Destination IP-address (DI)
| Function | Defines the IP-address of the destination network host to which the device will attempt to connect to (by default) |
| Set (S) command format | SDIxxx.xxx.xxx.xxx, where xxx.xxx.xxx.xxx is the IP-address of the destination in dot-decimal notation (i.e. 192.168.100.41) |
| Get (G) command format | GDI |
| Initialize (I) command effect | Initialized unconditionally, through network command, or serial command |
| Post-initialization value | 0.0.0.1 |
| Change takes effect | After reboot |
| Relevance conditions | Current Routing Mode (RM) = 1 (server/client) or 2 (client) |
Destination IP-address defines the IP-address of the network host to which the device will attempt to establish an outgoing data connection. Exactly when the device will attempt to establish such a connection is specified by the Connection Mode (CM) setting. Destination port the device will attempt to connect to is specified by the Destination Port Number (DP) setting.
Destination IP-address of 255.255.255.255 means “link-level broadcasts”. This is a special case so the following considerations should be taken into account:
-
When current Transport Protocol (TP) setting is 0 (UDP) the device will be sending out its own UDP datagrams as link-level broadcasts i.e. with destination MAC-address set to 255.255.255.255.255.255. Furthermore, there will be no destination switchover that happens when UDP datagram is received from a network host (therefore, the device will keep sending its datagrams as broadcasts).
-
When current Transport Protocol (TP) setting is 1 (TCP) the device will not attempt to establish an outgoing connection at all. This is because TCP is strictly a point-to-point protocol and does not support broadcasting.
Destination IP-address is irrelevant in the following cases:
- When current Routing Mode (RM) is 0 (server) because the device does not establish outgoing connections in this mode at all.
