I have a problem with historian. I managed to connect successfully zenon with sql database through "RECIEVE" and "SEND" tables. The thing i missed is that if there is new entry in table with different timestamp , but same value "On change" historian does not store that value.  As it is  important for me to store all data that comes from  SQL database, even it is the same value with different timestamp. Any advice how to store all data from SQLDRV to historian without adding aditional values from cyclic scan ?
