PRODUCT DESCRIPTION
Connect a supported SMART CPU as a PROFIBUS or MPI slave
Siemens 6ES7288-7DP01-0AA0 is the EM DP01 communications expansion module for supported S7-200 SMART CPUs. Its single RS485 port provides PROFIBUS DP slave and MPI slave functions, using automatic baud-rate detection and a station address selected by rotary switches.
The DP master defines the process-data configuration, while the SMART program handles the associated V-memory buffers. Diagnostic indicators show power, configuration and data-exchange states. Module logic power and the external supply for the communications port are separate resources in the manufacturer specification.

PROFIBUS AND MPI COMMUNICATION
Coordinate the slave configuration, buffers and separate port supply
The DP01 adds a single RS485 communications interface to a documented compatible SMART CPU. Its role is a PROFIBUS DP or MPI slave, not a network master. Rotary address selection, supported automatic baud rates and the master configuration together define how the station participates in communication.
The DP master establishes the I/O configuration and V-memory buffer location, while the SMART program moves the exchanged data to and from its working areas. Siemens distinguishes configuration/status entries from actual data-exchange state, so a connected cable or populated memory field alone does not confirm valid exchange.
Module logic draws power from the 5 V SM bus, while the communications port requires 20.4 to 28.8 V DC from a Class 2, Limited Power or PLC sensor supply. POWER confirms user-supply presence; DX MODE, DIAG and DP ERROR distinguish communication and module states.
Features:
- Explicit slave communication roles
- Master-defined V-memory exchange
- Distinct logic and port power
The Siemens 6ES7288-7DP01-0AA0 requires the documented hardware configuration, installation conditions and interface arrangement to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Match the full DP01 order number and verify the actual SMART CPU against the manufacturer compatibility list, including firmware. Do not treat a generic RS485 connector or a different PROFIBUS module as proof of equivalence. The replacement must retain the documented slave role within the existing network.
Keep the GSD selection, rotary station address, master-side I/O layout and SMART V-memory mapping from the established project. After an address change, Siemens requires a CPU power cycle before it becomes effective. Review data consistency and program transfers together; special-memory writes cannot replace the DP master configuration.
Check the communications-port supply separately from SM-bus logic power, then compare the exact D-sub and X80 assignments with the drawings. Use the diagnostic indicators to distinguish supply presence from active data exchange. Qualified personnel must follow the original isolation and installation procedures when replacing the module.
Features:
- Host CPU and firmware eligibility
- GSD and buffer mapping retained
- Power and exchange-state verification
The Siemens 6ES7288-7DP01-0AA0 requires replacement verification based on its complete order number, installed hardware, signal configuration and project documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7288-7DP01-0AA0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Does DP01 turn the SMART CPU into a PROFIBUS master?
No. The documented protocols are PROFIBUS DP slave and MPI slave. A separate DP master configures the process-data exchange; this module is not described as the DP master. -
Which host CPUs are named in the compatibility table?
Siemens lists ST20, SR20, ST30, SR30, ST40, SR40, ST60 and SR60 with firmware 2.1 or later. Check the actual CPU and firmware; membership of the broader SMART family alone is not sufficient. -
How are the station address and baud rate established?
Set the station address with the rotary switches in the documented 0-99 range. Siemens requires a CPU power cycle after an address change before the new address takes effect. The module automatically detects the supported network baud rate. -
Can buffer sizes be set by writing the SMART special-memory area?
No. Siemens states that only the DP master configures the DP01 buffer sizes and location for DP operation. Special-memory entries report configuration and status; they are not a substitute for master configuration. -
What must the SMART program do with the exchanged data?
The program moves received data from the output buffer into the areas where it is used, and prepares data in the input buffer for transfer to the DP master. Preserve the agreed V-memory mapping and data consistency. -
Does 24 V DC power the module logic as well as the port?
No. The external 20.4 to 28.8 V DC supply powers the communications port, not module logic. Siemens specifies Class 2, Limited Power, or PLC sensor power. Module logic uses the 5 V SM bus; check both resources separately. -
Does an illuminated POWER indicator prove DP data exchange is active?
No. POWER indicates the presence of user 24 V DC. DX MODE identifies successful data-exchange operation, while DIAG and DP ERROR provide different configuration and fault information. -
Can S7-1200 GET/PUT access be assumed from the PROFIBUS connection?
No. The manual states that an S7-1200 DP master cannot access the SMART CPU using GET/PUT through this arrangement, although PROFIBUS Data Exchange Mode remains supported. Do not confuse DP exchange with a separate access method.
