esamson Posted January 29, 2015 Report Share Posted January 29, 2015 Hello , I try to save the values on an SD card into an Excel spreadsheet and I want these valaurs be associated with the date and time of recording .I know he must use the block ' RTC to ASCII ' . except for the date it works well , but for now not at all, and I do not understand why. I enclose my blocks. When I record my values MI150 MI151 = time = date and MI100 = value , I get a time that is written 1129/01/15 , which does not correspond at all to an hour hh: mm: ss Thank rtc to ascii.bmp Quote Link to comment Share on other sites More sharing options...
Eyal Koren Posted January 29, 2015 Report Share Posted January 29, 2015 Hi, As you probably know, ASCII is protocol for characters representation. Every character is stored in one byte of data. In visilogic, ASCII strings are stored to MI's, hence two characters in a single MI. For a full date to be represented, you need to store 9 characters (8 for the actual date + NULL character), which translates to 5 MI's. This information also appears on the format selection in the RTC to ASCII function block. So, in your application the date should be stored in MI150-154, and the time should be stored in MI155-159 (or anywhere you like). Quote Link to comment Share on other sites More sharing options...

Davenj Posted February 12, 2015 Report Share Posted February 12, 2015 Do you use MI150 "set feature for a group of operands" for the 5 MI's for the date. Then again for time. Dave Quote Link to comment Share on other sites More sharing options...
