Sélection & On-site Replacement Cautions

1. Large stock available on second-hand market. Clearly distinguish 0BC11 (No USB) / 0CC11 (With USB); programs cannot be directly interchanged.
2. If the original project is `.hmi` file developed with WinCC flexible 2008, program migration is mandatory when replacing with V3 touchscreen.
3. Communication Cable: Use standard PPI cable for S7-200; shielded RS485 cable for third-party PLCs.
4. 0BC11 has no USB function; program download is only available via Ethernet or serial port.

I can provide the following materials on request:

COM port pin assignment definition;

Step-by-step wiring & configuration for communication with S7-200 / S7-200 SMART;

Complete project migration procedure between old and new panels.

Complete Project Migration Procedure:

6AV6648-0BC11-3AX0 (INTELLIGENT 700 IE V2) → 6AV6648-0CC11-3AX0 (INTELLIGENT 700 IE V3)

Prerequisite Notice:

Two types of program source from old HMI:

① Original `.hmi` project file (Recommended method)

② Only backup file `.psb` uploaded from touchscreen → Cannot be edited or migrated, can only be downloaded back to V2 touchscreen of the same model!

⚠️ Without original `.hmi` project file, migration to V3 is impossible; full re-configuration is required.

1. Préparations

1.1 Environnement logiciel

Option A (Most Stable): WinCC flexible SMART V3 / V3 SP2 (Supports direct opening of V2 projects created by WinCC flexible 2008 SP4)

Option B: Open legacy project with WinCC flexible 2008 SP4 China for preprocessing, then open in SMART V3

❌ Do NOT use WinCC flexible SMART V4/V5 for conversion; high risk of compatibility failure. V3 is the designated migration software.

1.2 File Backup (Obligatoire)

1. Make a separate copy of original `.hmi` project to prevent file corruption during conversion;
2. Store project under pure English path, avoid Chinese characters, spaces and special symbols;
3. Record original communication parameters: HMI IP address, PLC station address, protocole de communication (S7/Modbus RTU).
4. Standard Migration Steps (With Original .hmi Project)

Étape 1: Open Legacy Project

Launch WinCC flexible SMART V3

【File】→【Open】, select legacy `.hmi` project created by WinCC flexible 2008 SP4

Software will pop up project conversion prompt, click【OK】to start automatic conversion.

If conversion fails:

Open project in WinCC flexible 2008 SP4 →【Project】→【Archive】to generate `.cab` archive file;

Back to SMART V3 →【Project】→【Unarchive】and select the `.cab` file to open.

Étape 2: Change HMI Device Type (Core Operation)

1. In project tree on left side, right-click【Device_1 (INTELLIGENT 700 IE)】→【Change Device Type】
2. Select target model:

SIMATIC HMI SMART 700 IE V3 | 6AV6648-0CC11-3AX0

3. Confirm modification. Resolution keeps 800×480 consistent, no screen stretching.

Étape 3: Full Rebuild & Compilation, Troubleshoot Errors

Menu:【Project】→【Compiler】→【Rebuild All】

Resolve errors and warnings one by one:

1. VBS script syntax errors: Partial legacy VBS functions supported by V2 are incompatible with V3. Focus on cyclic screen scripts, button scripts;
2. Missing fonts: Replace custom fonts with SimSun / Microsoft YaHei;
3. Third-party drivers (Modbus RTU): Drivers are fully compatible in most cases, aucune modification nécessaire;

Warnings can be accepted after verification; All errors must be eliminated before downloading!

Étape 4: Verify Communication Parameters

Open【Connections】to check PLC communication links:

S7-200 SMART Ethernet: Parameters remain unchanged;

RS485 Modbus RTU / PPI: Serial parameters keep consistent;

V2 and V3 share identical COM pin definition, wiring does not need adjustment.

Étape 5: Download Project to New V3 HMI

1. Power on touchscreen and enter【Transfer】mode;
2. Set PC IP in the same network segment as HMI;

3.【Project】→【Transfer】→【Transfer】

Optional tick boxes:

✅ Overwrite recipe data logs (As required)

✅ Overwrite user administration

V3 HMI supports USB download; exported project can be transferred via USB flash drive.

3. Différences clés & Notes de mise en service
4. Hardware Interface Difference

V2 (0BC11): No USB Host; V3 (0CC11): Built-in USB port. USB data logging function works only if configured in project; no adjustment needed for existing projects without USB functions.

2. Cutout Dimension

Cabinet cutout 192×138 mm for both models, aucune modification de l'armoire n'est requise.

3. Firmware Matching

Recommended firmware V3.0 or above for new V3 touchscreen. Software will match OS version automatically during download; follow prompt to update HMI OS if required. Do NOT cut off power during OS update.

4. Défauts courants & Solutions

Faute 1: SMART V3 fails to open 2008 SP4 project, conversion aborted

Solutions:

1. Move project to pure English directory;
2. Open project in WinCC flexible 2008 SP4 →【Project】→【Archive】;
3. Use【Unarchive】function in SMART V3 to load the `.cab` file.

Faute 2: Massive object errors after changing device type

Solutions:

Run Rebuild All; If severe incompatibility occurs, create blank SMART700 IE V3 project, copy screens one by one to avoid global conversion bugs.

