@FieldOrder({"hasDc","phyType","linkCount","activePorts","consumedPorts","_padTopo","parent","parentPort","entryPort"}) public static class Structures.SlaveTopology extends com.sun.jna.Structure
Slave 拓扑子结构 - 对应 C 端 slave_topology_t 原平面字段 hasdc / ptype / topology / activeports / consumedports / parent / parentport / entryport 收敛为 sub-struct. 嵌入到 EcSlave 中段 (Mbx 之后, EepromConfig 之前), 自然对齐. 64 位下: 5×byte (5) + 1 字节填充 + short (2) + 2×byte (2) = 10 字节.
