14.1.3 Digital Input/Output Modules
The module/submodule types are listed for the digital input/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).
There is one module type for the digital input/output modules.

8-Channel Digital Input/Output Modules 750-1502, 750-1506
Digital input/output modules receive the provider status (IOPS) of the available
output information as well as the consumer status (IOCS) of the received input
information from the IO controller. They provide the IO controller with the
consumer status (IOCS) of the received output information as well as the provider
status (IOPS) of the available input information.
There are the following submodule types for the digital input/output modules.
