Hi Krisjan, I have cheked it in my PLC 1212c without MC but doesn't seems that my datalog entries are up to the 25 or limited. I was able to create up to 200( that i checked). If ur using DB OPEN in that check the MODE whether as 0 or 1.[ This is for retain only , still try it] Check the memory usage of ur code or else try the datalog in a very simple program. Use the sample program which was posted in this forum & try how many entries u can enter.... Posting ur code may help to check in our PLC Hope it helps Regards, Nelliyan.G |

Some things to keep in mind, Even you can Log a lot of data (in rows),you have to manage the data type tha you're Loggin, i.e, is not the same 98 Data of "Real" that 98 of "Int" in bytes. The other thing is that CPU only can log 250KB on CPU 1212 (see other references) without MMC AsRenaud Houlesaid if you click on the name is different amount of data that you specify to download. So, downloading the full archive, it's necessary to click on the blue Disk Icon. The other Thing is that you Check the "Status" on the Create block, it tells you if you reached the max. amount of data to create the archive. I've been making some tests, and I can Log 1000 data logs whit 5 columns of "Int" data type And more of them. And the last thing (and very important for me) is that you only can modify the number of records if you reset the block, once created, the archive will let you logg the first "number of records" specified. So if you wanna make a test, every time you'll have to reset the block and then create de Archive with the new number of records. Best regards. |
