It should be string with length say String[16] that means 16 characters can be given. Have you done that. Please check that. I have seen your PDF. Please take a look at the following link https://support.automation.siemens.com/WW/adsearch/resultset.aspx?region=WW&lang=en&netmode=internet&ui=NDAwMDAxNwAA&term=display+date+and+time+as+string+in+wincc&ID=1085941&ehbid=1085941 https://www.automation.siemens.com/tf/WW/en/Posts/9552 In WinCC IO field the property has to be string data type with IO field type as Ouput. Have fun...

It seems that you are trying to use Multi-Instace Faceplate technology, described in APL Style Guide: ^{6.4.8.2 Multi-instance faceplates A multi-instance faceplate is a faceplate that you use to access different block instances in a CFC chart.} So in CFC "RT" the name of the main FB is "2" ? _{You've cut the head off that block..} In that way the second FB RTC_STRING should be named "21" – main FB's name + specific name In the faceplate you should connect variable not as ".Date_Time", but as "1.Date_Time", because the Tag Prefix of your faceplate belongs to the main FB "2" (RT/2***) and you are connecting another Tag from another FB: RT/2 + 1.Date_Time* gives you RT/21.Date_Time

Many Thanks TerminalBuzz. again more, Is main FB's name + specific name is relevant to all data types and all multi-instance faceplace, right? Sorry, i am too much and i will read that APL Style Guide too.

You are right. It's all about playing around with a Prefix Tag of the faceplate and a Tag Name of the WinCC. If the PT is known, it is also possible to display the information of the Shared DB on the faceplate.
