9.2.6 Correct Network Architecture

After users click Check Routing Information on the Edit menu, or on the toolbar, the system will check
whether the network architecture the users create is correct, and the check result will be displayed in the
message display area.
The system checks the ports which are connected to networks. It checks whether the information about the
nodes and the information about the networks are correct. Specifically, it checks the node numbers, the RS-485
station addresses, and the IP addresses in the working area. At first glance, the network architecture in the
figure above seems to be incorrect in that the node number assigned to AH-01 is the same as the node number
assigned to AH-03, the node number assigned to AH-02 is the same as the node number assigned to AH-04,
the RS-485 station address assigned to AH-01 is the same as the RS-485 station address assigned to AH-02,
the RS-485 station address assigned to AH-03 is the same as the RS-485 station address assigned to AH-04,
the IP address assigned to AH-01 is the same as the IP address assigned to AH-03, and the IP address
assigned to AH-02 is the same as the IP address assigned to AH-04. The users can view a network at a time by
means of a skill introduced in section 9.2.5. The users have to make sure that the node number, the RS-485
station address, and the IP address which are assigned to a node are not the same as the node number, the
RS-485 station address, and the IP address which are assigned to another node. The message in the message
display area in the figure above indicates that the network architecture in the working area is correct.
