Analog Input Modules
The module/submodule types are listed for the analog input modules and the
substitute I/O modules assigned in the tables below.
The subsequent tables for the submodule types and data lengths list the number of
data bytes provided in the respective process image for the individual submodules.
The respective number of bytes of the telegrams in the send and receive direction
is also specified as input IOD
IOC (provider) and output IOC
IOD
(consumer).
The group of analog input modules is divided into three module types, which are
divided into five submodule types.
