Only 2 tags are communicating other tags show 0.00.

Hai everyone,

An using Wincc Flexible 2008 SP3, i made graphics and assinged tags to inputs in my wincc flexible. Now it is connected to PLC (S7 300, 317 2pn/dp) via ethernet. Initally i faced problem in accessing the data block (it was not declared in the symbol table) later it was declared and tag assignment was finished sucessfully.

after connected to plc and gone to ONLINE, only 2 tags are (from D651 - int type) are communicating other tags show 0.00. (they are from DB415- real : these value are showing in DB block in S7 5.5 sp4 after gone to online)

When disconnected, the tags worked show #### symbol but other tags remain 0.00.

i dont know how to resolve this issue. i tried reconnect option from wincc flexible still no change.

Split from WinCC Runtime - Tags are not displayed.

Your tags with the ###### are connected to your plc. The others are not.

Look at the properties of the working tags compared to the non working.

A cross ref on the tags will show if its connected as it will show the plc location as well as the hmi.
