mak Posts: 13 Rating: (0)	Hi all, i am using CPU317F. I want to log the data of DB's within 1 scan. because my certain data is very critical. & that values gettiing high/low for 1 scan only. Those data i could not able to log in WinCC 6.0 SP4. So iam looking for data logger which logs the event within one cycle scan of CPU. Regards

You can use BSEND toemulate an AR_SENDand fool WinCC by adding the required (AR_SEND)header to BSEND packet. Then in WinCC you can use the same Process Controlled Archive as you were using Archive raw tag but use BSEND raw tag.A possible scenario is to read process values every cycle in the PLC (>10ms cycle depend also on the AI channel integration time!) and store them into a circular DB buffer. When you detect a critical condition to log your values you scheduler a BSEND job, format SD_1 based on WinCC documentation for Process Controlled Archive formats and add the AR_SEND header. Drop me a line if you need the AR_SEND header info. I have done such application @ 10ms archive speed and S7-300 for QA signal processing. Dec

Use CFC for easy program FB block. In WinCC create BSEND raw tags on the channel connection(check Send/receive raw db and match cres). If you need to fill time stamp in WinCC make a global action on raw tag change andfill DT - UTC.Copy all toan internal Archive Raw tag and configure TagLogging on this tag.

Carlos_Mdza_Arg Posts: 5 Rating: (0)	Dec I am testing your aplición AR_BSEND.zip and I have a problem. I made a small change in FB2 in all lines with "Unit_Current: WORD: = W # 16 # 0103" for this new line "Unit_Current: WORD: = W # 16 # 0003" I get the RAW data in WinCC Tag (V7), but no data is stored in the files concerned. The configuration files are: AR_ID =1 AR_ID-SUB = 1 and AR_ID =1 AR_ID-SUB = 2 What can be the source of the problem?

Carlos_Mdza_Arg Posts: 5 Rating: (0)	Dec, I found the problem, the change I made is wrong, "Unit_Current: WORD: = W # 16 # 0103" includes Unit (Type) and Unit (Area). AR_BSEND.zip application is working very well. Now my question is: Where I can find detailed information about the headers S7RDARHDS and S7RDHDS? Thank you very much. Regards.

It's been some time. Now you can even use WinAC-RTX 2009 that supports AR_SEND. Dec

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 (138 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.
