Chapter 16 Network Configuration and Data Exchange<br />

16.4.4 Node List and Display Area<br />

If users click All Nodes on the node list, all the nodes will be displayed in the display area, and all<br />

the data exchange groups set will be in the data exchange table under the display area. Besides,<br />

the devices in which the data demanded will be stored, and the data supply nodes are indicated in<br />

device blocks of the nodes in the display area.<br />

>2< in the D block in node 1 indicates that the D block demands data of node 2, and the numbers at<br />

the left side of the D block indicate that the data demanded of node 2 will be stored in D500~D509 in<br />

node 1. Likewise, >1< in the D block in node 2 indicates that the D block demands data of node 1,<br />

and the numbers at the left side of the D block indicate that the data demanded of node 1 will be<br />

stored in D1000~D1019 in node 1.<br />

If the users click a specific node on the node list, the node and the nodes of which the node<br />

demands data will be shown in the display area, and the data in the data exchange table under the<br />

display will be related to the specific node selected.<br />

In the figure below, the dotted frame indicates that node 1 on the node list is selected, and the gray<br />

ground indicates that node 2 is a data supply node. Node 2 can not be selected, and the information<br />

in the M block in node 2 indicates the data which will be supplied to node 1. Owing to the fact that<br />

node 3 does not supply any data to node 1, node 3 is not displayed in the display area.<br />

The numbers at the left side of the D block in node 1 indicates that the data demanded of node 2 will<br />

be stored in D500~D509 in node 1. in the M block in node 2 indicates that the data in<br />

M1000~M1129 in node 2 will be supplied to 1.<br />
