual bits.
- Comparison Instructions: Guidelines for comparing values and implementing conditional logic.
- Conversion Instructions: Methods for changing data types or modifying data representation.
- Counter Instructions: Operations related to counting and managing counters.
- Data Block Instructions: Framework for handling and structuring data.
- Jump Instructions: Directives for controlling the sequence of operations.
- Integer Math Instructions: Procedures for performing mathematical calculations with integers.
- Floating-Point Math Instructions: Strategies for employing mathematical functions with floating-point numbers.
- Move Instructions: Descriptions of how to transfer data within the user program.
- Program Control Instructions: Commands for managing the flow of the control program.
- Shift and Rotate Instructions: Techniques for bit manipulation within words or blocks of data.
- Status Bit Instructions: Procedures for accessing and modifying status bits that reflect the state of the program or the process.
- Timer Instructions: Methods for implementing timing functions within programs.
- Word Logic Instructions: Operations for logical processing of data words.
Later sections provide programming examples, demonstrating how to wield these instructions effectively within the context of the S7-300 and S7-400 systems. This pragmatic approach ensures users gain practical knowledge of the instruction set and its applicability.
