Function

The bus node as a device in a PROFINET IO network establishes the connection to the higher-order
controller. The PROFINET communicates in real-time with the Real-Time Protocol (RT) or the Isochro-
nous Real-Time Protocol (IRT). The switch integrated in the bus node enables division of the network
into several segments. The number of segments in the network can be increased with the use of
additional switches and routers.
The bus node can be used in two different operating modes:
– Remote I/O
– Remote controller
Particular functions are only available from a specific revisionè 4.2.2 Product variants.
Priority start-up (Fast Start-up)
The Prioritised Start-up function is also referred to as "fast start-up" or "fast restart" and ensures a
fast start-up of the CPX terminal.
Requirements for using the function Fast Start-up:
– Intermediate switches and routers must must also support the Fast Start-up function.
Fast Start-up can be combined with the Remote I/O operating mode.
Deactivation of the crossover function speeds up the Fast Start-up function.
The Fast Start-up function is switched over in the control software at two configuration levels:
– Basic hardware configuration in the properties for the CPX terminal
– CPX terminal configuration with allocation of the configuration table
