2 Meaning of the I/O terminology of a PCD2/3.W525 module
When configuring a W525 module using the Device Configurator or the Profi-S-I/O (or Profibus DP) Network Configurator, the PCD2/3.W525 needs two registers for the analogue outputs and 8 registers for the analogue inputs. Themeaningoftheregistersisasfollows:
