24 CoE: IO-Link module identification
The module identification serves to adjust the configured with the actually finished
modules
The device carries this adjustment out by verifying the vendor ID and the Device
ID The configuration data about the Vendor ID and the Device ID are in the
objects 8000
to 8070
hex
tool The IO-Link master provides the information about the connected modules in
the objects 9000
hex
A verification is only done if the sub-objects 0x80n0:04 (Device ID) and 0x80n0:05
(Vendor ID) have been configured as unequal to zero for the corresponding port
(n)
If there is no verification because no Device ID and Vendor ID were entered and
if the configured data lengths of a module are not correct, then only the amount of
data is transmitted that had been configured
Example
A real IO-Link device with 16 byte input process data is connected However, only
eight bytes were configured, so only eight bytes are transmitted
