15.1.5.18 KNX/EIB/TP1 Module
753-646
The KNX/TP1 module appears in router and device mode with a total of 24-byte
user data within the input and output area of the process image, 20 data bytes
and 2 control/status bytes. Even though the additional bytes S1 or C1 are
transferred as data bytes, they are used as extended status and control bytes.
The opcode is used for the read/write command of data and the triggering of
specific functions of the KNX/EIB/TP1 module. Word-alignment is used to assign
12 words in the process image. Access to the process image is not possible in
router mode. Telegrams can only be tunneled.
In device mode, access to the KNX data can only be performed via special
function blocks of the IEC application. Configuration using the ETS engineering
tool software is required for KNX.

15.1.5.19 AS-interface Master Module
750-655,
753-655
The length of the process image of the AS-interface master module can be set to
fixed sizes of 12, 20, 24, 32, 40 or 48 bytes.
It consists of a control or status byte, a mailbox with a size of 0, 6, 10, 12 or 18
bytes and the AS-interface process data, which can range from 0 to 46 bytes.
The AS-interface master module has a total of 6 to maximally 24 words data in
both the Input and Output Process Image. Word alignment is applied.
The first Input and output word, which is assigned to an AS-interface master
module, contains the status / control byte and one empty byte.
