  • Page 46: Managing A Network Of Controllers

    Managing a network of controllers The pLAN network (personal Local Area Network) is the name of the physical network that links controllers to remote HMI terminals. The connection of the controllers via the pLAN network allows the datapoints of one controller to be exchanged for another, following the logic set out by the program, i.e.

  • Page 47: Addressing The Plan

    Addressing the pLAN Once the controllers are connected over the pLAN network, the controllers and the terminals must be addressed. There is a range of 32 possible addresses (binary logic). As a result, a total of 32 controllers and terminals can be connected over the pLAN network.

  • Page 48: Assigning Private And Shared Terminals

    If the "setting" field is set to '0', the terminal will use the Point-to-Point Protocol (not the pLAN) to communicate with the controller and the "I/O board address: 07" field will disappear as it will not be necessary. 3.3.2 Assigning private and shared terminals Follow the procedure below if, at this point, it is necessary to change the list of terminals associated with each controller: •...

    5.5.2 Configuration process The manufacturer does not provide a system start-up, configuration, parameter setting or KNX network addressing service. The configuration of this type of network requires the creation of an ETS database. This database may only be used and managed by personnel trained in the use of KNX configuration tools and their associated specifications.

  • Page 59 The plugin Declaring the air handling unit controller in the ETS project requires the use of a plug-in: AHU_plugin_21 for ETS3 AHU_plugin_30 for ETS4 AHU_plugin_ETS5 for ETS5 This plugin is used to allocate the individual addresses for the controllers and to download the table created by KSet, which is the XML file.
  • Page 60 Reopen ETS5 and open the "AHU_plugin_ETS5" project. Copy and paste the plugin model for each device to be included in your project. The address of each device is automatically incremented. If necessary, you can manually change the address of a device in Properties. Assigning the physical address The physical address of the KNX board is assigned using the standard ETS procedure.
  • Page 61 Downloading the XML file You must ensure that: The Bus wire network is drawn out and connected The Bus is powered on The KNX board is connected to the network The controller is powered on On ETS5, use the mouse to select the controller which needs to be configured, select the "Parameter" tab and click "Open the dialogue box for parameters specific to the product".
  • Page 62 NOTE: This procedure is specific to the KNX board and is the only configuration operation permitted by the ETS5 program, other than allocation of the address. The KNX datapoints loaded via this plug-in do not appear in the Group Objects tab. To check and/or modify your group addresses, you need to re-open your xml file from KSet and, once the modifications are complete, upload it via the ETS plugin.
