Siemens 6ES7155-6AR00-0AN0 PROFINET Interface Module
An IM 155-6 PN Basic interface module with integrated Ethernet ports for compact ET 200SP stations.
Key Information
6ES7155-6AR00-0AN0 connects a compact SIMATIC ET 200SP station to PROFINET IO. The interface module combines network access, station control and diagnostics in the head module of the distributed-I/O assembly.
The supplied server module completes the station mechanically; the configured I/O sequence and network identity must be retained during replacement.
Functions
- Operates as a PROFINET IO device with integrated switching between the two network connections.
- Supports media-redundancy client operation for suitable ring topologies.
- Provides maintenance, error and link-status diagnostics through front LEDs and controller messages.
- Allows single-module hot swapping within the documented ET 200SP operating rules.
- Stores identification and maintenance data for station servicing.

Installation
- Mount the interface at the head of the ET 200SP station and connect the approved server module at the station end.
- Restore the PROFINET device name, IP configuration and controller assignment before returning the station to automatic operation.
- Check RJ45 shield bonding, line topology and supply polarity before energizing.
- Use the existing hardware configuration to verify every BaseUnit and electronics module position.
Lifecycle
- Product phase-out began in March 2025.
- The named successor is 6ES7155-6AR01-0AN0, which introduces a different station capacity and PROFINET security classification.
- Treat conversion to the successor as a controlled hardware-configuration change rather than an unreviewed swap.
FAQ
Can 6ES7155-6AR01-0AN0 replace 6ES7155-6AR00-0AN0 without project changes?
Not automatically. Compare station size, firmware support, security behavior and the controller hardware catalog before conversion.
What project data should be saved before replacing 6ES7155-6AR00-0AN0?
Retain the device name, IP settings, module sequence, parameter assignments and network topology.
Does 6ES7155-6AR00-0AN0 require a separate PROFINET BusAdapter?
No BusAdapter is selected for its integrated RJ45 network connection; verify that the installed cabling matches that construction.
How should an ET 200SP station using 6ES7155-6AR00-0AN0 be expanded?
Check the station’s permitted module count and power-segment design before adding hardware.
What should be tested after exchanging 6ES7155-6AR00-0AN0?
Verify controller connection, every module’s diagnostics, process-data mapping and any ring-redundancy behavior.
Which records help prevent a mismatched 6ES7155-6AR00-0AN0 spare?
Provide the full nameplate, firmware status, project version and a photograph of the station assembly.
