s7 300 timers and esa panels

hi,
i used esa panels with s7 200 before, so i could configure timers but, in s7 300 (as you know) i have to define timer value as (for ex) s5t#2s. i want to modify this 2s value with my esa panel.
which type of data should i declare from esa(word, timer, bcd etc?)

Example:

L DB1.DBW0 (this is tag of time from ESA, it should be HEX/BCD format)
L W#16#1000
OW
SD T10 (if DB1.DBW0 contains 2 then T10 is a 0.2sec on-delay timer)

0000 is for 0.01 sec times
1000 is for 0.1 sec times
2000 is for 1 sec times
3000 is for 10 sec times

thanks, i tried it with the code below. i simulated it with plc sim. but when i try to give the value 10 to the db1.dbw0 (via mw1), the plc goes to stop because of a bcd error.

A M 0.0
L DB1.DBW 0
L W#16#1000
OW
SD T 10

A T 10
= M 0.7

L MW 1
T DB1.DBW 0

Try the following:

L MW 1
ITB
T DB1.DBW 0

thanks.
it worked in simulation. i ll try it with real esa panel.

when declaring a tag as dbw i saw 1/100 sec 1/10sec etc.. can we use them also?
