5.1 How to Control

5.1.1 I/O Assembly Instances

I/O Assembly Instances are a number of defined process control objects with defined content comprising control and status information.

Unlike DeviceNet it is possible to run with asymmetrical instances. E.g. 101/153 = 8 bytes/20 bytes.

It is not possible to mix instances across profiles, e.g. 20/100. Assembly instances must be consistent to the: ODVA or Drive profile.

The controlling instance can be read in par. EN-20, Control Instance.

The figure below shows the I/O Assembly Instance options for controlling and monitoring the AF-650 GP/AF-600 FP drive.
