Siemens S7400 timer value preset help

Hello,
i need some help with attaching a preset timer value to a timer. This is the scenario.

i have a conveyor system that transports 18 different products ( one product run at a time )

Each product, or format has a saved menu consisting of timer values, counters etc. These values are stored in data blocks, 101-118. One for each format.

When the operator selects a format on the touch screen HMI, the saved menu i.e Db101 ( format 1 ) is transfeered into a working menu DB100. All of the saved presets loaded into DB100 are then used within the S7 software.

i wish to add an a new timer value which will be used for all formats. However, each format requires a slightly different timer value.

I want to use one timer ( T50 ) and load the timer value stored in DB100. So, instead of inputing a S5time value i want to input DB100.DBx8.0 I will then assign DB100.DBX8.0 a value and list it in the data block as S5TIME.

Every time i try to input the Db into the TV on the timer it turns red so obviously the syntax is incorrect. Can anyone help?

Thanks.
Jason

The timer value is stored as a word in the datablock so you need to enter DB100.DBW8 for the TV, not DB100.DBX8.0 as you have written.

Thanks Simon,
I had already tried the DW8 but because i hadn't assigned the correct elementary type within the format and working DB's it would not let me insert.

Cheers,
Jason
