Also if it might help, there is no "END" in the log file. Motor PS, I am using the code from the datalogging example s7-1200_datalogging etc downloaded from this website.

You only get one scan to read the done bit.

Motor-Mike Posts: 2 Rating: (0)	I found the problem, I had based my project the original Datalogging example project and upgraded it from version 11 to version12 without checking if it worked. It does not. Datalogging example V11 upgrade-> V12 -> Wrote my own additional code. So it appers that something is broken in the upgrade process. I rewrote my entire program from scratch without using any libraries or imported code starting with a new blank version 12 project. It works perfectly. I went back and tested the original V11 project with version 11, works great. then upgraded it to v12 downloaded it to the same processor, hangs.
