Description

The user-defined units are made up of offset (3321h) and pre-scaling value (3322h). If both object entries are still set to the default values, the value in 3320h is specified in the "ADC digits" unit.

Formula for converting from digits to the respective unit:

  • Voltage input: (x digits – 512 digits) * 20 V / 1024 digits
  • Current input: x digits * 20 mA / 1024 digits

The following applies for the sub-entries:

  • Subindex 00h: Number of analog inputs
  • Subindex 01h: Analog value 1
  • Subindex 02h: Analog value 2
