Analog Output Modules
The analog output modules provide 16-bit output values and 8 control/status bits
per channel. DeviceNet
TM
does not use the 8 control/status bits, however, i.e., it
does not access or evaluate them.
Therefore, only the 16-bit output values for each channel are in Intel format and
are mapped by byte in the output process image for the fieldbus with the
DeviceNet
TM
fieldbus controller.
If digital output modules are in the node, the analog output data is mapped first
into the output process image, followed by the digital output data.
Each output channel occupies one instance in the “Analog Output Point Object”
(Class 0x68).

These output modules represent 2 x 2 bytes and occupy 2 instances in class
(0x68).
