Note
1. The unit number is set between 00 and 15 using the rotary switch on the front
panel of CV-series and CS1-series Controller Link Units, and is the same as
the operating level for C200HX/HG/HE PCs. For the Support Board, the unit
number is 16 less that the unit address (i.e., the Communications Unit num-
ber) set for the Board in the FinsGateway settings.
2. The network address is the address of the network connected to the Unit
(between 1 and 127). The address is set when the local network table is
created.
A relay network table provides the node and network addresses corresponding
to the initial relay point (first point the data must go to) en route to a target net-
work (end network) not directly connected to the local PC. The table traces the
route from the relay point to the end network.

Data first goes to node

Data then goes to node

We know from the
local network table
that the data goes
through local unit
number 1 to reach
network address 3.
Data goes to node

i.e., the local net-

Setting Routing Tables
This section describes routing table settings.
Routing tables are set through the FinsGateway, Controller Link Support Soft-
ware, or CX-Programmer. This section describes setting procedures and setting
details.
For specific procedures, see the FinsGateway online help, Controller Link Sup-
port Software Operation Manual (W308,) or CX-Programmer User’s Manual.
