Overall Configuration

The maximum total length of a fieldbus node without fieldbus coupler/controller
is 780 mm including end module. The width of the end module is 12 mm. When
assembled, the I/O modules have a maximum length of 768 mm.
Examples:
• 64 I/O modules with a 12 mm width can be connected to a fieldbus
coupler/controller.
• 32 I/O modules with a 24 mm width can be connected to a fieldbus
coupler/controller.
Exception:
The number of connected I/O modules also depends on the type of fieldbus
coupler/controller is used. For example, the maximum number of stackable I/O
modules on one PROFIBUS DP/V1 fieldbus coupler/controller is 63 with no
passive I/O modules and end module.
Observe maximum total length of a fieldbus node!
The maximum total length of a fieldbus node without fieldbus coupler/controller
and without using a 750-628 I/O Module (coupler module for internal data bus
extension) may not exceed 780 mm.
Also note the limitations of individual fieldbus couplers/controllers.
Increase the total length using a coupler module for internal data bus
extension!
You can increase the total length of a fieldbus node by using a 750-628 I/O
Module (coupler module for internal data bus extension). For such a
configuration, attach a 750-627 I/O Module (end module for internal data bus
extension) after the last I/O module of a module assembly. Use an RJ-45 patch
cable to connect the I/O module to the coupler module for internal data bus
extension of another module block.
This allows you to segment a fieldbus node into a maximum of 11 blocks with
maximum of 10 I/O modules for internal data bus extension.
The maximum cable length between two blocks is five meters.
More information is available in the manuals for the 750-627 and 750-628 I/O
Modules.
