Analog Value Representation For Analog Output Channels - Siemens SIMATIC SM 335 Manual

Data Exchange with the SM 335
3.1.4

Analog value representation for analog output channels

The table contains the analog value representation of the SM 335's output chan-
nels.
12 bits (+VZ) of the output value are converted in the 0-10 Volt range.
Bit 0, Bit 1 and Bit 2 are not converted.
11 bits + VZ of the output value are converted in the + 10 Volt range.
Bit 0, Bit 1, Bit 2 and Bit 3 are not converted.
