Description

The user-defined units are made up of offset (3321h) and scaling value (3322h/ 3323h). If both 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 / 1023 digits
  • Current input (if configurable): x digits * 20 mA / 1023 digits

The following applies for the sub-entries:

  • Subindex 00h: Number of analog inputs
  • Subindex 01h: Analog value 1
  • Subindex 02h: Analog value 2 (if present)
