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

SIMATIC ET 200SP PROFINET interface module IM 155-6 PN BA (6ES7155-6AR00-0AN0) provides PROFINET connectivity for the ET 200SP distributed I/O system, and arrives with a server module to support centralized I/O management within the rack. It supports up to 12 peripheral modules and includes two integrated RJ45 connectors for the PROFINET network and server communications, enabling compact cabling in space-constrained installations. As a BA (Basic) variant in the IM 155-6 PN family, this module is designed for streamlined deployments within ET 200SP racks, with Siemens noting a successor model 6ES7155-6AR01-0AN0 for future compatibility. In practical automation applications, the IM 155-6 PN BA interface module serves as the gateway between field devices and the PROFINET network, coordinating data exchange and enabling scalable expansion of remote I/O through the ET 200SP architecture.
