Process Purpose
The RFID Read process is used in a “single tag” operation (synchronous operation) to read a tag's memory bank and store that information into variables.
When reading more than 64 bytes of the User Memory Bank (for instance, the complete memory bank), the system will read the data in blocks of 64 bytes (RFID reader will flash multiple times).
Make sure you have already created the required RFID profile(s). See Creating an RFID Profile.
Check the necessary steps to create an RFID program in To Create an RFID Program.
The RFID Read process MUST NOT be associated to an On RFID Tag Read event.
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 RFID Read process.
If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.
