Serial Interfaces and Gateways

The group of serial interfaces and their gateways is divided into
5 types of modules:
Type of module
The provider and consumer status (IOPS) of the input or output information
are exchanged between the I/O controller and I/O device in both directions
with serial interfaces and their gateways.
The following table shows a list of the number of bytes for the individual
modules that are allocated in the respective process image (PA) and the
telegrams (TLG) in the direction of transmission and reception (Tx, Rx).
