Cfg name
FastDeviceStartup
Description
The parameter Fast Device Startup specifies if the I/O device should use a faster
connection attempt algorithm or not.
Usage
The parameter Fast Device Startup is used mainly to speed up tool change
applications. The usual PROFINET connection attempt takes a few seconds to
complete, but with Fast Device Startup enabled devices, this time is shortened to
less than a second. For more information, see
Using Fast Device Startup on
page 44 .
Prerequisites
The option PROFINET Controller/Device must be installed.
Limitations
The Ethernet switches between the IRC5 controller and the I/O device that uses
the
Fast Device Startup functionality. It must be configured to disable the auto
crossover and automatic speed detection functions on used connectors. The speed
rate is set to 100Mbps (full duplex).
Default value
The default value is Deactivated .
Allowed values
• Deactivated
• Activated
• Support
Note
Select Support to set the desired port speed. For port speed, select 100 Mbps
and the port speed is adjusted to 100Mbps, and auto negotiation is turned off
for the port.
Hence, it is possible to change the settings on a built-in switch for a PROFINET
I/O device.
