I've been trying to figure out for a long, long time why a DataLog was not being created, when I have a DataLogCreate in my code. Then I ran a trace & the ERROR flag is set. At this point the STATUS code is set to 80B3 Hex, which means "Insufficient memory space on the memory card" (see pic). The thing is, there is no memory card in the slot & previously when the Datalog CSV file was created, it must have been stored in the PLC's internal memory. Is there a way to clear the memory, so that the DataLogCreate works properly? Will MRES (memory reset) free up the PLC's internal memory so that I can create a Data Log? Also, I am worried I will lose my code. Can I reload the project from TIA after doing MRES? Happy to answer any questions you may have. Many thanks in advance. Attachment Trace 2.png (288 Downloads)

	If this information really helps, you could use the Rate function. Best Regards.
