Greetings dear expert,

I'm currently working with a S7 1200 DC/DC/DC and I have a little issue with one of my pages.

I need to send Time data into the CPU, and after many test I discovered that to be sent, thoses data need to have a special writting. Is there any way to make a conversion function of number into Time before sending the values into the CPU. In that way, I could just write any number and the data will be send into the CPU as a Time type value.

Hello dear experts,

Sorry to bother you but the answer that you gave me is not was I'm looking for. For my page to work, I need to do a special code that will convert a Number input into a Time value that the CPU can understand. After convertion, the value will be sent into the CPU. 

I'm asking this because right now I can send a value into the CPU with my page but it require me to write the data like this : T#5S

Best regards

Hello.

The 'T#5S' is a notation that only has meaning in the Step7 (design environment of the PLC). The notation belongs to the TIME datatype. The description of what the TIME datatype is, has already been linked to.

TIME is a 32-bit signed number that represent a time value measured in milliseconds units. Stating 'T#5S' is in fact stored internally as 5000. You can scale the 5sec to ms and already have what you need. Alternatively send the '5' to the PLC as a DINT (32-bit signed) number and have the PLC convert to TIME:

"timeValue" := // Convert in PLC
DINT_TO_TIME("htmlSeconds" * 1000);

What are your thoughts?.. which way you want to do this?
