4 2 Introduction ABB is manufacturer of AC500 PLCs for process and manufacturing autoimmunization as well as from KNX components for building autoimmunization. In projects in which the two autoimmunization systems meet together our customers request a combination and communication possibility of both systems. Examples: Visualization of a plant (e.g. a photovoltaic plant) that is controlled with AC500 on the KNX Comfort Panel. ON/OFF switching of loads at KNX from AC500 side and/or the other way round. Exchange of sensor/actuator states and values. Once recorded information can be used by both systems. The AC500 delivers e.g. KNX values, which it had been recorded via a field bus (M-Bus, Profibus, CAN, etc.). Enlargement of the KNX system with new capabilities. On basis of a AC500 in stock and one specific application program on SD card a "special KNX device" can be generated, e.g. for data exchange with a M-Bus device. 2.1 Used components and tools The components and tools can be extracted from the zip file KNX_AC500_Demo1_App.zip.

The IP router forms the line 6 and has a physical address On the line 6 there are four KNX devices. All these are in field 1 of a KNX topology. The AC500 forms in this example the line 5 and has a physical address and is in field 1. Application Example AC500/Issue:

7 A PC is needed only for the project planning- and test tools. ETS3 for projecting and planning the KNXnetwork via serial interface USB/S1.1 USB. PS501 for programming the AC500 PLC via Ethernet. The KNX Ethernet network and AC500 ethernet network are linked together by a switch. The IP router has an IP-address of , The AC500 PLC has an IP-address of The Notebook/PC has an IP-address of Projected functions (see configuration of the ETS3 project): Function on 4f switch panel: By pressing the first two upper left buttons of the 4f switch panel, a 1-bit switch on instruction will be sent to the AC500 PLC. The AC500 PLC interprets this switch instruction and switches on the corresponding digital output D0 and D1. By pressing the two first upper right buttons of the 4f switch panel, a 1-bit switch off instruction will be sent to the AC500 PLC. The AC500 PLC interprets this switch instruction and switches off the corresponding digital output D0 and D1. By pressing the two lower left buttons of the 4f switch panel, a 1-bit switch on instruction will be sent to the switch actuator SA/S This instruction switches on the corresponding channel C or D. This is a normal KNX functions without influence of the AC500. By pressing the two lower right buttons of the 4f switch panel, a 1-bit switch off instruction will be sent to the switch actuator SA/S This instruction switches off the corresponding channel C or D. This is a normal KNX functions without influence of the AC500. Functions on digital inputs (DI0-DI5) of AC500 PLC: The digital inputs DI0 till DI3 switch the LEDs on/off the 4f-Switch panel. The 1-bit switching on/off instruction will be sent by AC500 PLC. By activating the digital input DI4 will sent 1-bit switching on/off instruction to the channel E of actuator SA/S By switching the input DI4 of the AC500 the switch actuator channel E is switched. The switch actuator channel E sends its status back to the AC500. The AC500 displays the status on the digital output DO4. By activating the digital input DI5 will send 1-bit switching on/off instruction to the channel A of actuator SA/S This will then switch a light bulb which is connected to the channel A. When the switch actuator channel A is active, then a light bulb will be switched on. The actuator sends the actual current value of the load (here the light bulb) on channel A to the AC500 PLC. The value will be displayed in as a variable in codesys program. Application Example AC500/Issue:

9 The physical address of all devices are as in the figure below: Addressing the KNX Device Before programming the KNX devices, each of the device's physical address must be set. Here the addressing of IPR/S2.1 router will be shown. The setting for the other devices follows the same steps. Right click on the device and go to Download. In the Download window, select Program Individual Address. Application Example AC500/Issue:

10 Press the programming button. The Button can be found on the device itself. The button must be pressed in order for the addressing to take into effect Configuration of the KNXnet/IP router IPR/S2.1 in ETS3 The KNXnet/IP router IPR/S2.1 has the special feature, which is it supports "Unicast" communication. At this moment ( ) only ABB IPR/S2.1 supports this form of communication. This communication form is not a standard communication form for KNXnet/IP standard which is "Multicast". The AC500 does not support at this time ( ) "Multicast", therefore the router IPR/S2.1 is necessary. It must be noted, that after the changeover of the IP communication to Unicast, the router IPR/S2.1 can not be used as ETS3 programming interface. Therefore a USB interface or an extra IPR/S2.1 router is needed. In this application note, the ETS3 project has been preconfigured specific for this application. No extra parameterisation needed. to parameterise the router go to: IPR/S2.1 IP-Router,MDRC ->Edit Parameters Application Example AC500/Issue:
