The 6ES7 155‑5AA01‑0AB0 is an interface module (head / PROFINET‑IO interface) for the ET 200MP distributed I/O system. Its module type designation is IM 155‑5 PN ST.It provides the link between a PROFINET‑network
(Ethernet) and a set of ET 200MP I/O modules (digital/analog/input/output/other), allowing distributed I/O remote from the main PLC.It includes an integrated 2‑port switch with RJ45 connectors for PROFINET network
connection.The module supports PROFINET IO‑Device functionality, i.e., acts as a remote IO station on a PROFINET network.It supplies power to the ET 200MP backplane bus: the integrated supply can
feed I/O modules; the module’s power feeding to backplane is rated at 14 W.In short: this module serves as the “gateway / brain interface” that connects a group of ET 200MP distributed I/O modules
to a PROFINET network, enabling scalable and distributed I/O systems in industrial automation — particularly useful when central PLC racks are impractical.
Frequently Asked Questions About 6ES7 155-5AA01-0AB0
|
Q: What is 6ES7 155-5AA01-0AB0 used for? A: It’s used to connect an ET 200MP modular I/O station to a PROFINET network, acting as a PROFINET‑IO Device (remote I/O station). This lets you put I/O modules remotely, distributed across a plant, while central control remains via PROFINET. Q: Can it work standalone, or needs additional modules? alone does not provide direct I/O channels. Q: What are operating environment / mechanical constraints? cabinet / indoor industrial environments, not harsh outdoor or high‑moisture |
