Process Purpose

The Receive Data process is used to define the structure of the data (type and receiving variables) to be received through a port, from an auxiliary device.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Receive Data process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

Proceed as follows:

Aux Port
Aux Name	Select the auxiliary device profile that will receive data from the drop-down list. If required, click to add another Aux profile or select the one you want to edit. See To Create an AUX Profile and/or To Edit an AUX Profile.
Read Data from/to
Start of Data	Maintain "None" or select the character that identifies the beginning of the received data. See Abbreviations. If you select "Custom", you must define the custom character in the related box which is now active. Enter the intended character or click to select the variable with that value.
End of Data	Select the character that identifies the end of the received data. See Abbreviations. If you select "Custom", you must define the custom character in the related box which is now active. Enter the intended character or click to select the variable with that value. If you select "Length", define the intended length in the "Max Length" option.
Flush Buffer After “Receive Data”	Check this option to empty the buffer after the received data package is stored in a variable.
