python开发SECS客户端

SECS（SEMI Equipment Communications Standard）是半导体设备间通信的标准，Python开发SECS客户端可以使用第三方库如SECS-II（https://github.com/m3team/secs2），PySECS5（https://github.com/jepler/pysecs5）等。

以下是使用SECS-II库开发SECS客户端的示例代码：

from secs2 import Message, Stream, unpack_sid
import socket

HOST = '127.0.0.1' 
PORT = 5555 

# connect to the SECS host
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))

# create a SECS message
msg = Message('S2F13', {'CARRIER_ID': 'ABC123'})

# pack the message into a SECS stream
stream = Stream()
stream.add(msg)

# send the stream to the SECS host
s.sendall(stream.encode())

# receive the response stream from the SECS host
data = s.recv(1024)

# unpack the response stream into SECS messages
stream = Stream()
stream.decode(data)
msgs = stream.messages

# extract the message data from the response
data = {}
for msg in msgs:
    sid, svid = unpack_sid(msg.header)
    if sid == 'S2F14':
        data = msg.body

# print the response data
print(data)

# close the socket connection
s.close()

以上代码示例中，创建了一个SECS-II消息对象并打包为Stream流发送到SECS主机，然后接收SECS主机的响应并解码为SECS-II消息对象，并从中获取回复数据。
