Analog Input Modules
The analog input modules provide 16-bit measured data and 8 control/status bits
per channel.
The controller only uses the 8 control/status bits internally for
configuration/parameterization (e.g., via WAGO-I/O-
CHECK
).
Therefore, only the 16-bit measurement values for each channel are in Intel
format and are mapped by word in the input process image for the controller.
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.
Information on the structure of control and status bytes
For detailed information on the structure of a particular I/O
module’s
control/status bytes
, please refer to that module’s manual. Manuals for each
module can be found on the Internet at

15.3.3.3 3-Phase Power Measurement Module
The above Analog Input Modules have a total of 9 bytes of user data in both the
Input and Output Process Image (6 bytes of data and 3 bytes of control/status).
The following tables illustrate the Input and Output Process Image, which has a
