from scada_tuna import Tuna
# 用法总结：
tuna = Tuna('modbus://10.8.7.6:502?timeout=5.0&series=H5U').connect()
# tuna = Tuna('mc_3e://172.16.1.153:8100?timeout=5.0&series=L').connect()
print(tuna)
# 单次写入各种类型的数据
tuna.write('R100', 'int', 87)
tuna.write('D100', 'int', 86)
tuna.write('D200', 'long', 50054)
tuna.write('D205', 'float', [23.23, 34.56])
tuna.write('D210', 'string', 'hello world!')
print(tuna.read('R100', 'int'))
print(tuna.read('D100', 'int'))
print(tuna.read('D200', 'long'))
print(tuna.read('D205', 'float', 2))
print(tuna.read('D210', 'string', 12))
# 批量写入多种类型的数据
buffer = Buffer().append(89, 'int').append(12.23, 'float').append("hello world")

print(tuna.read('D504', 'string', 11))
# 批量读取多种类型的数据
buffer = tuna.read('D500', None, 20)
print(buffer.read('D500', datatype='int'))
print(buffer.read('D502', datatype='float'))
