Features:
- Standard PC interfaces extend the S7 modular Embedded Controller assembly.
- CompactFlash and SD/MMC slots separate the two removable-media paths.
- ON and CARD indicators distinguish power state from media activity.
Siemens
6ES7677-1DD50-2AA0 receives power through the controller extension bus and exposes the computer interfaces needed by external display, network and peripheral equipment.
The front-panel connectors on
6ES7677-1DD50-2AA0 keep Ethernet, DVI-I, RS232 and USB traffic on separate physical interfaces.
Media access on
6ES7677-1DD50-2AA0 is reported by the CARD LED for both CF and SD/MMC storage, while the ON LED reports module power independently.
The Siemens 6ES7677-1DD50-2AA0 S7-mEC EM PC Expansion Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

External PC Connection Paths
- Network port: One RJ45 interface carries 10/100/1000Mbit/s Ethernet traffic.
- Graphics output: DVI-I provides the connection to a local display.
- Serial path: The V.24 connector serves RS232 communication.
- USB paths: Two USB 2.0 ports connect separate high-speed peripherals.
Media Slots and CARD Indication
- CompactFlash slot: One position accepts the controller's CF medium.
- SD/MMC slot: A separate combination position accepts either supported card type.
- Access state: The CARD LED flashes while either inserted medium is being accessed.
- Presence state: The CARD LED remains lit when at least one supported medium is inserted.
Extension-Bus Supply Distribution
- Supply source: 6ES7677-1DD50-2AA0 draws operating power from the S7-mEC extension bus.
- Total allowance: The documented 14W load includes the allowance assigned to both USB ports.
- USB load: Each USB 2.0 connection is rated for the stated 500mA peripheral load.
- Power indication: The ON LED reports whether the module receives extension-bus power.
Operating State and Installation Limits
- Local indicators: ON and CARD separate module-power and storage-access conditions.
- Protection boundary: The IP20 enclosure requires protected installation inside the controller assembly.
- Operating range: Module operation is specified from 0 to 50°C.
- Storage range: Non-operating storage is specified from -40 to 70°C.
