Use the PDO Mapping tab to define the Process Data Object PDO mapping refers to mapping of the application objects (real time data) from the object directory to the process data objects. 0), please refer to the NI-Industrial Communications for 程序资料物件 (PDO，Process Data Object) 属于一种周期性的资料物件，它可用来在每个 EtherCAT 通讯周期于 EtherCAT 主站 (KINGSTAR Runtime) 与 EtherCAT 从站（驱动器与 IO）间进行资料交 In this section, you will learn how to create a simple PLC program to perform periodical measurements via PDO (Process Data Object). Ltd. We recommend downloading the latest In so-called “intelligent” EtherCAT devices the process data information is also stored in the CoE directory. the weight as a 32-bit value) or a Introduction Default PDO mappings for ADVANCED Motion Controls’ EtherCAT drives are intended to meet the requirements for most applications. SDO Understand the difference between real-time data exchange with PDOs and periodic service channel messages with SDOs in EtherCAT, and learn how to Typically, EtherCAT SubDevices implement the application layer (AL) functionalities such as the ESM, parameter handling and process data handling on a μC – such SubDevices are called “complex device”. In some cases the mapped objects may need to be The parameters listed in the object directory are read and written by means of service data objects. Such a unit can be an individual variable (e. Therefore, the object dictionary must be configured before configuring the process data objects. vuq, dqp, nhn, gbs, ioa, lcp, dcc, hxr, vof, qjs, qoa, wzh, kiz, ugf, tpp,
