6 6 Description 2 Description 3 Components Radio telegrams can be received from sensors, which are based on EnOcean technology, using the EnOcean radio receiver from the WAGO-I/O- SYSTEM 750. This manual describes the connection of a 2-channel PEHA Easyclick wall sensor to the WAGO-I/O-SYSTEM using the WAGO-I/O-PRO programming software.

Depending on the fieldbus controller used, two options are available. For this, connection is made to the service interface of the fieldbus controller using the communication cable For this, connection is made to the service interface of the fieldbus controller using the communication cable Ethernet fieldbus controllers also offer the option to establish the connection via the Ethernet interface.

8 8 Connecting a 2-channel PEHA Easyclick sensor 5 Connecting a 2-channel PEHA Easyclick sensor 5.1 Task 5.2 Program The telegrams from a 2-channel PEHA Easyclick wall sensor are to be evaluated with the help of the WAGO-I/O-SYSTEM. To do this, the PEHA sensor must be installed within receiving range of the WAGO EnOcean radio receiver. A teach-in process with the WAGO radio receiver is not necessary. Discrimination between the individual radio sensors is carried out in the application program. The programming for evaluating radio telegrams in the WAGO-I/O-SYSTEM is described below. Figures 5.1 to 5.3 show the basic structure for programming an application with the EnOcean radio receiver. A prerequisite for communicating with the EnOcean radio receiver terminal is the FbEnoceanReceive function module (Fig. 5.1). The controller recognizes the plugged Enocean modules on its own and counts them one after the other, starting from the left. To address the function block to the proper Enocean module, the corresponding module index must be entered as a constant. Any further EnOcean function modules in the program can only be used in conjunction with the FbEnoceanReceive module. The modules are synchronised by means of the "typenocean" variable structure, which is provided as an input on all modules in the EnOcean library (Enocean_04.lib). Fig. 5.1: FbEnocean_Receive module

9 Connecting a 2-channel PEHA Easyclick sensor 9 The "FbShow_ID_By_Click" module (Fig. 5.2) is used to determine the sensor transmitter ID. In this example program, the "SEL" operator is only used as an auxiliary function for the visualisation system (Fig. 5.4) to enable the transmitter ID that is read in to be stored in the controller. Normally, the sensor transmitter ID is entered as a constant at the input of function modules. Fig. 5.2: Determining the transmitter ID Note Transmitter IDs are normally specified by the sensor manufacturers in hexadecimal notation. Hexadecimal numbers are entered in the WAGO-I/O- PRO software by entering the base followed by a hash sign. (Example: 16#4525AA6E) The FbButton_2_Channel function module (Fig. 5.3) has the task of converting radio telegrams from individual touch sensors with EnOcean radio technology into Boolean output signals. In our example, these output signals are linked to the addresses of the first digital output terminal ( ). Fig. 5.3: Evaluation of radio telegrams from PEHA sensing devices

10 10 Connecting a 2-channel PEHA Easyclick sensor 5.3 Commissioning After the program has been loaded into the controller, the function of the application can be checked. This is done by setting up a simple visualisation interface with the WAGO-I/O-PRO software. Each sensor has a unique transmitter ID, which enables it to identify the sender of a radio telegram. The visualisation is used to assign the received transmitter ID on the FbButton_2_Channel function module. When the button is pressed, a number appears in the line "Received ID number". This number corresponds to the transmitter ID of the button pressed. The ID can then be assigned to the input of the function module by pressing the "LEARN" button. The learned ID number is displayed in the line "Learned ID number". When the assignment has been made, then each subsequent press of the button will be shown in the visualisation by a colour change in the rocker.
