以下是一个使用 Python Snap7 库检测连接状态的示例程序:
```python
import snap7
def check_connection(ip_address):
client = snap7.client.Client()
client.set_connection_type(snap7.types.ConnectionType.PG)
client.set_param(snap7.types.PGParam.PG_RECV_TIMEOUT, 5000)
client.set_param(snap7.types.PGParam.PG_SEND_TIMEOUT, 5000)
client.set_param(snap7.types.PGParam.PG_CONNTYPE, snap7.types.PGConntype.PG)
client.set_param(snap7.types.PGParam.PG_PORT, 102)
client.set_param(snap7.types.PGParam.PG_LOCAL_TSAP, 1)
client.set_param(snap7.types.PGParam.PG_REMOTE_TSAP, 1)
client.set_param(snap7.types.PGParam.PG_REMOTE_ADDR, ip_address)
try:
client.connect()
return True
except:
return False
finally:
client.disconnect()
```
你可以将要检测的 PLC 的 IP 地址作为参数传递给 `check_connection` 函数,如果连接成功,函数将返回 `True`,否则返回 `False`。
