ReadEIPBuffer

Reads (consumes) data sent by a remote client using EtherNet/IPprotocol.EtherNet/IP is an application-level protocol implemented on top of Ethernet and TCP/IP protocols, allowing the transfer of data in industrial environments over the Ethernet. For more information on the EtherNet/IP protocol, go to odva.org.

The referenced Buffer data structure, which is created by a FormatInputBuffer function, defines how the received data is interpreted. For more information, see FormatInputBuffer.

Note:

For In-Sight vision systems running In-Sight 5.1.0 and later firmware, when a job containing this function is loaded, it will automatically be replaced by the ReadUserDataBuffer function (the Protocol parameter will be set to Default). For more information, see ReadUserDataBuffer.
This function is only available on In-Sight vision systems running In-Sight firmware 4.x.x, and is not available on In-Sight vision systems running In-Sight firmware 5.1.0 and later. For a complete list of models and supported firmware versions, see Firmware Versions.
Although an In-Sight vision system can communicate with more than one device at the same time using EtherNet/IP protocol, it is not recommended to have more than one connection at a time.
In-Sight vision systems support both Explicit and Implicit EtherNet/IP messaging. For more information, see In-Sight Assembly Data Configuration (Implicit Messaging).See Example.
ReadEIP($A$0,"0d:4d:8s") in cell A4, reads 2 32 bit integers and a null terminated string from the PLC.
GetBufferData($A$4,0) displays the first 32 bit integer.
GetBufferData($A$4,1) displays the second 32 bit integer.
GetBufferData($A$4, 2) displays the string.

ReadEIPBufferInputs

Syntax: ReadEIPBuffer(Event,Buffer)

Parameter	Description
Event	Specifies the update event on which to read data. This parameter must be a reference to one of the following: The Image data structure in cell A0, containing the AcquireImage function. For more information, see AcquireImage. A cell containing an Event function. For more information, see Event. A cell containing a Button function. For more information, see Button.
Buffer	Specifies a reference to a Buffer data structure created by a FormatInputBuffer function, which defines how the received data is interpreted. Note: The maximum length for input data is 4,000 bytes. Formore information, see In-Sight Assembly Data Configuration (Implicit Messaging).

Parameter

Description

Event

Specifies the update event on which to read data. This parameter must be a reference to one of the following:

The Image data structure in cell A0, containing the AcquireImage function. For more information, see AcquireImage.
A cell containing an Event function. For more information, see Event.
A cell containing a Button function. For more information, see Button.

Buffer

Specifies a reference to a Buffer data structure created by a FormatInputBuffer function, which defines how the received data is interpreted.

Note: The maximum length for input data is 4,000 bytes. Formore information, see In-Sight Assembly Data Configuration (Implicit Messaging).

ReadEIPBufferOutputs

Parameter	Description
Returns	A ReadEIP data structure containing the data sent by a client or #ERR if any input parameters are invalid or a connection from a client has not been established.
Results	Data in the ReadEIP structure is accessed using the GetBufferData function. For more information, see Input/Output.
