The Siemens SIMATIC ET 200SP IM 155-6PN Basic (6ES7155-6AR00-0AN0) is a compact PROFINET interface module designed to connect up to 12 I/O peripheral modules to a PROFINET controller. It features two integrated RJ45 sockets with an embedded 2-port switch for easy line-topology network wiring. Manufactured in Germany, this module ensures reliable real-time communication for distributed I/O systems in industrial environments.
The Siemens 6ES7155-6AR00-0AN0 IM 155-6PN Basic interface module connects SIMATIC ET 200SP distributed I/O systems to PROFINET network controllers. It functions as a communication gateway, collecting field signals from peripheral I/O modules and transmitting them efficiently to a central PLC or control system.
Main Features
The IM 155-6PN Basic module handles up to 12 I/O modules along with a required server module (6ES7193-6PA00-0AA0) to complete the internal backplane bus. It includes an integrated 2-port switch with dual RJ45 ports, supporting 100 Mbps full-duplex communication and PROFINET real-time (RT) data exchange.
Benefits
Its compact footprint saves panel space while supporting flexible decentralized control layouts. Dual RJ45 connections eliminate the need for external network switches when daisy-chaining field devices. The push-in terminal system and modular backplane architecture simplify installation, maintenance, and system expansion.
Applications
This interface module is used across modern manufacturing and processing plants to connect remote sensors, actuators, and I/O modules to central PLCs (such as S7-1200, S7-1500, or S7-300). It is suited for factory automation, packaging machinery, conveyor systems, and water treatment operations.
