Product Description

The 6ES7621-1AD00-6AE3 belongs to the SIMATIC C7-621 series. It is a specialized “all-in-one” control system that integrates a SIMATIC S7-300 CPU 312IFM with an OP3 Operator Panel into a single, compact unit. This product is designed for small machines where space is at a premium and a combined control/HMI solution is required.

Product Parameters

Key Product Advantages

• Space Saving: By combining the PLC and the HMI into one housing, the C7-621 significantly reduces the footprint required in the control cabinet.

• Integrated I/O: Comes with built-in digital inputs and outputs, allowing it to handle simple machine tasks immediately without adding extra I/O modules.

• Seamless Integration: Because the internal PLC is an S7-300, it uses the same programming environment (STEP 7), making it familiar to Siemens developers.

• Cost-Effective: Purchasing a single C7 unit is often more economical than buying a separate CPU, I/O modules, and an Operator Panel.

Critical Usage Notes & Precautions

1. Limited Memory: With only 6 KB of work memory, this unit is intended for small-scale logic. It is not suitable for complex data processing or large-scale automation.

2. Product Lifecycle: The C7-621 series is a legacy product and has been largely replaced by the SIMATIC Comfort Panels or Basic Controllers (S7-1200). Availability of spare parts may be limited or require refurbished units.

3. Programming Cable: You will need a PC Adapter or an MPI cable to download programs to the unit via the 9-pin MPI port.

4. HMI Configuration: The integrated OP3 panel is configured using ProTool or older versions of WinCC Flexible.

Product Applications

The C7-621 is typically found in standalone, compact machinery:

• Small Packaging Machines: Controlling simple filling, sealing, or labeling processes where the operator needs to enter basic parameters (like counts or timers).

• Pumping Stations: Monitoring pressure levels and controlling motor starters in local water distribution.

• HVAC Control: Managing ventilation fans and heating elements in commercial buildings.

• Laboratory Equipment: Automating simple test sequences and displaying status messages.
