Dear sirs.
We have a problem when working with WinCC tags:
We are working with:
WinCC v5.0 SP2
SIMATIC S7
TCP/IP or Industrial Ethernet connection
We have made several operations:
1. Created a tag 'D30024_Status', Unsigned 16-bit, DB30, DW108
2. Created a structure 'DTest' with 1 WORD tag.
3. Created a tag 'D30024' of type 'DTest'
(As a result we have a tag 'D30024.Status', Unsigned 16-bit, DB30,
DW108)
Now we have 2 tags , both connected to the same address.
The first one we can read and write properly, but the second (in the structure) doesn't refresh its value:
If we write into 'D30024.Status', then we see the value in 'D30024_Status',
If we write into 'D30024_Status', the value in PLC changes, but the 'D30024.Status' stays unchanged.
We have tryed the situation on several PCs and the result is the same.
Can anybody help ?
