Digital Output Modules
The module/submodule types are listed for the digital 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 bits allocated in the respective process image for the individual submodules
(in bytes) and furnished with information (in bits).
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 digital output modules is divided into eight module types.

Digital output modules without diagnostics information in the input process image
receive the provider status (IOPS) from the IO controller and supply it with the
consumer status (IOC) of the existing output information.
