Features:
- Connects an ET 200SP station containing up to 30 I/O modules to a PROFINET controller.
- Coordinates isochronous updates at a 0.125 ms shortest clock and supports multi-hot-swap.
- Uses a selectable BusAdapter for the physical PROFINET ports and a server module to terminate the station.
The interface module converts controller telegrams into the input and output address areas assigned to the station modules.
PROFINET timing, device naming and module order must agree with the engineering project before cyclic exchange starts.
The two-port network path, station backplane and 24 V supply remain separate connection domains with different responsibilities.
The Siemens 6ES7155-6AU00-0DN0 ET 200SP IM 155-6 PN High Speed Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Moving controller data through the ET 200SP backplane
- Controller side: The PROFINET IO controller sends output data and receives input data through the interface module.
- Station image: The interface module combines module address areas into the complete station input and output images.
- Module boundary: Each installed I/O module contributes no more than its configured 32-byte input and output allocation.
Coordinating real-time communication
- Isochronous clock: A shortest 0.125 ms cycle aligns distributed I/O updates with controller execution.
- IRT: Isochronous real-time communication carries scheduled traffic through the PROFINET path.
- MRP and MRPD: Media redundancy functions define how the station remains reachable in an engineered ring.
Keeping station structure under control
- Multi-hot-swap: Configured module groups can be changed while unaffected sections continue operation.
- Sequence check: The physical row must match the configured module sequence and slot addresses.
- Server module: The server module closes the internal bus after the last installed I/O module.
Matching software to the interface firmware
- TIA Portal: The documented configuration starts with TIA Portal V14 for the listed firmware level.
- STEP 7: Classic engineering is documented from STEP 7 V5.5 SP4.
- GSDML: A V2.32 device file maps the module when engineering uses the PROFINET description route.
