3.5.6.3 FB_DINTToPBox
This function module converts a DINT value into an ASCII string and copies it into the ParameterBox. The
output can be in decimal, binary or hexadecimal format. Selection is carried out via MODE. Via ROW and
COLUMN the starting position of the string is set in the P-Box display. The parameter LENGTH
communicates the length of the string in characters. In decimal MODE the parameter POINT inserts a
decimal point into the number to be displayed. POINT specifies how many characters are to the right of the
decimal point. The function POINT is switched off with the setting 0.
If the number contains more characters than the length allows and no decimal point is set, the overflow is
indicated by the character "#". If there is a decimal point in the number, all numbers behind the decimal point
by be omitted if required. In hexadecimal and binary MODE the lowest value bits are displayed if the set
length is too short.
As long as ENABLE is set to 1, all changes at the inputs are adopted immediately.
If DONE switches to 1, the string has been transferred correctly.
In case of error, ERROR is set to 1. In this case, DONE is 0. The corresponding error code in the ERRORID
applies.
DONE, ERROR and ERRORID are reset with a negative flank on ENABLE.
Examples:
Setting Number to be displayed P-Box display
Length = 5
12345 12345
Point = 0
Length = 5
-12345 ##### Point = 0
Length = 10
123456789 123456,789 Point = 3
Length = 8
123456789 123456,7 Point = 3
