Planning

This section provides helpful information for planing the use of the I/O system.

5.1 Node Structure

Note that product-specific configuration or test steps may be necessary. For example be-
fore:
• Commissioning
• Recommissioning
• Exchange and replacement of I/O modules
These configuration or test steps are described in the respective
Types of Components
Several different types of components are used in the I/O system:
• Head Stations:
– PFC
– Controller
– Fieldbus couplers
• I/O Modules:
– Analog input and output modules
– Digital input and output modules
– Function and technology modules
– Communication modules
– Supply and segment modules
Node Configuration
A node configuration consists of at least the following:
• A head station
• A power supply
• An I/O module
• An end module
Structuring a Node
When planning a node, please take the following into account:
• Grouping by potential group
• Optical delimitation of the potential groups
For fast, effortless planning, use the WAGO Configurator Smart Designer.
Number of I/O Modules
The maximum number of I/O modules that can be operated in one node depends on sev-
eral factors:
• Mechanical Expansion:
The distance between a head station and an end module must not exceed 768 mm, in-
cluding the end module. If your node is wider, it must be divided into several sections
with an additional fieldbus coupler, controller or internal data bus extension.
