About Fast Device Startup
The Fast Device Startup functionality is used in tool changing applications to
shorten the connection time between the PROFINET controller and an I/O device.
To be able to use this functionality, the I/O device needs to support this functionality.
All devices must support fast startup in the communication chain. Devices such
as switches or other intermediate hardware that could affect the PROFINET
communication. For more information, see
on page
Some manufacturers also call this functionality Fast Start Up (FSU) or Prioritized
Startup.
To activate Fast Device Startup against an I/O device, activate the system parameter
Fast Device Startup and select the corresponding port(s) to be configured. See

In this alternative the PROFINET controller connects to the I/O device via a switch.
Enable fast device startup and select 100 MBit (full duplex) on port 1. The port
number is usually displayed upon the I/O device itself.

Note
The I/O device with FSU functionality is connected with the IRC5 controller. When
the power of the I/O device is switched off and switched on again, the IRC5
controller establishes contact with the I/O device using the fast startup sequence.
