Memory Requirement of the Numerical Converter
The numerical converter function block requires 32 bytes of memory plus 4
bytes per constant on the function block input.
Function of the Numerical Converter Function Block
BCD Mode
The BCD value at
>I1
is provided in decimal format at the input. The binary
value is formed from this. The binary value is interpreted as a BCD value.
Values greater than 9 (1001) are set to the value 9. The BCD value is output as
a decimal value at the output QV>.
Example 1:
Input value >I1: +9
dec
Binary value: 1001
Decimal value QV>: + 9
Example 2:
Input value>I1: +14
dec
Binary value: 1110
Decimal value QV>: + 9
IMPORTANT
The numerical converter function block must be enabled so
that it can work. Coil NC..EN is active. If coil NC..EN is
not active, the entire function block is deactivated and reset.
The output value is set to zero.
