Needed to change it to:
```
import asyncio
from plc4py.PlcDriverManager import PlcDriverManager
connection_string = "modbus://127.0.0.1:5020"
driver_manager = PlcDriverManager()
try:
async def communicate_with_plc():
async with driver_manager.connection(connection_string) as connection:
with connection.read_request_builder() as builder:
builder.add_item("Random Tag", "4x00001[11]")
request = builder.build()
future = connection.execute(request)
response = await future
# Access and process data from the response here
data_value = response.response_code # Assuming "Random Tag" is a key
print("Data:", data_value)
except Exception as e:
print("Error communicating with PLC:", e)
asyncio.run(communicate_with_plc())
```
