I have implemented a little example with your SCL source, and have added also wincc script on button which prepare internal raw tag and allow to do archiving of some internal variables of WinCC. I hope it will be useful for somebody. I use this trick to log data received via simple (without special headers) BSEND from PLC to raw WinCC tag. After that I translate this data to internal tag with spesial formatting for archiving. All it became possible because of your 7 years old post! Attachment Ar_bsend (2).zip (258 Downloads)

The same thing is happening both with Dec's function when I compile it, and also with Amoralis function which is already compiled. I have CFC 8.0, and SCL compiler 5.3 SP6. Any help, please? PS I have a suggestion, this topic should change the name, or to bi splitted to another one, with the name: How to simulate AR_SEND function in CPU300 using BSEND.

I have read WinCC help "Archiving Process Values > Process Values and Tags > Structure of a Telegram with Raw Data Tags", but this structure does not correspond to the program code in your examples. How do you identified right structure of the telegram? How can I reprogram your code for another frame type, for example for Type 2: n measured values of a process tag + date and time of each measured value. Thanks in advance for any help.
