Property | Value | Description |
---|---|---|
L Data Worker, Max Queue Size (hidden) | 1, 2, 3 ... max Defaults to 1000 | Defines the size of the Group Data Operation Queue that holds a list of Group Address reads or writes waiting to be started as soon as the comms stack is able.
|
Hop Count (hidden) | 0, 1 , 2 ... 7 (Defaults to 6) | Defines a counter for managing frames. Each communications frame contains a hop count. A frame’s hop count is decremented by the KNXnet/IP Router devices to avoid looping messages. When it becomes zero, the frame is discarded from the KNX network. |
Max Pending Reads | 1, 2, 3 ... 10 (Defaults to 4) | Controls how many concurrently Active Group Address Read Operations are allowed. Active means that a particular operation has reached the head of the Group Data Operation Queue and the Comms.Stack has sent an L_Data_req message to the KNXnet/IP Interface devices and received an L_Data_con reply, but has not yet received a corresponding L_Data_ind message. This limit is intended to prevent the KNX twisted-pair line from being swamped with this driver’s traffic although there is no clear guidance on this in the KNX specifications. |
Read Before Write Timeout | 100ms ... 6secs (Defaults to 0.5 secs) | Defines the amount of time to wait before timing out on a read-before-write. Read Before Write Timeout. |
