Differences between IO-Link specifications V1.0 and V1.1
Specification
The technical definition of the IO-Link system is described in a specification of the IO-Link
consortium. The first step was the creation of specification version 1.0. The further
development and added functions of the IO-Link system led to version 1.1.
The main enhancements of version 1.1 are:
● Data backup for device replacement during operation (Backup&Restore)
● Data transmission rate 230.4 kBaud is mandatory for the IO-Link master
Combination of IO-Link devices
Note the following when combining IO-Link devices:
● Only IO-Link devices that comply with V1.0 can be operated on the IO-Link master to
V1.0.
● IO-Link devices that comply with V1.0 and V1.1 can be operated on the IO-Link master to
V1.1.
● Data backup and a data transmission rate of 230.4 kBaud of the IO-Link master after
V1.1 can only be used when these functions are also supported by the IO-Link device.
