Features:
- Integrates touch visualization and CPU 314C-2 DP control in one panel unit.
- Handles local analog and digital field signals through onboard I/O.
- Extends the control project through an integrated PROFIBUS DP interface.
The C7-635 Touch replaces a separate controller-and-panel arrangement with a common enclosure and shared power connection.
Operators work through the resistive display, while two fixed membrane keys remain available for functions assigned by the panel project.
A required Micro Memory Card carries the CPU project, and the connector set establishes the boundary between the internal channels and field wiring.
The Siemens 6ES7635-2EB02-0AE3 C7-635 Touch Compact Control Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Interacting with the process display
- Resistive layer: Screen objects respond to pressure applied at the configured touch area.
- Graphic area: The 320×240 display presents process screens across a 116×87mm active field.
- Blue levels: Four display shades separate graphic elements and operating states.
- Fixed keys: Two membrane keys supplement the touch objects with assigned panel functions.
Connecting the integrated process points
- Binary sensing: Twenty-four digital inputs receive local on-off field conditions.
- Load commands: Sixteen digital outputs switch the programmed local actuators.
- Measured values: Five analog inputs acquire the configured continuous signals.
- Continuous outputs: Two analog outputs send calculated command values to field devices.
Transferring control and panel projects
- CPU storage: The controller configuration requires a SIMATIC Micro Memory Card.
- Panel content: Windows CE hosts the TP 170B runtime used for the configured visualization.
- Memory version: The 02 order-number position identifies the 96 KB working-memory version.
- Retention: Up to 64 KB is available for data configured as retentive.
Extending beyond the onboard channels
- Integrated master: The CPU 314C-2 DP communicates with configured PROFIBUS stations.
- Address mapping: Distributed inputs and outputs are assigned alongside local addresses in the CPU project.
- Network setup: Bus address and transmission parameters must match every station on the segment.
- Combined view: The user program can process local and DP data within the same cyclic logic.
