4.4 Effect on analog value representation
4.4.1 Effect of the supply voltage and the operating state on analog input values
The input 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). The
table below shows this dependency..
