Features:
- The 6-inch OP 177B DP uses a blue-mode STN display with touch screen and membrane-key input.
- MPI and PROFIBUS DP provide the documented automation communication paths.
- The listed RS485/RS422, USB, printer, and MMC connections cover local interfaces and project media.
The front layout makes the screen and membrane keys available as separate operator controls. Function keys can be assigned in the HMI project for global, local, or system actions.
On the DP version, MPI or PROFIBUS DP carries automation traffic; local serial and USB connections remain separate.
The card slot accepts the product's MMC project medium, while the separate printer interface gives the panel a documented output connection.
The Siemens 6AV6642-0DC01-1AX1 SIMATIC OP 177B 6-inch DP Operator Panel 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.
Control methods
- Touch screen: The display uses a resistive analog touch screen for screen-based input.
- Membrane keyboard: The OP 177B includes a membrane keyboard alongside touch operation.
- Function keys: Project configuration can assign OP 177B function keys as global, local, or system keys.
- Operator actions: Touch and key inputs remain available as separate controls on the panel front.
Fieldbus path
- MPI: The OP 177B DP supports MPI for the documented SIMATIC controller connections.
- PROFIBUS DP: The DP panel supports PROFIBUS DP communication at up to 12 Mbps.
- Bus connections: Up to four connections can use the same bus.
- DP identity: The current order number identifies the DP form rather than the OP 177B PN/DP form.
Peripheral connections
- Serial port: RS485/RS422 is the panel's IF 1B interface.
- USB port: The panel includes a USB interface for local connection tasks.
- Printer port: A separate printer interface is included in the configuration.
- Interface roles: These local connections remain separate from the MPI/PROFIBUS DP communication path.
Engineering context
- Configuration tool: 6AV6642-0DC01-1AX1 is configurable with WinCC flexible 2005.
- MMC slot: The panel provides a slot for the listed MMC project medium.
- Program memory: OP 177B specifications identify 2 MB of program memory.
- Project record: The installed DP path and the WinCC flexible project version need to remain associated with the panel record.
