Example:Processdatamapping(Configuration:UR20-4COM-IOL-16BYTE-INOUT)
The process data length of the UR20-4COM-IO-LINK module
is adjustable and can be adjusted to the respective IO-Link
device conguration. The procedure for adjusting the pro-
cess data length depends on which eldbus coupler and
which engineering tool you are using (see Chapter 6).
The rst two bytes of the input data and output data respec-
tively contain the process data of the module. This is fol-
lowed by the process data of the IO-Link device connected.
Mapping of the process data for the individual IO-Link de-
vices to the process data of the module is dened with the
„Process data length input“ and „Process data length output“
parameters of the respective IO-Link port.
You can read out the mapping of the process data
(see section 6.9).
