How can you have a tag of the S7 data type IEC time (TIME) displayed in WinCC?

An S7 tag of the data type IEC time (TIME) is a signed 32-bit value that contains a time stamp in milliseconds.

It is useful to have suitable data preparation to display this data type. The following instructions take the example of how to convert a tag of the data type IEC time into a character string in order to display the value with a WinCC text field entitled "Static Text".

1. Creating an external tag in the WinCC Tag Management
In the WinCC Tag Management you create an external tag of the data type "Unsigned 32-bit value". Fill in the fields for the address description of the S7 controller.

2. Dynamizing the "Fill Pattern Color" property of the static text
Create an object of the type "Static Text" in a WinCC picture. Dynamize the property "Fill Pattern Color" with the tag created in Step 1.

3. Dynamize the event "Fill Pattern Color > Change" of the static text

Open the dialog to dynamize the event "Property Topics > Colors > Fill Pattern Color > Change" of the static text with a C action.

Import the downloaded C function. Fig. 04 shows the "Import action" button.

Notes:
This example is structured so that no direct access to a WinCC tag can be made in the C function. If several displays of this type have to be shown in WinCC pictures, the object dynamized in this way can be copied. Then all you have to do is replace the tag with a new one in the dynamization of the "Fill Pattern Color" property. It is no longer necessary to edit the C script.
In a project it might be useful for the purpose of central changing to store the C action from Fig. 05 in a project function.

How do you incorporate a tag of the data type S5TIME in WinCC?
The data type S5TIME is stored in the binary code decimal format (BCD) whereby the associated time base is bit coded. Direct access to this data type is not possible in WinCC.

An S7 tag of the data type S5TIME is a 16-bit value. Bits 0 to 11 represent the time value in BCD format. Bits 12 and 13 represent the time base in bit code. Bits 14 and 15 are not used.

Access to this data type is only possible via a script in WinCC. Different VB scripts are used respectively for reading and writing the S5TIME tag.

Read access

The value of the S5TIME tag is read out of the controller and processed in WinCC. You then get a display of the time value in hours, minutes, seconds and milliseconds.

Define four tags of the "Integer" type ("HH", "MM", "SS" and "MS", for example) without controller connection.
Link these tags to four output fields for displaying the time value in hours, minutes, seconds or milliseconds.
Define a tag of the "WORD" type ("S5T", for example) with controller connection, which receives the "S5TIME" value from the controller.
Link the VB script to the call of an event (a button, for example).

Write access

In WinCC there is input in hours, minutes, seconds and milliseconds. This input is then converted so that the value can be used as S5TIME to supply a timer in the controller.

Define four tags of the "Integer" type ("HH", "MM", "SS" and "MS", for example) without controller connection.
Link these tags to four input fields into which you can input the values for hours, minutes, seconds or milliseconds.
Define a tag of the "WORD" type ("S5T", for example) with controller connection. This is the "S5TIME" value for supplying the timer in the controller.
Link the VB script to the call of an event (a button, for example).
