12.2.4 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 coupler/controller with MODBUS/TCP does not have access to the
8 control/status bits.
Therefore, the coupler/controller with MODBUS/TCP can only access the 16 bits
of analog data per channel, which are grouped as words and 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.

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
