PRODUCT DESCRIPTION
Connect ET 200MP distributed I/O to PROFIBUS DP
Siemens 6ES7155-5BA00-0AB0 is the SIMATIC ET 200MP IM 155-5 DP ST interface module. It connects a distributed I/O station to a PROFIBUS DP master through an RS485 interface, transferring the data of compatible S7-1500 I/O modules rather than measuring field signals directly.
The integrated power supply feeds the backplane bus, supporting up to twelve I/O modules within the permitted power budget. Before commissioning, verify the station configuration, PROFIBUS address, bus connection and supply. Network communication and field wiring must match the installed hardware and applicable Siemens documentation.

ACTUAL APPLICATIONS
Distributed I/O communication in factory automation systems
These Siemens application examples illustrate possible engineering contexts, not confirmed installations of this exact article. The IM 155-5 DP ST can connect a compatible ET 200MP station only through PROFIBUS DP; it does not replace field I/O modules, PLC logic or a PROFINET interface.
-
01 · PACKAGING MACHINERY
Remote I/O communication for forming and sealing equipment
Siemens' Form, Fill and Seal application coordinates product feeders, dosing units and sealers. In a separately engineered PROFIBUS-based machine, this interface can exchange the installed ET 200MP modules' status data and output commands with the DP master; the controller retains the packaging sequence and motion functions. -
02 · MIXING AND FILLING
Distributed station communication for mixing and can filling
Siemens' color-mixing example combines recipe control, remote I/O and conveyor-fed cans. Its demonstrated network is PROFINET, not this module's network. For a separately designed PROFIBUS DP implementation, the IM 155-5 DP ST links compatible ET 200MP I/O to the DP master; it does not execute recipes or directly measure process variables. -
03 · FACTORY MATERIAL HANDLING
Station data exchange for conveyor grouping and infeed
Siemens' Intelligent Belt and Intelligent Infeed applications group arriving products and control their spacing. Where the engineered conveyor system uses PROFIBUS DP, this interface provides station-level I/O data exchange. Sensor acquisition, drive control and time-critical synchronization require their own suitable modules and validated configuration.

SIMATIC ET 200MP / PROFIBUS DP ARCHITECTURE
Integrate the ET 200MP station with its PROFIBUS master
The IM 155-5 DP ST operates as a PROFIBUS DP device with DPV1 services. It provides the communication link between an ET 200MP station and its DP master. Field sensors and actuators connect through compatible I/O modules; this interface is neither a standalone PLC nor a PROFINET IO device.
Connect the 24 V DC supply and the PROFIBUS RS485 bus according to the official terminal diagram. Select one unused station address from 1 to 125 and match it in the engineering project. A changed DIP-switch address takes effect only after the documented power-off/power-on transition.
The integrated supply provides 14 W for a single power segment with up to twelve I/O modules, subject to the station power budget. The current catalog allows 244 input bytes and 244 output bytes per station, with up to 64 bytes in each direction per module. Use the configuration supported by the actual installed versions.
Features:
- Exact article: 6ES7155-5BA00-0AB0
- PROFIBUS DP master, unique station address and compatible I/O
- Check the power budget, address space and actual module arrangement
The Siemens 6ES7155-5BA00-0AB0 interface module requires the DP master, station address, I/O configuration and power budget to be verified before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Match the complete 6ES7155-5BA00-0AB0 order number and the IM 155-5 DP ST designation. Compare the installed functional status, firmware and engineering configuration. An IM 155-5 PN model uses a different network and is not a direct PROFIBUS replacement merely because it belongs to the ET 200MP family.
Do not exchange this module while the equipment remains energized: Siemens lists no hot-swapping support. Follow the plant isolation procedure, preserve the documented station address and bus wiring, and check the U connectors and power budget. After replacement, validate data exchange and review the station and CPU diagnostic information.
The current Siemens product page lists Active Product while also announcing planned phase-out and referring to SIOS 109989704. No exact withdrawal date or drop-in successor is confirmed here. Check the current Siemens notice and the actual quoted hardware before ordering; a catalog firmware entry does not identify the version of a supplied unit.
Features:
- Match the exact PROFIBUS article and installed version
- Isolate power; verify address, wiring and U connectors
- Validate I/O data exchange and diagnostic status after replacement
The Siemens 6ES7155-5BA00-0AB0 PROFIBUS DP interface module requires replacement verification against the complete article, installed version, PROFIBUS configuration and station power budget before commissioning.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ES7155-5BA00-0AB0
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can 6ES7155-5BA00-0AB0 connect directly to a PROFINET network?
No. It is a PROFIBUS DP interface with an RS485 port, not a PROFINET IO device. The controller must provide a compatible PROFIBUS DP master connection; a PROFINET interface module is not interchangeable without reviewing the complete network and station configuration. -
How many I/O modules can the IM 155-5 DP ST supply?
Siemens specifies a maximum of twelve I/O modules and 14 W of integrated backplane infeed power. The permissible installed count depends on the modules' combined power demand; reaching twelve slots does not by itself prove that the station power budget is adequate. -
What input and output address space is available?
The current Siemens catalog specifies up to 244 input bytes and 244 output bytes per station, and up to 64 bytes in each direction per I/O module. Confirm the address requirements and supported configuration against the actual installed interface and I/O module versions. -
How do I set or change its PROFIBUS address?
Set a unique address from 1 to 125 with the front DIP switch and use the same address in the configuration software. The manual states that a changed address becomes active after power is switched off and on; perform this transition under the site's safe shutdown procedure. -
Is a PROFIBUS connector included?
Siemens' current product description includes PROFIBUS connection plug 6ES7972-0BB70-0XA0, and the manual identifies a nine-pin Sub-D connector in the manufacturer package. For the offered spare part, confirm the actual connector and accessory scope in the written quotation. -
Which engineering software can configure this module?
The current Siemens catalog lists configuration in STEP 7 TIA Portal from V13 and configuration in STEP 7 using a GSD file. Select the applicable device description and match the real module arrangement, station address and installed firmware; do not use another interface model's configuration. -
Can this interface module be replaced without switching off power?
No. Hot swapping is not supported for this article. Isolate the affected equipment according to the plant procedure before replacement, and validate the bus connection, station address, U connectors, power budget and I/O data exchange before returning the machine to service. -
What should an engineer check when the ERROR LED flashes?
Read the interface diagnostics, module status and CPU diagnostic buffer. The Siemens manual associates flashing ERROR with group or channel errors and configuration mismatches. Check for missing, faulty or unconfigured modules and power-budget faults; the LED alone does not identify a single universal cause.
