Characteristics of an I-device
An I-device is included in an IO system like a standard IO device.
I-device without lower-level PROFINET IO system
The I-device does not have its own distributed I/O. The configuration and parameter
assignment of the I-devices in the role of an IO device is the same as for a distributed I/O
system (for example, ET 200).
