Read bit addresses

Based on the bit addresses, you can read off the respective parameters.
Example: Check whether the low water switch is on or off.
1. In table 2, the low water switch 132h is listed under "Digital inputs".
• Word address #19d or #13h (d = decimal; h = hexadecimal)
• Index: 2
Table 2: The following data can be requested:
Designation
System pressure in 1/100 bar (not with Servitec
Levelcontrol)
Fill level in % (not with Servitec / here optional filling
pipe pressure in 1/100 bar)
Digital outputs
Digital inputs

Note!
Only decimal numbers can be entered in the ComTest Pro software. Hexadecimal numbers (h) must be converted to decimal numbers
"Convert number system", 
2. Open the ComTest Pro software and change the register in step 2 to 19 (= 19d, as the low water switch is stored under the word address 19d). Set the number of
registers to "1" (#Register), because only one parameter is to be read off.
3. Press the "Start" button.
You will see a yellow-highlighted decimal number in the register history: 7d
