12.3.4 Analog Output Modules
The analog output modules provide 16-bit output values and 8 control/status bits
per channel. EtherNet/IP does not use the 8 control/status bits, 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 word in the output process image for the fieldbus
coupler/controller with EtherNet/IP.
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).
Information for the control/status byte development
Please refer to the corresponding description of the I/O modules for the structure
of the control/status bytes. You can find a manual with the relevant I/O module
