In the figure below, the dotted frame indicates that node 1 on the node list is selected, and the gray ground
indicates that node 2 is a data supply node. Node 2 can not be selected, and the information in the M block in
node 2 indicates the data which will be supplied to node 1. Owing to the fact that node 3 does not supply any
data to node 1, node 3 is not displayed in the display area.
The numbers at the left side of the D block in node 1 indicates that the data demanded of node 2 will be stored
in D500~D509 in node 1. <1> in the M block in node 2 indicates that the data in M1000~M1129 in node 2 will be
supplied to 1.
If a specific node on the node list is selected, the node in the display area will be selected. After the users select
All Nodes on the node list, they can click the information about a node in the display area if they want to select
the node. If the users click a device block in a node, the node will not be selected. After a node is selected, a
dotted frame will appear.
Once a node is selected, the node will be designated as a data demanding node. After the users click a device
block in the node selected, a blue cursor will appear. After the users click a device block in another node (a data
supply node), a green cursor will appear. The users can only click a device block in a data supply node. They
can not select the node, otherwise the node will be designated as a data demanding node.
The users can click to add a new piece of data to the data exchange table. The data includes the data
demanding node, the node number assigned to the data demanding node, the data supply node, the node
number assigned to the data supply node, and the device types selected. The users can refer to section 16.4.3,
