16AC30 Series LINKnet Product Manual HA474739U001Chapter 3 - Initial Set-upIP addressing informationEach LINKnet module must have a unique IP address. Each LINKnet module has a uniquedefault IP shipping address of 192.168.1.xxx. The last 3 digits will be random for each Modulein the range of 1 - 127. When the LINKnet module is powered up in a system and it has thedefault shipping configuration, it will self-assign a unique address on each LINKnet Module asdescribed above, with a subnet Mask of 255.255.254.0At this point DSE can be launched and all of the LINKnet modules will appear in the ModuleList.In a LINKnet configuration there is a System Control block which contains a place to set the IPaddress. If no IP address is entered, the default shipping address of 192.168.1.xxx will be usedand the TB will be self-assigned an IP address in the range of 192.168.1 and the last octave willbe in the range of 127 – 1. Counting down.If an IP Address is entered in the System Control block, it will override the self-assigned IPaddress. (if possible)If there is a duplicate IP Address, the LINKnet will self-assign the modules in the range of192.168.1 and the last octave will be in the range of 128 to 199.It is recommended that an IP Address be assigned to each LINKnet module. It is recommendedthat the LINKnet configuration address be used as the last 3 digits of the IP address. Thus, ifthe configuration address is 10 the IP address would be 192.168.1.10When using 3rd party Remote I/O and PLC’s, it is recommended to use an IP Address in therange of .200 to .254 All nodes must be on the same subnet mask.Summary of IP address’s for 192.168.1.xxxwhere xxx = 1 – 127. Self-assigned by LINKnet and assigned by the user.where xxx = 128 – 199. Self-assigned by LINKnet if there are duplicate address.where xxx = 200 – 254.
