Solution:

If the tag is an array or a class(or both), every element and member is shared. You should only put the tag name in the Tag Name field, without specifying the index or class member. If you specify an index or a class, the TCP/IP Clinet module will ignore it. Warning: If you need to share an array, then the tag in the server should contain the same number of elements of the tag in the client. If the tag is a class, then the class definition should be the same in both server and client applications. If you don't follow these rules, unpredictable results may happen. .
