Dialog: New Connection, Add Connection

Object: EtherNet/IP Adapter

Object: EtherNet/IP Scanner

Generic connection (freely configurable)

The dialog contains the parameters for the new connection.

Table 12. Connection Path Settings

Automatically generated path

The Connection Path is generated automatically from the values for Configuration assembly, Consuming assembly, and Producing assembly.

User-defined path

The Connection Path is specified manually in the corresponding input field.

Path defined by symbolic name

The path is specified by a symbolic name.

Requirement: The device must support symbolic connection paths.

Table 13. General Parameters

Connection Path	The connection path is used to address one or more objects in the adapter which provide the input data and receive the output and configuration data. Requirement: The connection path is set to User-defined path.
Symbolic name	An ANSI string is used instead of the normal connection path. See the manual of the respective EtherNet/IP Adapter for permitted ANSI strings. Requirement: The connection path is set to Path defined by symbolic name.
Trigger type	Cyclic: Data exchange takes place cyclically at intervals set by the RPI. Change of State: Data is exchanged automatically after a change to the scanner outputs or adapter inputs. Application: Not implemented
Transport Type	Details for this can be taken from the specifications CIP Volume 1 and Volume 2.
RPI (ms)	Requested Packet Interval Length of the time interval (in milliseconds) in which the transmitting application requests the transmission of data to the target application. This value must be a multiple of the bus cycle task.
Timeout multiplier	In case of device failure, there is a time delay (RPI * Timeout multiplier) before the device state switches to "Error".

Use this option to employ existing connections from an EDS file. The data which can be changed is defined in the EDS file.

Table 14. Scanner to Adapter (output), Scanner to Target (output)

O -–> T Size (Bytes)	Amount of data from scanner to adapter
Proxy config size (bytes)	Size of the proxy configuration data
Adapter config size (bytes)	Size of the adapter configuration data
Connection type	Null: A network connection is not established. Multicast: A network connection is established. The connection data can be received by multiple consumers. Point to Point: A network connection is established. The connection data can be received by exactly one consumer.
Connection priority	Two scanners using different priorities to one adapter can cause conflicts. Adapting the connection priority solves this problem.
Fixed/Variable	See the specifications CIP Volume 1 and Volume 2 for details of the parameters.
Transfer format
Inhibit time
Heartbeat multiplier	Requirement: The Transfer format is Heartbeat. Extends the interval at which the scanner sends heartbeat messages to the adapter. This value is multiplied by the RPI value. Example: RPI = 10ms and Heartbeat multiplier = 10 causes a message to be sent every 100ms.
