4 Control
4.1 I/O Assembly Instances
I/O assembly instances are some dened process control objects with dened content comprising control and status
information.
Unlike DeviceNet, it is possible to run with asymmetrical instances. For example, 101/153 = 8 bytes/20 bytes.
It is not possible to mix instances across proles, for example 20/100. Assembly instances must be consistent to the ODVA
or frequency converter prole.
Read the controlling instance in chapter 5.2.3 12-2* Process Data.
