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
Aux Name	Select the auxiliary device profile that will receive data from the drop-down list. If required, click to access an Aux profile list and create/edit an Aux profile. See Aux.
Flush Buffer After “Receive Data”	Check this option to empty the buffer before receiving the file.
Start Character
Select the “Start Character” that identifies the beginning of received data. Either check “None”, “STX” or “Other” (in this case, enter the intended character in the box that activates when "Other" is checked). See Abbreviations.
Stop Character
Select the “Stop Character” that identifies the end of received data. Either check “ETX", “CR”, “Other” (enter the intended character in the box that activates when "Other" is checked) or "Length (insert a number in the newly activated box). See Abbreviations.
Store Result into Variable
