We schould sort 10 values from high to low in a data block. We can already find the biggest number but we've really tried hard and couldn't find any solution. Thanks! Robin

Robin A solution can be found here: Sample program for sorting a data block But for your case, develop your own idea, implement it and share it here for help to rectify your own programming error.

This Sample works as It should, a loop in each 2 adjacent cells are compared and a position change happens when Cell[i]>Cell[i+1]. Attachment SORT.JPG (917 Downloads)

RobinTMK Posts: 6 Rating: (0)	I tried and failed again. The program works just till I want to use the sorting program (FC1). The main program is used as a trigger. You can set a value with IB124. Whenever PIW752 reaches a higher level then the setvalue (IB124), this number wil be written in DB1. This happens every 2 seconds. I hope its clear for you what we're trying to do here. Then we copy the numbers from DB1 to DB2. (with I126.0, the main program stops till I126.0 = 0) The SF occurs when i click I126.1. You'll see in OB1 that I enable the sorting program with I126.1. So it is defenitly the sorting program that causes the problem. I think I just did something wrong with the variables? Because I use bytes in the DB's and in the program it's set as WORD. I really hope I explained it good enough for you. Thank you!

Hello again, I have not checked the whole program , but the main cause of CPU entering the STOP mode comes from the fact that Fc works on WORD and the length of data in DB i snot sufficient for that work.Try again with the following changes in FC1; '//Data Block will be sorted in ascending order. [code] OPN #Data_DB //Open Data Block M002: LAR1 P#DBX 0.0 SET //LET #Sort_done = TRUE S #Sort_done L #DB_length L 1 -I Loop: T #Count //FOR INDEX = Count TO DB_length L B [AR1,P#0.0] //IF M(INDEX) > M(INDEX+1) THEN L B [AR1,P#1.0] <=I JC M003 // change M(INDEX+1) for M(INDEX) L B [AR1,P#0.0] //LET TEMP = M(INDEX) T #Temp L B [AR1,P#1.0] //LET M(INDEX) = M(INDEX+1) T B [AR1,P#0.0] L #Temp //LET M(INDEX+1) = TEMP T B [AR1,P#1.0] SET R #Sort_done //LET #Sort_done = FALSE M003: TAR1 L 8 //NEXT INDEX +D LAR1 L #Count LOOP Loop //End of sorting pass AN #Sort_done //If sorting is not done JC M002 //Jump Conditionally to M002 BE [/code]
