#WHAT IS WINCC FLEXIBLE SOFTWARE#

It was not possible to send by properties, because assigning ActiveX property to an internal tag was working one way only. With Internal tags, I was successful to get data from PLC to my ActiveX, however I realised the major problem when I finished developing my ActiveX, and it was not possible to send data from ActiveX to WinCC (so PLC) If you want to send data inside of an ActiveX, you create an internal tag and assign it to the one of the properties of ActiveX. I have found that the only way to use properties of An ActiveX is using вЂInternal TagsвЂ™ of WinCC. Reading or writing a property inside a script directly causes a crash. In WinCC programming manual, it says that it is possible to read and write a property of an ActiveX within a script, but it was not true.

Then I started to add properties one by one, and with the first property of ActiveX caused a crash again. I decided to walk step by step, I realised that WinCC had a really pain about ActiveX, so I have started with a totally empty ActiveX and successfully compiled the WinCC project. Then I tried to code my own ActiveX, embedded SAX Comm object and mapped some properties and events, however result did not changed, WinCC was still crashing. вЂњFatal ERROR: screen item Screen_1 in screen Screen_1 contains inconsistent data and should be deleted.вЂќ Just adding SAX Comm object was enough to crash WinCC development environment.

It was not possible because I could never be able to compile the software even without any script code in it. They already had a WinCC flexible licence and requested the project in WinCC.ДЇirst of all, I could not find a way to use RS232 comm ports with WinCC, so I decided to use SAX Comm library for RS232 communication. Se vera l months ago, a customer requested a product tracing system which should work with SIEMENS PLC.
