PCOM

在python中一个非常基本的unitronics pcom协议实现。

如何使用from pcom import commands

from pcom.plc import EthernetPlc

with EthernetPlc(address=('192.168.5.43', 1616)) as plc:

# Read realtime clock

c = commands.ReadRtc()

res = plc.send(c)

print(res)

# Set realtime clock

c = commands.SetRtc(value=datetime.now())

plc.send(c)

# Set MB 300 through 304

values = [True, False, True, True, False]

c = commands.SetBits(code=commands.SetBits.MEMORY, address=300, values=values)

plc.send(c)
