Good day if anyone can help

I am trying to display my data in hex values, but only find that decimal works in ccw12. is there any way to display those decimal numbers in hex?

what version are you running?


can you upgrade assuming you are at a lower version ?

Yes.

Is this a homework assignment?

What kind of data (UINT/INT, UDING/DINT, REAL, etc.)?

Btw, they are binary numbers, not decimal numbers; but yes, CCW probably always displays their values using decimal digits.

Note: this would be much cleaner in ST.



Here is the main program running.

• Variable "the_dint" is a DINT with a value of -2.
• Variable "the_hex" is an 8-character string.
• User function i2hex takes a DINT as input and returns an 8-character string as output.

Here are the first few rungs of the i2hex user function. The last rung is duplicated five more times with the REPLACE instruction Pos parameter being reduced by one per rung ...



Here are the last two rungs of user function i2hex. the final nibble is converted to a hexadecimal character and inserted into variable "lcl_str," then "lcl_str" is copied to be the output of user function i2hex.



Here are the variables for user function i2hex. The key is the 16-element array of 1-character strings s15s; one low nibble at a time is extracted from the local DINT copy of the input DINT, and the resulting nibble is subtracted from the local DINT and the rest of the local DINT is shifted down by four bits. The nibble's value in the range [0..15] is used to select a one-character element of s15s and REPLACE one character in the lcl_str output string. Finally, lcl_str is copied to be the output of user function i2hex.
