Analog Input Modules

The hardware of an analog input module has 16 bits of measured analog data
per channel. The 16 bits of analog data per channel are grouped as words and
mapped in Intel format in the Input Process Image of the EtherCAT
coupler.
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 www.wago.com.
