Data typ conversion TIME

Reaunald

Hello,

With Tia portal step7 v11 sp2.
Does anybody know how to convert a floating point value or an integer into a time data type.

Hope you can help me out.

Conversion into the TIME data format
Using the advanced instruction "T_CONV" you convert a numerical value of the DINT data type into a time stamp (TIME) and vice versa. You must convert all other data types (INT, REAL, BCD, ...) into the DINT data type before you can convert them into the TIME data type. The "T_CONV" instruction is located in the block editor in the "Advanced Instructions >Date and Time"" palette. Fig. 03 shows an sample conversion of INT and REAL number values into the TIME data format.

Creation environment
The screens in this FAQ response were created with STEP 7 V11.0+SP2.

For S7-300/400 I have written blocks that do convert S5Time<->Int (int in 100ms units i.e. 1234 = 123.4s) - this will give straight conversion.

Also you can use standard block to convert Time --> S5Time

The Time data type is dint in ms so when your time is in seconds multiply it by 1000.
