Analog Output Modules

The hardware of an analog output module has 16 bits of measured analog data
per channel and 8 bits of control/status. However, the coupler/controller with
EtherNet/IP does not have access to the 8 control/status bits. Therefore, the
coupler/controller with EtherNet/IP can only access the 16 bits of analog data per
channel, which are grouped as words and mapped in Intel format in the Output
Process Image.
When digital output modules are also present in the node, the analog output data
is always mapped into the Output Process Image in front of the digital data.
Each output channel seizes one Instance in the Analog Output Point Object
(Class 0x68).
Information to the structure of the Control/Status byte
For detailed information about the structure of a particular module's control/status
byte, please refer to that module's manual. Manuals for each module can be
found on the Internet under: http://www.wago.com.
