f) Assigning mapping I/O assemblies to available I/O connections
The PSE2xxDN allows the user to change how mapping I/O assemblies are assigned
to available I/O connections. The current settings for each type of I/O connection are
recorded in the connection object (class ID 5), instance 0, attr. 100-104. The following
provides possible settings and default values:
Name
Attr.
No.
