Firm and hardware version
The documentation refers to the firm and hardware status that was valid at the time it was prepared.
The properties of the modules are subject to continuous development and improvement. Modules having
earlier production statuses cannot have the same properties as modules with the latest status. Existing
properties, however, are always retained and are not changed, so that these modules can always be
replaced by new ones.
The firmware and hardware version (delivery state) can be found in the batch number (D number) printed at
the side of the IO-Link box module.
Syntax of the batch number (D-number)
D: WW YY FF HH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version
Example with D no. 29 10 02 01:
29 - week of production 29
10 - year of production 2010
02 - firmware version 02
01 - hardware version 01
