ReadProfinetBuffer

Reads (consumes) data sent by a remote client using PROFINET protocol. 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.

ReadProfinetBuffer Inputs

Syntax: ReadProfinetBuffer(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.

ReadProfinetBuffer Outputs

Returns

A ReadPNIO 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 ReadPNIO structure is accessed using the GetBufferData function. For more information, see Input/Output.
