system.device.addDevice

This function is used in Python Scripting.

Description

Adds a new device connection in Ignition. Accepts a dictionary of parameters to configure the connection. Acceptable parameters differ by device type: i.e., a Modbus/TCP connection requires a hostname and port, but a simulator doesn't require any parameters.

When using this function, the arguments MUST be passed in as keyword arguments.

Client Permission Restrictions

Permission Type: Device Management

Client access to this scripting function is blocked to users that do not meet the role/zone requirements for the above permission type. This function is unaffected when run in the Gateway scope.

Syntax - Using deviceType

system.device. addDevice(deviceType, deviceName, deviceProps )

Parameters

String deviceType - The device driver type. Possible values are listed in the Device Types table below.

String deviceName - The name that will be given to the the new device connection.

PyDictionary deviceProps - A dictionary of device connection properties and values. Each deviceType has different properties, but most require at least a hostname. Keys in the dictionary are case-insensitive, spaces are omitted, and the names of the properties that appear when manually creating a device connection.

Returns

nothing

Scope

All

Device Types

Note that this function may be called to add devices using 3rd party drivers: you simply need the driver type, which the module developer will be able to provide.

Driver Name	Device Type
Legacy Allen-Bradley CompactLogix	CompactLogix
Legacy Allen-Bradley ControlLogix	ControlLogix
Simulators Dairy Demo Simulator	DairyDemoSimulator
DNP3 Driver	Dnp3Driver
Allen-Bradley Logix Driver	LogixDriver
Allen-Bradley MicroLogix	MicroLogix
Modbus RTU	ModbusRtuOverTcp
Modbus TCP	ModbusTcp
Omron NJ Driver	com.inductiveautomation.omron.NjDriver
Allen-Bradley PLC5	PLC5

Driver Name	Device Type
Siemens S7-300	S7300
Siemens S7-400	S7400
Siemens S7-1200	S71200
Siemens S7-1500	S71500
Allen-Bradley SLC	SLC
Simulators SLC Simulator	SLCSimulator
Simulators Generic Simulator	Simulator
TCP Driver	TCPDriver
UDP Driver	UDPDriver

Device Properties

The deviceProps parameter is where you supply configuration values to the new connection. Value properties depend on which deviceType was specified. A listing of deviceProps keys can be found on the system.device.addDevice - deviceProps Listing page.

The keys in the deviceProps parameter are case-insensitive. Device properties not specified in the deviceProps parameter will fallback to default values if not specified (where applicable: i.e., "hostname" typically does not have a default value).

Code Examples

Code Snippet

# Below is an example of creating a new Generic Simulator device connection.
# Note that we MUST pass a dictionary as the 3rd parameter, even if it's empty. 

# Call the function
system.device.addDevice(deviceType = "Simulator", deviceName = "New_Generic_Simulator", deviceProps = {} )

Code Snippet

# Add a device using the Allen-Bradley Logix Driver for firmware v21+ devices
deviceProps = {}
deviceProps["Hostname"] = "192.168.1.2"
system.device.addDevice(deviceName="Test1", deviceType="LogixDriver", deviceProps=deviceProps)

Code Snippet

# Below is an example of creating a new S7-1500 device connection.

# Build a Dictionary of parameters
newProps = {
			"HostName" : "10.0.0.1", 
			"Port" : 102 # <---If adding additional parameters, make sure to add a comma.
			}

# Call the function
system.device.addDevice(deviceType = "S71500", \
						deviceName = "My_S7_1500_Device",\
						deviceProps = newProps )