Faute 3: Only `.psb` backup file uploaded from old touchscreen

❗ Migration Not Possible!

`.psb` is encrypted HMI image file, only restorable to original V2 touchscreen, cannot be edited or assigned to another device model.

Solutions: Retrieve original `.hmi` project or redevelop the whole project.

5. Standard On-site Replacement Procedure (Machine Shutdown)
6. Stop equipment, export recipes from old HMI if important process parameters exist;
7. Éteindre, remove old touchscreen and install new V3 unit;
8. Complete wiring: 24V power, Ethernet, RS485 (pin assignment unchanged);
9. Download migrated project;
10. Verify communication, boutons, alarms and data display;
11. Import backed-up recipes, carry out no-load trial operation.

Summary of Potential Migration Failures: INTELLIGENT 700 IE V2(0BC11) → V3(0CC11)

1. Source File & Project Issues (Le plus courant)
2. No original `.hmi` project, only `.psb` uploaded backup

`.psb` is encrypted mirror backup, can only be restored to same-model V2 HMI. No editing, no model conversion, cannot migrate to V3.

Many field engineers mistakenly believe uploaded `.psb` can be converted, this is the most frequent misunderstanding.

2. Project path contains Chinese characters, spaces or special symbols

The conversion engine of WinCC flexible SMART V3 has poor compatibility with non-English paths, resulting in conversion termination or failure to open project.

3. Legacy project file damaged without archiving repair

Long-term repeated editing or unexpected shutdown leads to internal project file corruption.

Phénomène: Direct opening in V3 fails. Workaround: Archive project to `.cab` in WinCC flexible 2008 SP4 then unarchive in V3.

4. Excessive project version gap

Project originally created in WinCC flexible 2008 SP2/SP3 without upgrading to SP4. Conversion error is highly likely if imported directly into SMART V3.

2. Environnement logiciel & Version Mismatch
3. Using WinCC flexible SMART V4/V5 for conversion

V4/V5 removes native conversion interface for WinCC flexible 2008 SP4 V2 projects. Not applicable for migration, may cause missing scripts and incomplete conversion.

Recommended migration software: WinCC flexible SMART V3 / V3 SP2.

2. Incomplete software installation, missing drivers/patches

Antivirus blocks components during setup; simplified/cracked software lacks conversion modules, leading to sudden crash during conversion.

✅ Requirement: Official complete installation package, disable antivirus before installation.

3. Insufficient Windows system permission

Software not launched with【Run as administrator】. Windows blocks temporary file access, conversion terminates midway.

3. Internal Project Compatibility Conflicts

(Project can be opened, but heavy compilation errors after device type change)

1. VBS Script Compatibility Gap

Some legacy VBS functions supported under WinCC flexible 2008 (V2) are deprecated in SMART V3 runtime library.

Cyclic screen scripts, button scripts and alarm scripts are most vulnerable; extensive global scripts may disable device type modification.

2. Incompatible third-party communication drivers

Early customized Modbus RTU configuration or obsolete PLC drivers may be lost after conversion, communication connection parameters invalidated.

3. Missing custom fonts

Project uses non-system fonts; text controls abnormal, screen objects fail to load, even compilation crash.

4. Complex configuration of recipes, data logs and user rights

Recipe layout and archive path format of V2 are different from V3, triggering recipe component errors after conversion.

5. Screen controls & ActiveX components

Third-party ActiveX controls embedded in project are no longer supported by SMART V3. Controls disappear during conversion and cause project loading failure.

4. Specific Errors When Changing Device Type
5. Project opened successfully, but【Change Device Type】is greyed out

Raison: Incompatible objects detected (invalid scripts, broken controls, illegal variables), software locks device modification function.

Solution: Clear all errors first, or create blank V3 project and copy screens individually.

2. Incorrect panel model selected

Accidentally select SMART 700 IE (non-V3) or KTP700 Basic, model mismatch leads to compilation error.

Correct target: `SIMATIC HMI SMART 700 IE V3 6AV6648-0CC11-3AX0`

5. Download-stage Faults after Successful Conversion

(Project conversion completed, cannot download to new HMI)

1. Outdated HMI firmware

Old V3 firmware does not support migrated project. OS update required when prompted.

2. Incorrect IP segment or transfer mode setting (Not conversion error, often confused as migration failure).
3. Download attempted with unresolved compilation Errors

Warnings can be evaluated; All Error items must be cleared, otherwise project cannot be loaded into HMI.

6. Human Operation Mistakes
7. Forget to execute【Change Device Type】after opening project, directly download V2 project to V3 HMI → Error prompt: Device model mismatch.
8. Run multiple configuration software simultaneously (WinCC flexible 2008 SP4 + SMART V3), process conflict causes conversion anomaly.

Tiered Rapid Troubleshooting Flow

1. Confirm file type: Original `.hmi` or uploaded `.psb`? → `.psb` = Migration impossible
2. Move project to pure English path, launch SMART V3 SP2 as administrator
3. Archive project to `.cab` within WinCC flexible 2008 SP4, open project via【Unarchive】in V3
4. Rebuild all and count errors; adopt “copy screens to blank project” method if script/control incompatibility is severe
5. Recompile fully after successful device type change, eliminate all Error items
