Convert number system

To convert from one number system to another number system (for example
from decimal to hexadecimal), you first require a pocket calculator for
programmers.
If you are using a Windows PC, you can start the calculator under "Start".
1. In the menu, change the calculator to "Programmer".
2. The selected number system is indicated by a blue bar.
– Hexadecimal (HEX)
– Decimal (DEC)
– Octal (OCT)
– Binary (BIN)
3. Enter a value.
4. The value is converted into the other number systems.
For example 13 h (hexadecimal) = 19 d (decimal).

Read out binary code

Using the index, you can identify which bit of the binary code must be
considered.
The index is contained in table 2,  5.5 "Read bit addresses",  22.
Low water switch bit address: 132h
• 13 = word address (hexadecimal number)
• 2 = index
Index 2 means that the bit at numbering position 2 indicates the status of the
parameter.
There are two different statuses:
• 1 = ON
• 0 = OFF
1. Number the binary code from right to left.
2. Begin the numbering at 0:
0 - 1 - 2 - 3.
• Decimal 7 = binary 0
↑
• Parameter index: 3
• Read direction <----------------------------------- (bit numbering from
right to left)
• Bit value 1 is located at numbering 2 position.
Result: The low water switch is ON!
– 0111 = switch on
– 0011 = switch off
