  • Page 4: General Information

    GX Works 2 (PNDP) Technical information 2 General information The function block FB_SICK_RFU6xx_PNDP supports data exchange between a SICK RFU6xx RFID interrogator and a Mitsubishi Q-Series PLC via PROFIBUS or PROFINET. Functionality of the function block: Send a software trigger via the PLC...

  • Page 5: Module Description

    GX Works 2 (PNDP) Technical information 3 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.

    RFU6xx FB for GX Works 2 (PNDP) Technical information 3.3 Timing Figure 4: Timing diagram 1: The selected function (in this case “TriggerOn”) is executed if the “Req” input is triggered by a rising edge. The “TriggerOn” bit must be selected at the same time/in advance. Only one function can be executed at the same time, otherwise an error will terminate the se- quence.

    RFU6xx FB for GX Works 2 (PNDP) Technical information 3.5 Value transfer The “Data” parameter of the function block contains all input and output parameters for the supported block functions. The data structure has a fixed definition and may not be modified. Figure 5: ST_SICK_RFU6xx PLC data type Page 8...

  • Page 9: Mode

    RFU6xx FB for GX Works 2 (PNDP) Technical information 3.5.1 Mode The RFU can only communicate with a single transponder at the same time. For this reason, read and write commands are always addressed. The function block uses the transponder UII (Unique Item Identifier) in order to identify the transponder.

  • Page 11: Single-Tag Mode: Sopas Object Trigger Control

    RFU6xx FB for GX Works 2 (PNDP) Technical information 3.5.2 Single-Tag mode: SOPAS object trigger control The object trigger control settings define the status of reading gate (open / closed). The de- vice sends a reading result to the PLC after each reading gate. The function block uses this mechanism in order to read the UII, the PC-Word and RSSI values of the corresponding transponder.
  • Page 12 RFU6xx FB for GX Works 2 (PNDP) Technical information Please ensure that the format of the blocks "RSAVG1...4" are set to hexadecimal format (double-click the respective block). The "PCUII" block may not be changed. Figure 8: Settings for RSSI blocks (RSAVG1...4) Depending on the number of tags located in the receiving range of the RFU and the config- ured RSSI threshold, the following ASCII telegrams are sent by the device: Case 1: (Only one tag in the field):...
