The 6ES7621-1AD01-0AE3 (6ES76211AD010AE3) is a highly integrated, "all-in-one" automation controller that merges a SIMATIC S7-300 PLC with an OP 3 operator panel. Designed with a footprint similar to the C7-633/634 and OP7/17 series, this compact unit is engineered for machine-level control where cabinet space is limited. It provides a complete control loop solution out of the box, featuring built-in digital and analog I/O alongside an IM 621 interface module for expansion. This hardware is a staple in legacy manufacturing cells, offering a unified platform for logic processing and human-machine interface (HMI).
| Feature | Technical Data |
| Manufacturer | Siemens |
| Model Number | 6ES7621-1AD01-0AE3 |
| Integrated CPU | SIMATIC S7-300 Technology |
| Integrated HMI | OP 3 Operator Panel |
| Digital Inputs (DI) | 16 Channels (24V DC) |
| Digital Outputs (DO) | 16 Channels (24V DC / 0.5A) |
| Analog Inputs (AI) | 4 Channels |
| Analog Output (AO) | 1 Channel |
| Interface Module | Integrated IM 621 |
| Dimensions (W x H x D) | 178 mm x 102 mm x 127 mm |
| Net Weight | 0.90 kg (Approx. 1.98 lbs) |
| Product Phase | Obsolete (Replaced by 6ES7621-1AD02-0AE3) |
| ECCN Regulation | N (Non-restricted) |
The 6ES7621-1AD01-0AE3 excels in standalone machine automation. By consolidating the processor, the display, and a versatile I/O mix (including analog for temperature or pressure sensors), it significantly reduces wiring complexity and potential points of failure. The integrated IM 621 allows the unit to link with additional S7-300 expansion racks if the onboard I/O count is exceeded. Despite its "Obsolete" status, it remains a critical spare part for maintaining older production lines that rely on the specific physical mounting and communication protocols of the S7-621 range.
Is the 6ES7621-1AD01-0AE3 directly interchangeable with its successor?
The 6ES7621-1AD02-0AE3 is the official successor. While it is functionally compatible, you should verify the firmware versions and memory requirements of your existing STEP 7 project before performing a direct swap.
How is the integrated OP 3 panel programmed?
The HMI portion is typically configured using Siemens ProTool or WinCC Flexible. The PLC logic is handled via standard STEP 7 (V5.x). Communication between the CPU and the internal OP 3 is handled via an internal bus, requiring no external MPI cabling for basic operation.
