The Siemens 6AG1155-5AA01-7AB0 Interface Module is part of the SIPLUS ET 200MP product family and is designated as IM 155-5 PN ST. It provides the communication interface required for connecting ET 200MP distributed I/O modules to a PROFINET IO network.
The module is based on the standard 6ES7155-5AA01-0AB0, but the SIPLUS version incorporates conformal coating to improve suitability for demanding environmental conditions. Its extended temperature capability makes it especially useful for industrial installations where standard automation equipment may require additional environmental protection.
Communication is provided through two RJ45 Ethernet ports and an integrated switch. The interface supports PROFINET IO, MRP, IRT, Shared Device, TCP/IP, SNMP, and LLDP functions. These capabilities allow the module to fit into a variety of modern industrial Ethernet architectures.
The 6AG1155-5AA01-7AB0 can support up to 12 I/O modules without an additional power supply, with expansion to 30 I/O modules when additional power supplies are installed. This provides flexibility when designing distributed I/O stations of different sizes.
Another important feature is its support for isochronous operation and IRT, with a shortest clock pulse of 250 μs. This makes the module suitable for applications where deterministic communication and synchronized process data are important.
For industrial automation projects, the module offers a useful combination of ET 200MP modularity, PROFINET communication, network redundancy, and SIPLUS environmental protection. It is therefore a practical choice for demanding distributed I/O applications and for replacement projects involving existing SIPLUS ET 200MP installations.

SIPLUS PROFINET distributed I/O
The Siemens 6AG1155-5AA01-7AB0 is a strong choice for ET 200MP systems that require PROFINET IO communication, modular I/O expansion, MRP networking, IRT capability, and enhanced environmental protection. Its conformal-coated SIPLUS construction makes it especially valuable for industrial installations where temperature and environmental conditions are more demanding.
Applications
Distributed ET 200MP I/O Systems
The primary role of the 6AG1155-5AA01-7AB0 is to provide the communication interface between an ET 200MP station and a PROFINET IO controller. It allows connected I/O modules to exchange process data with the higher-level automation system.
Factory Automation
The module can be installed in distributed machine-control architectures where I/O modules are positioned close to sensors, actuators, valves, drives, and other field equipment.
Industrial Process Equipment
