You have to concatenate the value and units in PLC (convert value to text and add the unit) and pass this "big" tag to WinCC for display. IMO a betterapproach would beto create a customized object in WinCC which is made up of two fields, one value field and other text field. The text field can be a separate variable or if using CFC, simply S7_unit attribute. Hope this is what you were looking for.

You don't have to read it from the PLC directly, it can be done by the script on the I/O field itself. Regards Sydney

Let me know what you think. char szTime[12]; int iValue; iValue = GetTagWord("Value"); sprintf (szTime, "%i m/min ",iValue ); SetPropChar(lpszPictureName, lpszObjectName, "Text", szTime); Attachment NewPdl1.zip (36 Downloads)

But as mentioned by Phantom75 have attention to performance if you have a lot of those fields in one picture. Also have an eye on the FAQ http://support.automation.siemens.com/WW/view/en/7929092
