AKD PROFINET | 4 Installation and Setup
4.6 Parameter Configuration with PROFIdrive over PROFINET IO
The AKD is defined as an I/O Device in PROFINET IO. A PLC or other IO-Controller estab-
lishes a connection via a so called application relations (AR). Within this AR, different pro-
files like PROFIdrive, PROFIsafe etc. can be used for the communication. The PROFIdrive
profile, which AKD supports, is defined as Application Process Identifier (API) 0x3A00.
Within the AR, further addressing needs to done. PROFINET IO divides each device in so
called slots and subslots. Sub 0 refers to the device itself and returns all generic data like
vendor name, software and hardware version. The subslots within the device can be used
with different real and virtual modules. Each module a functional component, which for
example can be a digital I/O or Telegram with Position values.
AKD provides several virtual modules, which can be used in Slot 1 and are used for the real
time data exchange.
For read or write parameters to or from the AKD, the global base mode parameter access can
be used (see PROFIdrive chapter 8.6). The parameter manager is accessed through Slot 1
and a non real time channel needs to be used for this purpose. The AKD supports the record
data 47, which is used to address the Parameter numbers (PNUs).
Base mode parameter access shows the construction of the telegram:
