S7-200 SMART

Use this skill for STEP 7-Micro/WIN SMART V2.8 desktop automation on Windows.

Prefer attaching to an already-open MWSmart session instead of launching the software yourself.

Workflow

1. Run scripts/find_open_200smart_process.ps1 to locate the visible V2.8 window.
2. If the user needs a ready-made case, use the bundled AWL in assets/bag-pulse-dust-collector-4bags-ob1.awl.
3. If writing or editing AWL, keep it LAD-friendly:
   • wrap OB1 logic in ORGANIZATION_BLOCK OB1
   • keep one NETWORK to one rung or action
   • split independent MOV, TON, S, R, and output assignments into separate networks
4. For V2.8, prefer the verified keyboard flow:
   • Ctrl+F1 imports into the active block tab
   • Ctrl+F3 exports the active block tab
   • Ctrl+F6 compiles the project
5. Treat success as a combination of:
   • import or export output contains a success line
   • compile output contains zero errors
   • visible invalid network count is zero when LAD rendering matters
6. Do not save or overwrite the .smart project unless the user explicitly asks.

Verified V2.8 Rules

• Exported block files are plain ANSI/GBK, not UTF-8.
• The active editor tab matters for Ctrl+F1 and Ctrl+F3; tree selection alone is not enough.
• For subroutines, display name mismatches can break callers even when the block number is still SBR15.
• If compile shows a missing-subroutine call and the output lists SBR_15 (SBR15) instead of the expected Chinese block name, reimport a prepared ANSI file whose subroutine display name matches the intended block name.

Reusable Commands

Find the open V2.8 process:

& "$PSScriptRoot\scripts\find_open_200smart_process.ps1"

Capture the current 200SMART window:

& "$PSScriptRoot\scripts\capture_200smart_window.ps1" `
  -OutputPath ".\mwsmart_window.png"

Read the output window:

& "$PSScriptRoot\scripts\read_200smart_output_window.ps1"

Prepare an AWL file for V2.8 import using local ANSI/GBK encoding and an optional subroutine display name:

& "$PSScriptRoot\scripts\prepare_200smart_awl_file.ps1" `
  -SourcePath "C:\path\to\edited.awl" `
  -BlockDisplayName "脉冲气动" `
  -OutputPath "C:\path\to\脉冲气动.awl"

Export the active block with Ctrl+F3:

& "$PSScriptRoot\scripts\export_active_block_200smart_v28.ps1" `
  -OutputPath "C:\path\to\故障报警.awl"

Import the active block with Ctrl+F1 and compile with Ctrl+F6:

& "$PSScriptRoot\scripts\import_active_block_and_compile_200smart_v28.ps1" `
  -AwlPath "C:\path\to\脉冲气动.awl" `
  -ScreenshotPath ".\mwsmart_active_block_compile.png"

Import the bundled OB1 example and compile it:

& "$PSScriptRoot\scripts\import_and_compile_200smart_v28.ps1" `
  -UseBundledBagPulse4 `
  -ScreenshotPath ".\mwsmart_v28_compile.png"

Import a custom OB1 AWL and compile it:

& "$PSScriptRoot\scripts\import_and_compile_200smart_v28.ps1" `
  -AwlPath "C:\path\to\your.awl" `
  -ScreenshotPath ".\mwsmart_v28_compile.png"

Bundled Case

Use the bundled four-bag pulse dust collector example when the user asks for a default working program.

• AWL: assets/bag-pulse-dust-collector-4bags-ob1.awl
• Address and parameter notes: references/bag-pulse-dust-collector-4bags.md

Read When Needed

• For the bundled example logic and addresses, read references/bag-pulse-dust-collector-4bags.md.
• For encoding issues, block-name drift, active-tab import behavior, save prompts, and invalid networks, read references/troubleshooting.md.
