VII. Сравнение выбора & Варианты замены

1. DP version of the same size: 6AV2123-2MA03-0AX0 (KTP1200 Basic DP)

Equipped with PROFIBUS interface; cannot directly replace this model due to different communication hardware.

2. Upgrade alternative (Comfort Panel): 6AV2124-0MC01-0AX0 TP1200 Comfort

Larger memory, supports scripts and SD card, richer protocols; inconsistent cutout dimensions, cabinet rework required.

3. New-generation Basic Panel alternative: KTP1200 Basic V3 (6AV2123-2MB32-0AW0)

Minimum TIA V17 required; fully compatible mounting dimensions for direct replacement.

VIII. Область применения

Cost-effective solution for small & medium OEM machinery, упаковочное оборудование, очистка воды, ОВК, and small production line control cabinets; suitable for basic monitoring with physical key operation.

1. Common Selection Pitfalls & Примечания
2. No SD card slot, long-term mass data archiving is unavailable. Data can only be exported temporarily via USB; maximum limit for alarms/data logs is 10,000 entries.
3. Resistive touch screen, supports glove operation; multi-touch is not available.
4. Projects programmed for Comfort Panels cannot run directly; projects need recompilation for Basic Panels.
5. Vertical portrait installation is not officially supported; landscape installation recommended only.

Application Scenarios of 6AV2123-2MB03-0AX0 (KTP1200 Basic PN)

Позиционирование продукта: 12-inch basic HMI, resistive touch + physical function keys, PROFINET Ethernet, basic monitoring & операция, экономически эффективный. Limited functionality, no SD card slot.

Compatible PLCs: С7-1200, S7-1500, ET200SP; Modbus TCP enables connection to third-party controllers.

1. Main Mature Industry Applications
2. Упаковочное оборудование (Largest Application Volume)

Vertical/horizontal packaging machines, flow wrappers, sleeve labeling machines, bag-making machines

Case packers, auxiliary palletizing equipment, case sealers, stretch wrapping machines

Преимущества: Physical keys facilitate frequent start/stop operations by operators; 12-inch large screen displays speed, counting values and fault codes intuitively; PROFINET enables fast linkage with S7-1200.

⚠️ Limitation: Not recommended for scenarios requiring continuous long-term production data archiving (no SD card, only temporary USB export available).

2. Plastic Injection & Extrusion Industry

Auxiliary injection equipment: mold temperature controllers, чиллеры, шлифовальные машины, material loaders

Small extruders, pelletizing equipment, pipe haul-off machines

Application characteristics: Cabinet installation under normal workshop temperature & влажность; no complex scripts required; meets demands for temperature monitoring, parameter setting and fault alarm viewing.

3. Очистка воды & Оборудование для защиты окружающей среды

Small integrated wastewater treatment equipment, water reuse systems

Reverse osmosis RO pure water equipment, constant pressure water supply control cabinets, rainwater collection systems

Small waste gas treatment control cabinets (activated carbon adsorption, simple spray towers)

Функции: Multiple analog value monitoring (давление, liquid level, pH, flow rate); supports Modbus TCP connection for transmitters and meters.

4. ОВК & Air Purification Systems

Air handling units, cleanroom air conditioners, constant temperature & humidity control cabinets

Fan variable frequency control cabinets, waste heat recovery units, fresh air systems

Suitable for building auxiliary equipment and small control systems in factory clean workshops.

5. Food Processing Machinery (Non-corrosive Environment)

Small dough mixers, оборудование для выпечки, cleaning lines, сортировочное оборудование

✅ Suitable: Dry ordinary production workshops

❌ Use with caution under high humidity, continuous steam, strong acid/alkali cleaning environments (cabinet moisture-proof reinforcement required)

6. Погрузочно-разгрузочные работы & Conveying Automation (Маленький & Medium Production Lines)

Ленточные конвейеры, roller sorting lines, лифты, small transfer machines

Auxiliary conveying equipment for automated warehouses, small express sorting branch lines

Mostly deployed in fixed factory-mounted complete sets of equipment.

1. Working Conditions Suitable for Selection (Selection Criteria)

✅ Recommended Conditions:

1. The controller is Siemens S7-1200/1500 and PROFINET bus communication is required
2. Large 12-inch display needed; operators prefer dual operation via physical keys and touch
3. Only basic functions required: настройка параметров, equipment start/stop, отображение статуса, fault alarms and simple recipes
4. Uninterrupted long-term data archiving is not required; regular manual USB data export is acceptable
5. Installed inside control cabinet; ambient temperature 0~50°C, no continuous condensation, strong corrosion or violent vibration

❌ Нерекомендуемые сценарии (Selection Warnings)

1. Continuous long-term historical data archiving and long-period curve recording (no SD card slot)
2. HMI built-in web server, OPC UA or complex VBS scripts required (not supported by Basic Panels)
3. High humidity, heavy steam or strong acid/alkali corrosive environments (no enhanced anti-corrosion treatment)
4. Capacitive multi-touch required (this unit uses resistive touch)
5. Legacy systems adopting PROFIBUS DP bus (select DP version 6AV2123-2MA03-0AX0; direct replacement impossible)
6. Vertical portrait mounting (officially only landscape installation allowed)
7. Central monitoring for large production lines (upgrade to Comfort TP1200 recommended)

III. Typical Control Configuration Examples

1. KTP1200 Basic PN + S7-1214C + G120C Inverter → Packaging conveyor line control
2. KTP1200 Basic PN + S7-1215C + Modbus instruments → Integrated water treatment equipment
3. KTP1200 Basic PN + S7-1511C + ET200SP → Automated conveying and sorting stand-alone machine

Configuration Software for 6AV2123-2MB03-0AX0 (KTP1200 Basic PN)

Official software name: Портал ТИА, no standalone program. HMI screen configuration is completed via the built-in WinCC module inside TIA Portal.

1. Supported Software Versions
2. Minimum requirement: TIA Portal V13 SP1 (V13 without SP1 cannot recognize this panel)
3. Compatible versions: V13 SP1, V14, В15, V15.1, V16, V17, V18, V19 (latest release)
4. Valid configuration modules (any one is acceptable)

WinCC Basic (minimum authorization, cost-effective for independent HMI projects)

WinCC Comfort / Передовой / Professional

STEP7 Basic / Professional (integrated with WinCC Basic for combined PLC & Программирование ЧМИ)

1. Critical Restrictions (Frequent Pitfalls)

❌ Classic WinCC flexible (all versions) is NOT supported

WinCC flexible only configures the first-generation Basic Panels and MP series panels; 2nd-generation Basic Panels starting with 6AV2123 are fully incompatible. Do not attempt configuration.

❌ WinCC V7/V8 (PC-based SCADA software) is irrelevant to touch panel configuration.

III. Download Methods

Two available download channels:

1. Ethernet (RJ45 PROFINET) (Primary method)
2. Front USB port + USB flash drive (Backup method for on-site commissioning without network cable)
3. Standard Description for Tender Documents (Direct Copy)

HMI model 6AV2123-2MB03-0AX0 is configured with Siemens TIA Portal Totally Integrated Automation software. Minimum version V13 SP1. Compatible with WinCC Basic/Comfort/Advanced/Professional modules. WinCC flexible is not supported.

1. Practical Selection Advice

HMI configuration only: Install TIA Portal + WinCC Basic

Combined PLC & HMI development (S7-1200/1500): Install STEP7 Basic + WinCC Basi
