NWCONFIG can also carries out communication through routing.
Routing is a function provided by AH500 series CPU modules. It directs packet forwarding. Packet forwarding is
the relaying of packets from their source toward their destination through intermediate nodes. In the figure
below, the device which actually connects to the computer is AH-01. If the computer wants to connect to AH-03,
it can communicate with it through routing, and designates AH-01 as the first station. After the computer sends
a command, the command is transmitted to AH-03 through AH-01 and AH-02.
The important points about routing are listed below.
(a) Users have to create networks in NWCONFIG, and download the routing tables produced to nodes in the
networks. Please refer to section 9.2 for more information.
(b) AH500 series CPU modules support routing whereas DVP series PLCs and other devices do not support
routing. Although DVP series PLCs and other devices can not function as intermediate nodes through
which packets pass, they can function as destinations to which packets are transmitted.

9.1.3.2 Setting Communication Parameters

The steps of setting the communication parameters in NWCONFIG are as follows. Some prerequisites have to
be considered. Please refer to section 2.4 in ISPSoft User Manual for more information
(1) Start the communication manager COMMGR, and then create a driver in COMMGR.
(2) If users want to download parameters to a single device, upload parameters from a single device, or
monitor a single device, they have to make sure that the device specified is the same as the device which
is actually connected to the computer. If the users want to download parameters to multiple devices,
upload parameters from multiple devices, or monitor multiple devices, they have to make sure that the
devices are connected to an Ethernet network, the devices are assigned IP addresses, the IP addresses
actually assigned to the devices are the same as the IP addresses set in NWCONFIG, and the networks
actually created are the same as the networks created in NWCONFIG.
(3) Click Communication Setting on the Tools menu or
After the users complete the setting described below, they can click OK in the Select a Driver window.
