SIPROTEC 4, Communication Module PROFINET IO, Communication Profile
C53000-L1840-C360-1, Edition 08.2012
PROFINET IO Bus Interface DAP (Device Access Point)
The DAP module is always plugged in at slot 0 of the IO device and cannot be removed. The module describes
the physical device data such as interface and port. In addition, it is possible to read or write device-related
diagnoses and acyclic telegrams.
*) I&M data = data for device identification and maintenance

None
Parameters
Each single-point indication can be assigned to the process alarm
(see Chapter 2.7).
Default setting: all not assigned
NOTE

(see Figure 2-14) is not identical with the PROFINET IO mapping data-
object number. It refers to the indication in this IO module. The indication number in each IO module starts with
number 1.
