Product Overview

6ES7155-6AU00-0DN0 is the IM 155-6 PN HS high-speed PROFINET interface module for SIMATIC ET 200SP distributed I/O. The order item includes a server module and connects the station to a PROFINET IO controller.

The module supports up to 30 modules per rack, high-speed isochronous operation, shared-device configurations, and network diagnostics.

Ordering focus: Select the BusAdapter for the project cabling and retain the supplied server module at the end of the ET 200SP station.

Key Functions

High-speed I/O update

Isochronous operation supports a minimum 125 µs bus cycle and IRT cycle choices from 125 µs to 4 ms.

Flexible network topology

The integrated two-port switch works with selectable copper or fiber BusAdapters and can act as an MRP or MRPD client.

Station diagnostics

RUN, ERROR, MAINT and power LEDs, together with channel diagnostics, help identify operating and fault states.
