Siemens 6ES7155-6AR00-0AN0 Profinet Interface Module

Siemens 6ES7155-6AR00-0AN0 is the IM 155-6PN BA PROFINET interface module for the SIMATIC ET 200SP distributed I/O system, providing a dedicated PROFINET IO interface that links ET 200SP I/O modules to a PROFINET network and serves as the gateway between the controller and field devices in industrial automation installations. As the Basic BA variant, it includes a server module and features two integrated RJ45 sockets for PROFINET connectivity, enabling compact topologies and supporting configurations with up to 12 I/O modules in the ET 200SP setup. Siemens documentation describes the IM 155-6 PN BA interface module as the device that connects the ET 200SP distributed I/O system with PROFINET IO and handles the protocol communication between the PROFINET controller and the I/O modules. Typical applications include machine control and factory automation tasks where robust PROFINET IO connectivity is required across dispersed I/O points within the ET 200SP ecosystem.
