� The AC500 sends a 1-bit switching instruction onto the channel A of the KNX Switch Actuator (SA). This action is entered in the group address 1/2/3. The AC500 has the physical address 1.3.20.

� The SA sends a 1-bit status response back onto the AC500. The digital output D01 of the AC500 is switched. This action is entered in the group address 1/2/4.

• The variables are from type array or structure and declared globally

• These variables are used for data exchange among DPT FBsand Ethernet FBs.

• Recommended length is 31 bytes. Shorter array length may result in lost of information.

• Only minimum 2 arrays needed for data exchange.

� All FBs are declared global

� Function KNX_TOTAL_LEN_Appcalculates the length of the telegram to be sent.

� The target IP address is192.168.3.222. This IP address corresponds to the IP address of the KNX IP router.

� Port: 3671

Potential & Possibility

� Autogeneration of the assigment table, Import/Export of the assigment table and of thevariables to and from PS501/ ETS3.

� Extension of library with ETS4-DPT

� Implementation of Multicast or a tunneling clientin the AC500.

Present possibilities

Extension possibilities

Future

development with support from R&D

� AC500 product file

� Setup of test and demonstration systems

� Larger scale pilot test system

� Setup of test and demo systems for customer

� Integration of M-Bus devices into KNX via AC500

• Unicast communication, KNX router IPR/S2.1

is needed

• AC500 as „KNX device“

• KNX CodeSys library

• Processing of KNXnet/IP datagrams

• Application note
