Conversion Binary To Ascii/Hexadecimal; Conversion Ascii/Hexadecimal To Binary - HEIDENHAIN TNC 415 Technical Manual

4.4.4 Conversion Binary to ASCII/Hexadecimal (Module 9053)
Converts a block of binary values from the word marker range into a string of ASCII coded
hexadecimal numbers.
The specified number of bytes is read from the place specified by the source address and converted
to a hexadecimal-coded ASCII string. Each byte in the source block makes 2 characters in the
destination string. the destination string is identified by the destination string number.
Possible errors:
- The address for the source block is outside the range 0 to 1023.
- The number of the destination string is outside the valid range (0..3).
Call:
PS K/B/W/D <Source address in Word-RAM>
PS K/B/W/D <Number of destination string>
PS K/B/W/D <Number of data bytes>

Example:
S0 = Hex 63 6
B0 = 99 0110 0011

4.4.5 Conversion ASCII/Hexadecimal to Binary (Module 9054)
Converts a string of ASCII coded hexadecimal values to a block of binary values in the word marker
range.
The string in the string buffer with the specified number is interpreted as a chain of ASCII coded
hexadecimal numbers and converted into a block of corresponding binary bytes. Two ASCII
characters make one binary byte. The binary block is stored in the word marker range starting from
the specified destination address.
Possible errors:
- The number of the source string is outside the permitted range (0..3).
- The address for the destination block is outside the range 0 to 1023.
- The source string contains characters that cannot be interpreted as hexadecimal values (different
characters 0..9, A..F).
- The source string contains an uneven number of characters (the last byte is not fully defined).
- The destination block has no room at the specified address.
