Features:
- 6ES7636-2EC00-0AE3 combines a CPU 315-2 DP, an OP270B key panel, and integrated mixed I/O in one compact unit.
- A 5.7-inch 256-color display and 24 function keys form the local operator interface.
- Separate MPI and PROFIBUS DP interfaces divide programming and S7 communication from distributed I/O traffic.
The CPU side of Siemens 6ES7636-2EC00-0AE3 executes the automation program while the OP270B side presents process information and accepts local key commands.
Its 24 digital inputs, 16 digital outputs, five analog inputs, and two analog outputs connect 6ES7636-2EC00-0AE3 directly to field signals before external expansion is added.
A Micro Memory Card holds the CPU load program, and the required connector set completes the physical I/O boundary for 6ES7636-2EC00-0AE3.
The Siemens 6ES7636-2EC00-0AE3 SIMATIC C7-636 Key Compact Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

How the CPU and Operator Panel Share the Compact Unit
- CPU role: The CPU 315-2 DP executes the S7 program and handles integrated and expanded I/O
- Panel role: The OP270B display and function keys present process views and accept local commands
- Physical integration: Control and operator functions occupy one enclosure while retaining separate tasks
- Required media: A Micro Memory Card stores the CPU load program, and the connector set completes the field-wiring interface
How Integrated Field Signals Reach the Controller
- Digital acquisition: Twenty-four digital inputs collect 24 V DC field states, including sixteen channels assigned to technology functions
- Digital actuation: Sixteen digital outputs switch connected loads, with four channels available as high-speed outputs
- Analog measurement: Four inputs accept voltage or current signals while a fifth input is reserved for resistance or RTD measurement
- Analog command: Two analog outputs provide configured voltage or current signals to external equipment
- Range agreement: The selected signal range in the project must match the wiring and field-device type used on each analog channel
From Integrated I/O to a Four-Rack Arrangement
- Direct attachment: The compact unit accepts up to two expansion modules in a flat arrangement or four in a deep arrangement
- Rack structure: The documented configuration can extend to four racks
- System total: Up to twenty-three modules can be included across the complete arrangement
- Project agreement: STEP 7 hardware order and addressing must follow the physical module sequence so each signal retains its assigned address
Separate MPI and PROFIBUS DP Paths
- MPI path: The integrated non-isolated RS-485 interface supports programming devices, operator devices, S7 communication, routing, and global-data exchange at up to 187.5 kbit/s
- DP path: The isolated RS-485 PROFIBUS interface can operate as a DP master or slave at up to 12 Mbit/s
- Master boundary: As a DP master, 6ES7636-2EC00-0AE3 supports as many as 125 slaves
- Master data areas: The DP master interface provides up to 244 bytes of input data and 244 bytes of output data
- Slave transfer area: DP slave operation provides up to 244 bytes for each transfer direction
