DatalogWrite write only 131 lines

Would you kindly show the logic used to create the datalog and also to perform the datalog write?  Uploaded screenshot would be really helpful.

Hello, I have a problem with datalogging. Logging works well, up to line 131 then writes previously written. I am using S7-1200 1212C, memory card 4MB TIAv16 parameter RECORDS is 1000. Thank you for any idea.

What controls M_WriteEnable (M4.2)?  Oh I see what enables it.  What resets it?

Is there logic for closing the "previous" datalog before creating a new one? 

Did you reference the F1-help showing a datalog example?  It shows exactly how to handle each situation that happens during datalogging.

Start with the provided example, renaming DBs / tags to match what you are using, and then see if all the problems go away.

From what I see in the datalogging program example in F1-Help, you should be using the newfile option when creating a new datalog.  It states in the network comments to use that when a new logfile is to be used. Otherwise it says, the old data gets overwritten.
