FIGURE 38 - IP ADDRESS CONFIGURATION EXAMPLE
Please Note: The ConveyLinx IP address structure is designed such that all ConveyLinx last octet (DDD) of their
address is greater than or equal to 20 and less than or equal to 240. This leaves 36 spare valid addresses (256 –
220 = 36) on the same Subnet for other devices such as PC's and PLC's. In our example, the last Octet for the PC's
I.P. address is arbitrarily set to 10. This value could be any value from 0 to 19 or 241 to 255. Network conventions
are such that on a given Subnet the last octet (DDD) values of 0 and 1 are usually reserved for the Default Gateway
which is often the address of an Ethernet router.
Also note that our example is utilizing all the possible Subnets for the Subnet Mask (255.255.252.0) shown. From
Figure 37 above; we could have selected any of the values for X on the chart that was listed above the 252 value.
In these cases there would simply be more Subnets available to address.
