PLC Coder: General

PLC Coder: General Tab Overview

Set up general information about generating Structured Text code to download to target PLC IDEs.

Configuration

To enable the Simulink® PLC Coder™ options pane, you must:

  1. Create a model.

  2. Add either an Atomic Subsystem block, or a Subsystem block for which you have selected the Treat as atomic unit check box.

  3. Right-click the subsystem block and select PLC Code > Options.

Tip

  • In addition to configuring parameters for the Simulink PLC Coder model, you can also use this dialog box to generate Structured Text code and test bench code for the Subsystem block.

  • Certain options are target-specific and are displayed based on the selection for Target IDE.

Tips

  • Rockwell Automation RSLogix 5000 routines represent the model hierarchy using hierarchical user-defined types (UDTs). UDT types preserve model hierarchy in the generated code.

  • The coder generates code for reusable subsystems as separate routine instances. These subsystems access instance data in program tag fields.

Tips

  • When you change the Target IDE value, the value of this parameter changes.

  • If you right-click the Subsystem block, the PLC Code > Generate and Import Code for Subsystem command uses this value to import generated code.

  • If your target IDE installation is standard, do not edit this parameter. Leave it as the default value.

  • If your target IDE installation is nonstandard, edit this value to specify the actual installation path.

  • If you change the path and click Apply, the changed path remains for that target IDE for other models and between MATLAB® sessions. To reinstate the factory default, use the command:

    plccoderpref('plctargetidepaths','default')

Command-Line Information

See plccoderpref.

Settings

Default: plcsrc subfolder in your working folder

Command-Line Information

Tips

  • If the target folder path is empty, a default value of ./plcsrc is used as the Code Output Directory.

  • If, you want to generate code in the current folder use . as the output directory.

  • The Code Output Directory can have the same name as your current working folder.

Generate Functions Instead of Function Block

Use this option to control whether the generated Structured Text code contains Function instead of Function Block. This option is available for only the Phoenix Contact PC WORX or the PHOENIX CONTACT (previously KW) Software MULTIPROG target. There are certain cases where you may not be able to generate code with Function instead of Function Block. For example, if your Simulink subsystem or MATLAB Function block has internal state or persistent variables. In such cases, the software issues a diagnostic warning.

This option is available on the PLC Code Generation pane in the Configuration Parameters dialog box, when the Target IDE is set to Phoenix Contact PC WORX 6.0 or KW-Software MULTIPROG 5.0.

Settings

Default: off

On

The generated Structured Text code contains Function instead of Function Block where possible.

Off

Switch to the default behavior of the software.

Command-Line Information

Parameter: PLC_EmitAsPureFunctions
Type: string
Value: 'on' | 'off'
Default: 'off'

Allow Functions with Zero Inputs

Emit a function with no inputs as a function instead of a function block. This option is available for only the Phoenix Contact PC WORX or the PHOENIX CONTACT (previously KW) Software MULTIPROG target.

When the Target IDE is set to Phoenix Contact PC WORX 6.0 or KW-Software MULTIPROG 5.0, in the Configuration parameters dialog box, PLC Code Generation pane, this option is available.

Settings

Default: off

On

Aggressively Inline Structured Text Function Calls

Using this option, you can control inlining of Structured Text function calls for Rockwell Automation targets. By default, the software attempts to inline only math functions where possible. With this option, the software aggressively inlines all function calls so that the generated code has less number of Function blocks.

This option is available on the PLC Code Generation pane in the Configuration Parameters dialog box, when the Target IDE is set to Rockwell Automation targets such as Rockwell Studio 5000: AOI, Rockwell Studio 5000: Routine, Rockwell RSLogix 5000: AOI, or Rockwell RSLogix 5000: Routine.

Settings

Default: off

On

Aggressively inlines Structured Text function calls for RSLogix IDE.

Off

Reverts to its default behavior and inlines only math function calls in the generated code.

Command-Line Information

Parameter:PLC_EnableAggressiveInlining
Type: string
Value: 'on' | 'off'
Default: 'off'
