Voltage values from 0…10 VDC
The decimal values for the current values from 0…10 VDC can be calculated by means of the follow-
ing equation:
decimal value = 409.5 1/V ÷ voltage value
The value range:
0 V…10 V
is displayed as follows:
000
hex
…7FFF
hex (decimal:
0…4095)
The decimal value can easily be changed into a hexadecimal value (see s. S. 510).
Voltage values from -10…10 VDC
The decimal values for the current values from -10…10 VDC can be calculated by means of the fol-
lowing equation:
For positive values 0 …10 VDC:
decimal value = 204.7 1/V × voltage value
The value range:
0 V…10 V
is displayed as follows:
000
hex
…7FF
hex
(decimal: 0…2047)
For negative voltage values -10 …0 VDC:
decimal value = 204.8 1/V × voltage value
The value range:
-10 V…-0.0049 V
is displayed as follows:
800
hex
…FFF
hex
(decimal: -2048…-1)
The decimal value can easily be converted into hexadecimal value. The two’s complement for the
12 bit values corresponds to the dual numbers in the positive range.
As the numbers are represented left-justified, a ”0” has to be added to the 3-digit hexadecimal value
or the number has to move one digit to the left s. S. 510.
