The data in the log is fine but I have had 2 instances where when I try and download the log file from the web page, it seems as if it is hung in a loop and never finds the end of file. I have allowed it to continue downloading where the file size shows over 10MB. Knowing that a single log file can have a maximum size of 500KB, and that the PLC doesnt have this much memory on board is why I think the plc is hung in a loop. The only way to correct the problem is to delete the log file and let it start logging again. I am using a 1214C AC/DC/RELAY with firmware rev 2.0.2. I realize this isnt the latest firmware, however the customer has several plc's running this firmware and it will be a pain to update the firmware on all locations. I am using Step7 V11 SP2.

I realize this isnt the latest firmware, however the customer has several plc's running this firmware and it will be a pain to update the firmware on all locations. I am using Step7 V11 SP2. I do not know what data log bugs were fixed between firmware revisions 2.0.2 and 2.2, but I would guess at least 1 bug fixed was the one you describe. For something where you cannot update the firmware, it would be better to create a support request and find out if you must upgrade the firmware to fix the problem, or if a workaround exists. If it were me, I would push back with the customer for any PLCs that are running 2.0 (a fairly buggy firmware if you ask me) and suggest for any of the s7-1200 projects using the web data logging, upgrading the firmware, and also update the plc hardware device configuration to match the firmware change is essential for the long term performance and support. If it has PIDs or special functions, the project software should also have a compile rebuild all. Post your results!
