MLSmpConECAT
MLSmpConECATConnects a sampler block to the specified CoE object. The CoE object must be included in a PDO for the specified EtherCATEtherCAT 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 device.
Using this function, you can use any EtherCAT data source as input for the specified sampler block.
