Industrial 6ES7155-6AR00-0AN0 ET 200SP Module

SIMATIC ET 200SP PROFINET interface module IM 155-6PN BA Basic, 6ES7155-6AR00-0AN0, provides the PROFINET interface for the ET 200SP distributed I/O system. The unit combines an IM 155-6 PN BA interface module with a server module and two integrated RJ45 sockets, delivering a built‑in switch function and a direct path to the PLC for IO data. It supports up to 12 peripheral I/O modules per ET 200SP station and exposes a single PROFINET interface for IO data exchange. The address space per station for IO data is 32 bytes for inputs and 32 bytes for outputs. Firmware updates are supported, and Siemens lists a successor model 6ES7155-6AR01-0AN0. This module belongs to the IM 155-6 PN BA family and is used to connect ET 200SP IO in PROFINET networks.
