2.6.1 Installation Position

Along with horizontal and vertical installation, all other installation positions
are allowed.
Attention
In the case of vertical assembly, an end stop has to be mounted as an
additional safeguard against slipping.

2.6.2 Total Expansion

The length of the module assembly (including one end module of 12mm
width) that can be connected to the coupler/controller is 780mm. When
assembled, the I/O modules have a maximum length of 768mm.
Examples:
• 64 I/O modules of 12mm width can be connected to one coupler/controller.
• 32 I/O modules of 24mm width can be connected to one coupler/controller.
Exception:
The number of connected I/O modules also depends on which type of
coupler/controller is used. For example, the maximum number of I/O modules
that can be connected to a Profibus coupler/controller is 63 without end
module.The maximum total expansion of a node is calculated as follows:
Warning
The maximum total length of a node without coupler/controller must not
exceed 780mm. Furthermore, restrictions made on certain types of
couplers/controllers must be observed (e.g. for Profibus).
