It comes with a 2-year warranty and has a rated current consumption of 450 mA, while its maximum current consumption is 550 mA. The interface module also has a maximum inrush current of 3.7 A and a power loss of 1.9 W. It operates with a rated supply voltage of 24 V and supports up to 256 submodules per station. The interface types supported by this module are Profinet and RJ45, and it has two interface ports with a switch. The module comes with a BusAdapter of BA 2x RJ45, BA 2x FC and supports protocols such as Profinet I/O, Open IE Communication, and Media redundancy. The Open IE communication protocols supported by the module include TCP/IP, SNMP, and LLDP.

The product type of this device is called IM 155-6 PN ST, and it is currently in the functional status of FS03.

This product supports I&M data from I&M0 to I&M3, and it allows for module swapping during operation, also known as hot swapping, in a single hot swapping configuration. However, it does not support isochronous mode.

This device can be engineered using the STEP 7 TIA Portal from version V14 and with STEP 7 from version V5.5 SP4 and above. It also supports PROFINET with GSD version/GSD revision V2.3 / - for configuration and integration.

The Siemens 6ES7155-6AU01-0BN0 has a configuration control via dataset and operates with a rated supply voltage of 24V DC. Its permissible range for the supply voltage is between 19.2V DC and 28.8V DC. The device features reverse polarity protection and short-circuits protection. Additionally, it has mains buffering capabilities with a stored energy time of 10 ms in the event of a mains/voltage failure. The device has a rated current consumption of 450mA, with a maximum current consumption of 550mA and a maximum inrush current of 3.7A. The I²t value for the device is 0.09 A²·s. It has an infeed power to the backplane bus of 4.5W and a typical power loss of 1.9W.

The device supports RJ45 (Ethernet) interface types for communication. It allows for PROFINET transmission with a speed of 100 Mbit/s full duplex (100BASE-TX) and also supports 10 Mbps for Ethernet services and 100 Mbps for PROFINET communication.

The device supports several protocols including PROFINET IO Device and Open IE communication. It also supports media redundancy with PROFINET MRP.

Open IE communication protocol is supported by the device, with compatibility for TCP/IP, SNMP, and LLDP.

The device has several LED indicators for diagnostics, including a green RUN LED, a red ERROR LED, and a yellow MAINT LED. Additionally, there is a green PWR LED for monitoring the supply voltage. The device also features a connection display with 2x green link LEDs on the BusAdapter for LINK TX/RX.

The Siemens 6ES7155-6AU01-0BN0 device can be connected via ET-Connection using BU/BA Send with up to 16 ET 200AL modules. The device has a width of 50mm, a height of 117mm, and a depth of 74mm. Its approximate weight is 147g, excluding the BusAdapter.
