5.4 Configuration of the LioN-P
EtherNet/IP modules
5 Configuration and startup
5.4.2.6 IO mapping configuration (for 16DIO modules only)
Configuration of the IO mapping makes it possible to change the data
structure of the E/A data. By default each E/A channel is mapped in sequence
in the process data. Existing PLC programs however, may under certain
circumstances, use another channel assignment.
These parameters enable all E/A channels to be freely assigned a bit
in the E/A data. It should be noted that duplicate assignments are
not possible here. If faulty parameterization of the IO mapping when
transferring the configuration is detected,the LioN-P module registers a fault.
A misconfiguration can be viewed with the status page of the web interface.
The permitted value range and the default value of the parameters depend on
the selected profile. A channel can also be set to inactive with the value 255.
For example, if a channel has been configured with the value 3, its status
value will be transferred to the third bit of the process data. This applies to both
data directions if this has been configured through the process data direction
of the channel. For more information on the process data, see
on page 61.
