Table 3-4 Interface module (module for PROFINET IO)
Function Figure
The interface module:
● Connects the IO device to the IO controller
● Exchanges data with I/O modules via the backplane bus.
Table 3-5 BusAdapter
Function Figure
The BusAdapters for PROFINET IO allow you to freely choose the
connection system for the IO device. Several versions of the BusA‐
dapter are available for the interface modules (see documentation
SIMATIC Distributed I/O; BusAdapter for distributed I/O (https://
support.industry.siemens.com/cs/ww/en/view/109747250)):
Examples:
● BusAdapter with standard RJ45-connector
(BusAdapter 2×RJ45) ①
● BusAdapter with FastConnect connector for direct connection of
the bus cable (BA 2×FC) ②
● BusAdapter with connector for fiber-optic cable (BA 2xLC) ③
Table 3-6 Carrier module
Function Figure
The carrier module routes the backplane bus to all I/O modules. The
power bus is extended depending on each placed terminal block.
Carrier modules for I/O modules are available in the following ver‐
sions:
● Carrier module 2x
● Carrier module 8x
Note:
The fixing screws are secured for transport in the factory state.
Remove these transport locks before tightening the fixing screws.
