2. Notes on S7-SCL Programming Language

S7-SCL (Structured Control Language) is a high-level programming language based on PASCAL, which allows structured programming. The language corresponds to the SFC "Sequential Function Chart" language specified in the standard DIN EN-61131-3 (IEC 61131-3). In addition to high-level programming language elements, S7-SCL contains typical elements of the PLC such as inputs, outputs, timers, bit memories, block calls etc. as language elements. It supports the block concept of STEP 7 and allows data blocks to be programmed according to standard as well as using STL, LAD and FBD. In other words, S7-SCL supplements and extends the STEP 7 programming software with its LAD, FBD and STL programming languages.

You do not have to create every function yourself. Instead, you can used already prepared blocks such as system functions or system function blocks that are present in the operating system of the CPU.

Blocks that are programmed with S7-SCL can be mixed with STL, LAD and FBD. This means that a block programmed with S7-SCL can call another block programmed in STL, LAD or FBD. In turn, S7-SCL blocks can also be called in STL, LAD and FBD.

The test functions of S7-SCL allow searching for logical programming errors in an error-free compilation.

3. The S7-SCL Development Environment

To use and deploy S7-SCL there is a development environment that is oriented to specific features of both S7-SCL and STEP 7. This development environment consists of an editor/compiler and a debugger.

Editor / compiler

The S7-SCL editor is a text editor with which texts can be edited. The central task you use the editor for is to create and edit blocks for STEP 7 programs. The syntax of the text you input with the editor is checked thoroughly, making error-free programming simple. Syntax errors are displayed in various colors.

The editor offers the following options:

- Programming a S7 block in the S7-SCL language.

- Convenient insertion of language elements and block calls using drag-and-drop operation.

- Direct syntax check during programming.

- Adjustment of the editor to your requirements by, for example, syntax-oriented coloring of the various language elements.

- Checking of the finished blocks by compiling.

- Display of all errors and warnings that occur during compiling.

- Localizing of the faulty position in the block, optionally with description of error and information on debugging.

Debugger

The S7-SCL debugger provides the option of checking how the program runs in the AS and thus finding any possible errors.

S7-SCL offers two different test modes for this:

- Step-by-step monitoring

- Continuous monitoring

With "Step-by-step monitoring" the logical execution of the program is completed. You can execute the program algorithm instruction for instruction and monitor in a result window how the processed tag contents change during the process.

With "Continuous monitoring" you can test a group of instructions within a block. The values of the tags and parameters are displayed in chronological order during the test run and - where possible - updated cyclically.

4. Example Task Tank Content

4.1 Description of task

Our first program is one to program the calculate the content of tank.

The tank has the shape of an upright cylinder. The fill level of the content is measured by an analog sensor. In the task, the value of the fill level should already existed standardized in the meter unit.

A function FC 140 'calculate_tank content' is to be programmed in the program. The diameter and the fill level in meter unit are the passed parameters. Result is the tank content in the liter unit.

4.2 Assignment list / tag table

Because modern programming uses tags and not absolute addresses, the global PLC tags must be defined here.

These global PLC tags are descriptive names with a comment for each input and output used in the program. The global PLC tags can then be accessed later during programming via their names. These global tags can be used in all blocks anywhere in the program.

Default tag table

SCE_EN_040-020_R1209_Startup Programming in High-Level Languages with S7-SCL and SIMATIC S7-300

Main organization block [OB1]

Block called cyclically by the operating system. Here is the call of the function calculate_tankcontent [FC140]

Function: calculate_tankcontent [FC140]

The actual program is contained in this example. Is called by Main [OB1].

4.3 Program structure

Program execution is written in what are referred to as blocks. The Main [OB1] organization block is provided as default. This block represents the interface to the CPU operating system and is automatically called and cyclically processed by this operating system. From this organization block, additional blocks can be called in turn for structured programming, such as the function calculate_tankcontent [FC140] This function is used to break an overall task down into subtasks. These can then be solved more easily and tested in their functionality.
