24 5 QUICK START GUIDE page 24 Figure 23: Collector and Meter device Now the "wmbs_demo.xml" is loaded. In the configuration suite tree, the "Electricity Meter" meter is located in the subtree of the "Data Collector". This means, that the "Electricity Meter" meter is assigned to the Wireless M-Bus network of the "Data Collector". 5.2 Collector short description The collector parameters can be displayed by double clicking on the "Data Collector" in the navigation tree. By default, it has a device address and an encryption key. There are several options in the "Collector configuration" window, which are grouped in different sections. These sections (e.g. "Collector operations" or "Collector details") can be expanded individually (refer to figure 24 - red framed window in the "Collectors operations" section). The red framed window in the section "Collectors meter list" in figure 24 shows the meter devices, which are associated with this collector. In this case it is the "Electricity Meter" device.

25 5 QUICK START GUIDE page 25 Figure 24: Collector editor If the "Electricity Meter" device is selected in the red framed window, the corresponding parameters such as device address etc. are displayed. It has a unique device address, an encryption key and the address of the collector device. Note, that the collector device address must be consistent with the parameters of the "Data Collector" device. Otherwise no communication will be possible. The well defined configuration of the "Electricity Meter" meter and the "Data Collector" will be displayed with the icon of the "Electricity Meter" in the navigation tree. A well defined connection is displayed with the icon in figure 25, otherwise figure 26 notifies the user that the meter is not connected.

The RSSI value is displayed in a diagram, shown in figure 40.

33 5 QUICK START GUIDE page 33 Figure 40: "Data Collector" Window You can also send a string from the "Electricity Meter" meter to the "Data Collector" collector. Input a message in the text field and press "Send data". The "Data Collector" will receive and display this message as shown in figure 41.

34 5 QUICK START GUIDE page 34 Figure 41: Send data test Another test which you can perform is the "RF-Test". Configure the transmission delay and press "Run RF-Test" on the "Electricity Meter". The "Electricity Meter" will send a standard message to the "Data Collector" periodically. You can now use the Wireless M-Bus Suite to view the "Electricity Meter" which is sending data, and the "Data Collector", which is receiving data. This demonstration Wireless M-Bus network represents a star-network in an area with different device roles. Generally, the collector device is not intended to send custom data to a meter device.

35 5 QUICK START GUIDE page Communication example Figure 42: Communication example Figure 42 shows how a telegram is created and send with a Wireless M-Bus collector device: 1. The command create telegram creates a telegram on the collector device. 2. The collector responds with the id of the created telegram. In this case the telegram has the id=0. 3. The command set data to telegram 0 sets the data of the telegram 0 as byte stream. 4. If the data were set correctly, the collector device answers with a data were set command. 5. The command send telegram 0 will send the telegram with Wireless M-Bus to the meter device. The collector responds with an telegram sent command. 6. If the telegram transmission was successful, the meter device answers with a M-Bus OK message. 7. If the telegram transmission was not successful, a timeout will occur at the collector device. Please note, that according to the M-Bus standard, the response can be delayed by several minutes.

36 5 QUICK START GUIDE page Firmware upload This chapter describes how to upload a firmware to a Wireless M-Bus device with Wireless M-Bus Suite. This feature of Wireless M-Bus Suite allows to upload a firmware update of the Wireless M-Bus application to your Wireless M-Bus device without a debug adapter or a compiler. A bootloader is a program in the microcontroller which is able to receive and update a new firmware to the microcontroller. Therefore no flash programmer or compiler is needed to update the software of the device. Figure 43 shows the basic principle. After the upload, the microcontroller contains the bootloader software and the new firmware. If the microcontroller contains already a firmware (besides the bootloader) and a new firmware upload is started, the bootloader overwrites the old firmware with the new firmware. Figure 43: Update firmware with bootloader Requirements: (a) The Wireless M-Bus device which will be updated with a new firmware must be programmed with the bootloader software. (b) A valid connection of the Wireless M-Bus device to the PC. (c) Wireless M-Bus Suite. (d) A valid firmware file for upload. Please refere to the setup section of your specific Wireless M-Bus device for instructions to perform the steps (a) and (b). Perform the following steps to upload the new Wireless M-Bus firmware: (1) Open Wireless M-Bus Suite. (2) Select Cancel to close the start-up window as shown in figure 44.

39 5 QUICK START GUIDE page 39 Figure 49: Firmware upload in progress (13) When the firmware upload is finished, a message box pops up as shown in figure 50. It is possible to cancel the firmware upload with the button Cancel. Please note, that if the upload is cancelled during the firmware uploading process, no valid firmware is available on the Wireless M-Bus device. It is not recommend to disconnect the Wireless M-Bus device from the PC during the firmware upload. However, in both cases, it is still possible to upload another firmware. Just start the firmware upload again with the desired firmware. Figure 50: Firmware upload finished (14) Press Next or Finish. If the Next button is pressed, a summary of the firmware upload will be displayed on the next window. If Finish is pressed, the wizard will be closed. (15) After the firmware upload is finished, the Wireless M-Bus device restarts and executes the new firmware. Please note, that the configuration of the device will be reset by a firmware upload. (16) Now a project can be loaded to configure the Wireless M-Bus device, e.g. the Demo Project which is provided by Wireless M-Bus Suite.
