station = connection.add_station(common_address=1) # Add a point for a Single Command (IOA 100) command_point = station.add_point(ioa=100, type=c104.Type.C_SC_NA_1) Use code with caution. Step 3: The Write Command
Always log the User ID and Timestamp for every write command. In industrial settings, knowing who turned off a generator at 2:00 AM is critical. Summary Table: Common Write Commands Switching C_SC_NA_1 (45) Turning a light or motor on/off. Valve Control C_DC_NA_1 (46) Opening/Closing a water or gas valve. Setpoint C_SE_NC_1 (50) Setting a target temperature (float). Station — iec104-python 2.2 documentation
V104 allows for multiple connections. If your primary station goes down, ensure your write scripts can failover to a secondary IP. write at command station v104
Every write operation includes a COT. Look for ACTIVATION_CONFiRM to ensure your command was accepted.
Depending on your security and safety protocols, you will either use or Select-Execute . Direct Execute: Sends the command immediately. station = connection
import c104 # Connect to the remote station at its IP address connection = c104.Connection(ip="192.168.1.50", port=2404) connection.start() Use code with caution. Step 2: Define the Station and Point
While "Command Station V104" might sound like a sci-fi cockpit or a high-end gaming desk, in the world of industrial automation and smart infrastructure, it refers to a specific protocol environment. Specifically, it relates to the protocol, often managed via Python libraries like iec104-python . Station — iec104-python 2
When you write at a V104 station, you must choose the correct type: Single Command (SC): On/Off switches (Type ID 45).
