我是 Modbus python 的新手，现在我对我的第一步有一些疑问
剧本：
from pymodbus.client.sync import ModbusTcpClient
host = '10.8.3.10'
port = 502
client = ModbusTcpClient(host, port)
client.connect()
#Register address 0x102A (4138dec) with a word count of 1
#Value - MODBUS/TCP Connections
#Access - Read
#Description - Number of TCP connections
request = client.read_holding_registers(0x3E8,10,unit=0)
response = client.execute(request)
print response
#print response.registers
print response.getRegister(12)
print response.registers[8]
client.close()
结果：
============= RESTART: D:\Users\mxbruckn\Desktop\read_modbus.py =============
ReadRegisterResponse (38)
0
0
>>>
现在的问题：
我从寄存器 1000, 10 Words, with slave number 0 中读取。这是正确的，但是值 38 是什么意思 …
