Technical data are based on Siemens' EC31 operating instructions for order number 6ES7677-1DD10-0BA0.
Product Introduction
The Siemens 6ES7677-1DD10-0BA0 is the EC31 embedded controller hardware used in the SIMATIC S7-mEC modular embedded control platform. It combines an Intel Core Duo processor, 1 GB of RAM and integrated flash storage in a compact industrial controller designed to work with the SIMATIC S7 system environment.
Unlike a conventional standalone PLC CPU, the S7-mEC platform combines PC-based computing with S7-300-compatible modular expansion. Depending on the complete order variant, the platform can incorporate additional control software and communication functions. The EC31 hardware identification alone should not be taken as confirmation that a particular software package or licence is included.
Processing and Memory Architecture
The EC31 uses a 1.2 GHz Intel Core Duo processor and 1 GB RAM. Its 4 GB integrated flash memory is partitioned into a 2.5 GB C: drive and a 1.5 GB D: drive. A further 256 KB of non-volatile memory is available for retentive data.
These resources support the controller's embedded operating environment and application execution. The specified operating system is Windows Embedded Standard 2009, while the associated programming interface is the Siemens Software Development Kit for EC31.
Power Supply and Electrical Characteristics
The controller has a nominal 24 V DC supply requirement, with a permitted input range of 20.4–28.8 V DC. Siemens specifies a typical input current of 0.8 A and typical power loss of 20 W; both figures exclude backplane bus and USB supply consumption.
Reverse-polarity protection is provided. The documented power-failure backup time is 5 ms. These ratings are useful when checking the existing cabinet power supply and the electrical requirements of a replacement controller.

System Integration and Expansion
The SIMATIC S7-mEC platform follows the S7-300 modular system concept and can use S7-300 modules, with optional expansion modules available for additional connectivity. Siemens documentation identifies the EM PCI-104 and EM PC as members of the S7-mEC component family.
The EC31 hardware is also used in different complete controller variants, including EC31-RTX and EC31-HMI/RTX versions. These variants can have different preinstalled software and licensing arrangements, so the hardware order number should be distinguished from the order number of a complete configured package.
Operating Environment and Electrical Isolation
Siemens specifies a permitted potential difference relative to the mounting rail of 75 V DC or 60 V AC. Electrical isolation is provided between Ethernet and the electronic circuits.
For industrial use, the documented emissions standard is EN 61000-6-4:2007, and the immunity standard is EN 61000-6-2:2005. Confirm the actual installation conditions and associated system requirements before integrating a replacement unit.
Identification and Variant Selection
The order number 6ES7677-1DD10-0BA0 identifies the EC31 hardware described in Siemens' operating instructions. Siemens notes that EC31 hardware may also be used in configured variants whose complete order numbers differ.
For example, the documentation distinguishes the base EC31 hardware from EC31-RTX F and EC31-HMI/RTX configurations. The latter may include operating software, communication software, runtime software and associated licence materials. Therefore, verify the complete order number and required software configuration before replacing an existing system.

FAQ
What is the Siemens 6ES7677-1DD10-0BA0?
It is the Siemens SIMATIC S7-mEC EC31 embedded controller hardware, featuring an Intel Core Duo 1.2 GHz processor, 1 GB RAM and 4 GB integrated flash memory.
What power supply does the EC31 require?
The rated supply voltage is 24 V DC, with a permitted range of 20.4–28.8 V DC. Its typical input current is 0.8 A, excluding backplane bus and USB supply consumption.
Which operating system does it use?
The EC31 documentation specifies Windows Embedded Standard 2009. Software packages supplied with configured EC31 variants may differ.
Is 6ES7677-1DD10-0BA0 the same as EC31-RTX?
The EC31 hardware is used in EC31-RTX and other configured variants, but the complete product order numbers and software packages differ. Check the existing unit's full order code and software configuration before selecting a replacement.
What memory does the EC31 provide?
It has 1 GB RAM, 4 GB integrated flash memory and 256 KB non-volatile memory for retentive data. The flash storage is divided into 2.5 GB and 1.5 GB partitions.
What should be checked before ordering a replacement?
Verify the complete order number, hardware version, installed software, licensing requirements, connected S7-300 modules and communication configuration. These checks help distinguish the base EC31 hardware from configured variants.
