Timeout time (10 ms)
Trigger byte address

Description
This parameter specifies how long the gateway shall wait after transmitting a broad-
cast transaction before processing the next entry in the scanlist. The value should be
set high enough to allow the slave devices time to finish the handling of the broadcast.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
Note: This setting is only relevant for the Broadcaster node.
This parameter specifies the action to take for this transaction if the higher level net-
work goes offline. This affects the data that is sent to the sub-network.
• Clear - The data destined for the slave-devices is cleared (set to zero)
• Freeze - The data destined for the slave-device is frozen
• NoScanning -The updating of the sub-network is stopped
This parameter specifies the action to take for this transaction if the sub-network goes
offline. This affects the data that is reported to the control system.
• Clear - Data is cleared (0) on the higher level network if the sub-network goes
offline
• Freeze - Data is frozen on the higher level network if the sub-network goes offline
This parameter specifies how long the gateway shall wait before attempting to recon-
nect a disconnected node. A node will be disconnected in case the maximum number
of retries (below) has been reached.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
Note: This setting is not relevant for the Broadcaster node.
This parameter specifies how many times a timeout may occur in sequence before the
node is disconnected.
This parameter specifies how long the gateway will wait for a response from a node. If
this time is exceeded, the gateway will retransmit the Query until the maximum num-
ber of retries (see above) has been reached.
The entered value is multiplied by 10. An entered value of 5 will result in 50 ms.
This parameter specifies the location of the trigger byte in internal memory (only rele-
vant when "Update mode" is set to "Change of state on trigger").
Valid settings range from 0x200 to 0x3FF and 0x400 to 0xFFF
Transactions 30
