Processing: local, no forwarding
Within a PLC program (ST), data can be read from the object directory of an EtherCAT slave via the function block FB_EcCoeSdoRead and SDO (service data object) access. Use the parameters nSubIndex and nIndex to selected the object to be read. This block is part of the (standard) library Tc2_EtherCAT (see TwinCAT 3 Engineering → PLC → Libraries → TwinCAT 3 PLC Lib: Tc2_EtherCAT → CoE under http://infosys.beckhoff.com).
