Basic components of the IO device
Basic components for configuration of IO devices
The following tables show the components for configuring IO devices based on the ET 200SP
HA distributed I/O.
Table 3-2
Rail
Function
Figure
The rail is the component on which the modules of the IO device are
attached.
The upper part corresponds to a standard rail (width 35 mm).
Table 3-3
Carrier module for interface module
Function
Figure
Carrier modules for interface modules are available in the following
versions:
● Carrier module for 1 interface module
(required for singular connection of the IO device to PROFINET
IO)
● Carrier module for 2 interface modules
(required for redundant connection of the IO device to
PROFINET IO)
The carrier modules connect the interface module to the backplane
bus.
They enable data exchange with the I/O modules.
Note:
Interface modules cannot be plugged in if the corresponding con‐
nector for the supply voltage is plugged in beforehand.
