CHAPTER 11
Routing Table Component
Routing tables allow networked PLCs to be configured so that they can communicate with each other via
gateways; across remote networks. The routing tables contain the network, unit number information required.
It is only necessary to set up routing tables if the end connection PLC is not a direct connection, i.e. using
another PLC as a gateway connection. The routing table is held within the PLC(s) which acts as the gateway
device. Different types of PLC and networks have different capabilities for routing.

The
Routing Table
menus are accessed from the PLC Network Configuration Tool dialogue and contain options
allowing the editing and setup of routing tables both offline and online. The routing tables which are being
used in a network, can be viewed online.
Different online Routing Table Setup dialogues are used, depending upon the protocol associated with the
routing table. The way in which they are displayed and operate is similar in each case.
The PLC Network Configuration Tool dialogue, visually displays the structure of the routing table associated
with the PLC (including the destination node and network gateway employed in directing data across the
network). Initially the visual representation of the routing table is empty, or set to zero, until a routing table file
has been opened. An overview of the routing table can also be viewed and edited in a graphical or tabular
format.
