And the output modules seize 8 Instances in Class (0x66).
5.2.3 Analog Input Modules
The hardware of an analog input module has 16 bits of measured analog data
per channel and 8 bits of control/status. However, the DeviceNet cou-
pler/controller does not have access to the 8 control/status bits. Therefore, the
DeviceNet coupler/controller can only access the 16 bits of analog input data
per channel mapped in Intel format in the Input Process Image.
When digital input modules are also present in the node, the analog input data
is always mapped into the Input Process Image in front of the digital data.
Each input channel seizes one Instance in the Analog Input Point Object
(Class 0x67).
