If users want to create an Ether Link shown below,they have to create a data exchange table for the two data request nodes AH-01 and AH-02.(a) AH-01 reads the data in D100~D109 in AH-02, and stores the data in D0~D9 in itself.(b) AH-02 reads the data in D200~D219 in AH-01, and stores the data in D110~D129 in itself.An Ether Link is based on a network. If a node is connected to several networks, users can set several groupsof parameters related to Ether Links for the networks. As a result, there may be several groups of parametersrelated to Ether Links in a PLC. Owing to the fact that an Ether Link is not a master/slave model, each node in anetwork can be a data demanding node and a data supply node at the same time. In the first piece of data inthe table above, AH-01 is a data requiring node, and AH-02 is a data providing node. In the second piece ofdata in the table above, AH-01 is a data providing node, and AH-02 is a data requiring node.11.2.2.2 Opening the Ether Link Configuration WindowBefore users construct an Ether Link, they have to make sure that a network is set correctly. There are threeways to open the Ether Link Configuration window. Method 1After the users select a network, they have to click Construct Ether Link on the Tools menu, or onthe toolbar.
