As far as I can see I cannot use the Read System Time because it is in DTL, I need to read only the system Time as I need to run the program everyday. In the manaull I can only see options to Read in DTL format, I need to read the time in Time format. I would appreciate any help. Thanks and regards

DTL is a struct with each element individually separete (as int): year, month, day, hour, minute, sencond,etc. So you read the DTL but just compare the hour, for example: 1 "MyTime" is defined as DTL 2 In the program you can check if the time is 8h with the block compare and the argument MyTime.hour = 8

jjh5791 Posts: 11 Rating: (3)	Hi Bosbreker, Are you currently comparing your DTL Hour value to a USInt variable?It does need to be a USInt specifically to match the DTL.HOUR data type. Hope that helps!
