2.4 IO Modules
30 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
IO Module Single-Point Indications 16
Figure 2-14 Single-Point Indication 16
Cyclic data exchange None

(standard PROFINET IO services)
• Reading of diagnostics data and I&M data 0, 1, 2, 3, 4
*)
• Writing of I&M data 1, 2, 3, 4
Acyclic reading/writing of data
(SIPROTEC-specific)
None
Parameters None
Single-point indications 16
Category in the hardware catalog Input data
Data type 16 single-point indications; see Chapter 2.3.1
Data size 2 bytes
Acyclic reading/writing of data None
Parameters Each single-point indication can be assigned to the process alarm
(see Chapter 2.7).
Default setting: all not assigned
NOTE
The indication number indication x (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.
