Siemens 6ES7155-6AR01-0AN0 SIMATIC ET 200SP IM 155-6 PN Basic PROFINET Interface Module

The Siemens 6ES7155-6AR01-0AN0 is a SIMATIC ET 200SP IM 155-6 PN Basic PROFINET interface module that heads a station of up to 16 ET 200SP I/O modules over two integrated RJ45 ports. It supports PROFINET IRT down to 1ms cycle time, MRP media redundancy, hot swapping, and runs on 24V DC drawing 200mA typical.

Technical Specifications

Selection Notes

The two-port integrated switch and MRP/MRPD support let this IM 155-6 PN Basic head unit sit in a ring topology for bumpless recovery from a single cable break — choose a High Feature or High Speed IM variant instead if the application needs isochronous PROFINET below the 1ms cycle time or more than the 6 local coupling channels this Basic module offers. Hot-swap support (multi-hot swap) means individual I/O modules downstream can be replaced without powering down the whole station, which matters for stations with 16 modules where a single fault shouldn't force a full station stop. PROFINET Security Class 1 with signed firmware updates is the baseline security level in the ET 200SP interface-module range — confirm the security class needed at commissioning before assuming this Basic variant meets a higher-class network security policy.

Applications

Heads a decentralized ET 200SP I/O station on a PROFINET line — machine-local or remote I/O drops in packaging, material handling, and process automation where up to 16 I/O modules and ring-redundant PROFINET are needed.
