Module description
The FB_SICK_RFU6xx_PNDP function block simplifies the usage of a SICK RFU6xx RFID
interrogator on Mitsubishi iQ-Series PLCs.
The function block is working asynchronously, which means the processing is done via vari-
ous function block call ups. Therefore it is necessary that the function block is called cyclical-
ly in the user program.
The RFU library can only be used in combination with the SICK_AutoIdentBase_PNDP li-
brary. This library contains the FB_SICK_CCOM_PNDP, which facilitates the communication
between the PLC and the device. The F_SICK_GetValue/F_SICK_SetValue functions are
used internally to serialize and de-serialize device telegrams.
