Product description

The Siemens Central Processing Unit Module 6ES7-288-1SR60-0AA2 belongs to the standard PLC of the S7-200 SMART series, which is specifically designed for industrial automation control. The following is a detailed description based on the available information:

I. Model Confirmation and Technical Parameters

According to the search results, there may be a clerical error in the model 6ES7-288-1SR60-0AA2 provided by the user. In Siemens' official documents and information from authorized dealers, the standard order number of this module is 6ES7 288-1SR60-0AA0 (discontinued) or 6ES7 288-1SR60-0AA1 (successor model). Its core parameters are as follows:

- **Input and Output Configuration**: 36 channels of 24V DC digital inputs (sink/source type), 24 channels of relay outputs (2A contacts, supporting AC/DC loads).

- **Power Supply Range**: AC 85-264V (47-63Hz) or DC 20.4-28.8V, with a built-in 3A slow-blow fuse.

- **Storage Capacity**: 30KB program memory, 20KB data memory, 10KB retentive memory, supporting the expansion of 6 modules and 1 signal board.

- **Communication Interface**: Integrated with 1 Ethernet port (10/100Mbps) and 1 RS485 serial port, supporting protocols such as PROFINET and Modbus RTU.

- **Performance Characteristics**: The processing speed reaches 0.15μs/instruction, supporting 4 high-speed counters (single-phase 200kHz) and 3-axis linear interpolation (firmware V2.7 and above are required).

II. Compatibility and Software Support

1. **Firmware and Programming Software**:

- **Model 0AA1**: Supports the latest firmware V2.8, and needs to be programmed with STEP 7-Micro/WIN SMART V2.8, adding functions such as override control, motion axis group, and custom Web interface.

- **Model 0AA0**: Only supports firmware V2.5 and below, and cannot be upgraded to the new version. It has been discontinued.

2. **Expansion Modules**:

- Can be connected to digital, analog, communication and other expansion modules (such as EM DR08, EM AE04), with a maximum support of 256-bit input/output.

- The signal board (such as SB CM01) can expand the RS232 or an additional RS485 interface.

III. Price and Supply Status

- **Market Quotation**: Depending on different channels, the price of brand-new genuine products is approximately 760-2000 yuan (domestic in China). For the US market, the quotations of local dealers should be referred to.

- **Supply Situation**: The 0AA0 model has been discontinued, and only spare parts are available; the 0AA1 is the current mainstream model and can be purchased through authorized dealers.

IV. Alternative Models and Upgrade Suggestions

If higher performance or long-term supply is required, the following alternative solutions can be considered:

1. **S7-200 SMART SR60 (0AA1)**:

- It is fully compatible with the 0AA0 model, supports the latest firmware and functions, and is recommended as the priority choice.

2. **S7-1200 Series**:

- Such as CPU 1214C, which supports PROFINET, more communication protocols, and expansion capabilities, and is suitable for complex automation projects.

2. **Genuine Product Verification**:

- The product packaging should have a Siemens anti-counterfeiting label, and the serial number can be verified through the official website or customer service.

VI. Precautions

1. **Firmware Upgrade**: After the 0AA1 model is upgraded, it cannot be downgraded, and the project compatibility needs to be ensured.

2. **Environmental Requirements**: The operating temperature is -20°C to +60°C, and the humidity is 5%-95% (without condensation), which is suitable for industrial environments.

3. **Installation Specifications**: It is recommended to use a CAT5e shielded cable to connect to the Ethernet, and a PROFIBUS network cable for RS485 communication.
