I edited TV value DB100.DBW20 as s5time in symbol table.The problem is in order to create a simatic timer tag,your tag must be a doubleword.But db100.dbw20 is only a word. I tried to create a tag with one word referencing db100.dbw20 but I could not succeed.Becaue if I writesome numbers to that tag , the timer value(db100.dbw20) changes unproportionaly.Please have alook.Thanks.

By selecting "DwordToSimaticBCDTimer" for "Adapt format" the time value is converted from the S5TIME format into an unsigned 32-bit value. The content of the WinCC tag corresponds to the time duration in milliseconds. For input values, some rules apply. 10 msec is a minimum. Between 10 and 9990 msec, you must round up to the next multiple of 10 msec. Between 10 sec and 99,9 sec, you must round up to the next multiple of 100 msec Between 100 sec and 999 sec, you must round up to the next multiple of 1000 msec = 1 sec

The TV input must be s5time format(single word),but wincc s5timer tag occupies double word.You can not choose "adapt format-simatictimer"when the tag occupies single word.So how can I change S7 timer TV input value from an I/O field in Wincc6.2Thanks alot.
