Product overview
MPI/DP Programming Adapter for Siemens SIMATIC S7-300 / S7-400 PLC
The MPI/DP Programming Adapter is designed to connect a computer or programming device to compatible Siemens SIMATIC S7-300 and S7-400 PLC systems through an MPI or PROFIBUS DP interface.
It provides a convenient communication bridge between the computer's USB interface and the PLC's MPI/DP RS-485 interface, making it suitable for PLC programming, commissioning, diagnostics, maintenance, program upload/download and online monitoring.
Designed for S7-300 & S7-400
MPI and PROFIBUS DP interfaces are commonly found on Siemens SIMATIC S7-300 and S7-400 automation systems. This type of programming adapter is especially useful when working with legacy PLC installations that do not provide a convenient Ethernet programming interface.

Programming & Diagnostic Use
When used with compatible Siemens programming software and drivers, the adapter allows a technician to establish an online connection with supported PLC hardware for programming and diagnostic operations.
The appropriate PG/PC interface must be selected according to whether the PLC connection is operating as MPI or PROFIBUS. Communication parameters such as network address and transmission rate must also match the existing PLC/network configuration.
Important Compatibility Information
This is a general MPI/DP programming adapter listing. Unless the adapter is specifically identified by a Siemens order number and verified as genuine Siemens hardware, it should not be represented as an original Siemens PC Adapter.
Driver support, supported Windows versions, STEP 7/TIA Portal compatibility and maximum communication speed can differ between original Siemens adapters and third-party compatible adapters. Always verify the exact adapter model before purchase.
