Now for internal use only V0.4

set up variables on PLC and give them HMI_Tag :

       |---global    
          |-A (DWORD)
          |-B (TIME)
          |-C (BOOL)
          |-F (LINT)
          |---MainInstance
             |-Value1 (INT)
             |-Value2 (REAL)
             |-Value3 (STRING)

Run RESTdemo.py

output:

If there is no variable called 'AAA',you will see the following message
	invalidNames
Here we can get the variables' type of group
组成内成员数据类型：
	{'A': 'DWORD', 'B': 'TIME', 'C': 'BOOL'}
