4.6.2
Convert UINT or INT to BCD4
The function passes power flow when power is received, unless the conversion would result in a
value that is outside the range 0 to 9,999.
Tip:
Data can be converted to BCD format to drive BCD-encoded LED displays or presets to
external devices such as high-speed counters.

Parameter Description
IN
The UINT or INT value to convert to
BCD4.
Q
The BCD4 equivalent value of the original
UINT or INT value in IN.
Example - UINT to BDC4
Whenever input %I00002 is set and no errors exist, the
UINT at input location %I00017 through %I00032 is
converted to four BCD digits and the result is stored in
memory locations %Q00033 through %Q00048. Coil
%M01432 is used to check for successful conversion.
Example - INT to BCD4
Whenever input %I0002 is set and no errors exist, the INT
values at input locations %I0017 through %I0032 are
converted to four BCD digits, and the result is stored in
memory locations %Q0033 through %Q0048. Coil %Q1432
is used to check for successful conversion.
GFK-2950C
When this function receives power flow, it converts the input unsigned
(UINT) or signed single-precision integer (INT) data into the equivalent
4-digit Binary-Coded-Decimal (BCD) values, which it outputs to Q.
This function does not change the original input data. The output data can
be used directly as input for another program function.
