ISPSoft User Manual
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 16.2.5. 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.
• Node number
In principle, the node number assigned to a node in a network can not be the same as the node
number assigned to another node in the network. If users view a network at a time, they can
