Effect on analog value representation 

4.4.1

 

Effect of the supply voltage and the operating state on analog output values 

The output values of the analog modules are dependent on the supply voltage for 

electronics/encoders and on the operating state of the PLC (CPU of the DP master). This is 

illustrated by the table below.  
 

Table 4-5 

Relationship between the analog output values for the operating state of the PLC (CPU 

of the DP master) and the supply voltage L+.
