a. Response delay is the time, in milliseconds, that the gateway
should wait for a response to a message from a data terminal, or
its connected equipment, to reply to a request.
b. Queue message timeout is the length of time a message will be
queued before timing out when the gateway is busy.
13. In the SCADA area, select the protocol to use and the default port
number to be monitored for communications from all/any data
terminals.
14. In the IP area, enter the range of the IP addresses of the RTUs in
CIDR format, under Remote IP Network. The IP address range
entered should include all IP addresses entered as ‘routable IP
addresses’ in the TD9300 data terminal configuration. If multiple
ranges are required, enter them as a space separated list.
15. Click Save.
16. Select Settings > DMR Site Parameters and click Add.

3.3.4 Setting up the SCADA Gateway for High Availability
1. The different SCADA gateways that need to communicate need to
be added to the Gateways list, including the localhost.
a. Select Network > Gateways and click Add.
b. Enter the Name, an optional Comment and the IP address of this
SCADA gateway and click Save.
c. Repeat steps 1 and 2 for each SCADA gateway in the network.
2. Assign the HA Active IP address and the SCADA gateway HA
Priority.
a. Select Settings > Local Parameters and click Edit.
b. Under the High Availability section enter the assigned Priority
and Active SCADA gateway IP address for this gateway (priority
1 is the highest priority) and click Save.
c. The gateway needs to be rebooted to apply the changes. To reboot
the gateway, connect to it by SSH and login as root (see
Section 4.1 and Section 4.2). Issue the command reboot.
If the SCADA gateway is running on a CentOS DMR node this will also
reboot the DMR node.
