Ethernet IP Station¶

BrowseName: EthernetIPDriverStation
SuperType: Communication station (CommunicationStation)

Object that represents a PLC that communicates via the Ethernet IP protocol.

Properties¶

Name	BrowseName	DataType	Description
Maximum job size in bytes	MaximumJobSizeInBytes	UInt32	Maximum size in bytes of a transmission of tags from the PLC. 0 = 504 bytes (maximum value).
IP Address/Slot (optional)	IPAddress	String	Unique address of the PLC on the network. The slot can be specified for ControlLogix control systems (e.g., 192.168.1.10/1:1).
Port	Port	UInt16	Number of the port used by the TCP-IP connection. It must match the one configured in the PLC.
Timeout	Timeout	Duration	Maximum wait time in milliseconds to receive a response from the PLC.
Physical Address Optimization	PhysicalAddressOptimization	Boolean	Physical Addressing Optimization (used only with Tag Name addressing). If True, the driver gets for each PLC’c tag its physical, i.e. internal, address and use it in read requests, instead of the variable’s name. When many tags with long names must be read, the use of physical addresses can considerably improve the refresh rate of the tags. If this flag is true it requires an initialization phase to translate the variable names into physical addresses, this means that greater is the number of variables on PLC, longer is this initialization phase. Once the physical address initialization is completed the seventh bit of the “State/Command Variable” is set to 1
