程序包 com.darra.ethercat.data

类 Structures.SlaveMetadata

java.lang.Object
com.sun.jna.Structure
com.darra.ethercat.data.Structures.SlaveMetadata
封闭类:
Structures
@FieldOrder({"identity","groupName","deviceName","smCount"}) public static class Structures.SlaveMetadata extends com.sun.jna.Structure
Slave Metadata 子结构 - 对应 C 端 slave_metadata_t identity (slave_identity_t) + group_name + device_name + sm_count 收敛为 sub-struct. 嵌入到 EcSlave 中段 (mbxstatus 之后), 自然对齐. 64 位下: 20 (identity) + 41 + 41 + 2 + 隐式填充 ≈ 104 字节 (uint32 对齐).
