涉及的从站寄存器：Configured Station Address (0x0010:0x0010)。
使用场景举例：
IgH启动后，通过“配置从站地址”报文将所有从站地址清零，然后通过APWR指令+“配置从站地址”报文，设置各个从站的地址。
一、发送报文
1，IgH dmesg看到的报文
| [18773.710658] EtherCAT DEBUG 0: frame size: 46 [18773.710658] EtherCAT DEBUG 0: Sending frame: [18773.710659] EtherCAT DEBUG: FF FF FF FF FF FF 6C 24 08 29 52 19 88 A4 0E 10 [18773.710663] EtherCAT DEBUG: 08 01 00 00 10 00 02 00 00 00 00 00 00 00 00 00 [18773.710668] EtherCAT DEBUG: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [18773.710672] EtherCAT DEBUG: 00 00 00 00 00 00 00 00 00 00 00 00 |

二、响应报文
1，IgH dmesg看到的报文
| [18773.818568] EtherCAT DEBUG 0: Received frame: [18773.818569] EtherCAT DEBUG: FF FF FF FF FF FF 6E 24 08 29 52 19 88 A4 0E 10 [18773.818575] EtherCAT DEBUG: 08 01 01 00 10 00 02 00 00 00 00 00 01 00 00 00 [18773.818580] EtherCAT DEBUG: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 [18773.818584] EtherCAT DEBUG: 00 00 00 00 00 00 00 00 00 00 00 00 |
2，报文解析
IgH主站广播了设置从站地址的命令，从站0x0001收到后，将本机地址改成了0x0000，以后FPRD/FPWR/FPRW/FRMW需要通过0x0000地址才能访问到该从站。
3，wireshark报文
