AKT2G-AN-240 CoE Object Description


  • Relevant Objects

    The object description refers to the analog input terminals for Pt100 (RTD) in 1 to 8 channel versions. Observe the indices with regard to the objects relevant for the respective terminal (channel dependent).

Introduction

The CoE overview contains objects for different intended applications:

  • Objects required for parameterization and profile-specific objects required during commissioning
  • Objects for indicating internal settings (may be fixed)

The following section first describes the objects required for normal operation, followed by a complete overview of missing objects.

  • The filter properties are set only via index 0x8000:15

    The filter frequencies are set for all channels of the AN-240 terminals centrally via index 0x8000:15 (channel 1).

    The corresponding indices 8010:15 of the AN-240 have no parameterization function!

Profile-specific objects (0x6000-0xFFFF)

The profile-specific objects have the same meaning for all EtherCATClosedEtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs slaves that support the profile 5001.
