  1. Use a web browser to log on to the network engine's UI.
  2. Select the field point from the Network tree.
  3. Click the Hardware tab.
  4. Click the link in the Vendor Configuration Data field to modify the parameters shown in the following table.
    Table 1. Field point parameters




    Represents the internal point type, which is fixed to 0 (a group point).


    Represents the group address. It has the standard format <Main>/<Middle>/<Sub-group>.


    Represents the group value type, which is a specific enumeration set used only by this integration. The value of this parameter is the Vendor Configuration Data number that corresponds with the EIS (EIB Interworking Standard) or DPT (Data Point Type) listed in Table 1. See Group value format for more details.


    Represents a list of options. Each character (U and P) represents a specific option:
    • U represents Startup Update; 0 is disabled and 1 is enabled. If set to 1, a Read Group Value request is sent at startup in order to have a real value on the Metasys system. It updates the point only if a read request is enabled for this group address. If no read request is enabled, the data point becomes reliable after a change of value is received.
    • P is not used in this integration.


    Represents the special handler to apply for this value. Possible values are:

    • 0: NONE. No special handler is applied. For example, Metasys value is treated as an Unsigned Byte raw value of 0 to 255 for data point type (DPT) 5.010.
    • 1: DIMMING. Metasys value is treated as an Unsigned Byte percentage value of 0 to 100. Available in both Read and Write mode.
    • 2: ANGLE. Metasys value is treated as an Unsigned Byte degree value of 0 to 360, while raw value is still 0 to 255. Available in both Read and Write mode.
    • 3: BITMASK. Metasys value is treated as Unsigned 16 bit mask; it is filtered by using parameter 6. Available in Read mode only.


    Represents the mask of bits used to filter the value read from the field. This parameter is only valid if parameter 5 is set to 3.

    Format this parameter as 16 digits (comprised only of 0 or 1) which represent all bits of the word used to filter the received value. For example, you have a raw value of 0x01E1. If you set the parameter to value 0000000011110000, you extract only bits 4 to 7 from the received value of the entire word, making the point's present value 0x0E (14).

    This special handler supports only consecutive bits and not mixed bits (for example, 0000000011010000 is not processed successfully.)
