Features:
- Runs EC31 SDK applications on an embedded Intel processor.
- Connects modular S7-300 I/O through the integrated backplane bus.
- Separates PROFINET, Industrial Ethernet, USB, and memory-card interfaces.
The EC31 places PC-based processing and a SIMATIC backplane interface in one rail-mounted controller.
Its flash partitions store the operating environment and application files, while dedicated non-volatile memory holds retentive values.
Local I/O expansion and network communication follow different physical paths, allowing the backplane and Ethernet ports to be planned independently.
The Siemens 6ES7677-1DD10-0BA0 EC31 S7 Modular Embedded Controller may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Dividing network and peripheral access
- PROFINET pair: Two ports provide the controller’s PROFINET connection.
- Industrial Ethernet: A separate Ethernet interface handles the additional network path.
- USB pair: Two USB ports connect supported peripheral devices.
- Card slot: The SIMATIC Micro Memory Card interface accepts the specified removable medium.
Organizing system and retained data
- RAM: One gigabyte provides working memory for the embedded controller.
- C partition: The integrated flash assigns 2.5 GB to drive C.
- D partition: A further 1.5 GB is assigned to drive D.
- Retentive area: A separate 256 KB non-volatile region stores designated retained data.
Extending the local controller
- Backplane bus: S7-300 modules connect behind the EC31 through the SIMATIC bus.
- Module sequence: The hardware arrangement defines which expansion module occupies each position.
- Power demand: Backplane loads are added to the controller’s own supply current.
- Local path: I/O exchange over the backplane does not use the external Ethernet connectors.
Keeping the EC31 software environment available
- Embedded system: Windows Embedded Standard 2009 is installed on the integrated flash disk.
- SDK interface: EC31 applications use the supplied software-development interface.
- Restore media: The controller package includes media for restoring the documented software image.
- Card handling: The SIMATIC Micro Memory Card must be treated as EC31 media because its S7 format is overwritten.
