Analog Output Modules

The module/submodule types are listed for the analog output 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 output modules is divided into two module types.

Analog output modules receive the provider status (IOPS) from the I/O controller
and supply it with the consumer status (IOCS) of the existing output information
if only the actual user data is replaced. If all existing information is available in
the process image of the inputs and outputs, the process data qualifiers are also
transmitted in the opposite direction.
The group of analog output modules is divided into the following submodule
types.
