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
-
Receive telegrams sent by the device which can be configured in the SOPAS
i
output
format (reading results)
-
Read and write transponder content (Single-Tag / Multi-Tag mode)
2.1 Supported PLC controls
This function block can be used in combination with iQ-Series PLC which is able to connect a
PROFIBUS or PROFINET device directly or via a gateway module (e.g. QJ71PB92D).
2.2 PROFINET / PROFIBUS configuration
Before starting with the function block, it is necessary to setup the hardware in the I/O con-
figuration. The function block communicates with connected device via process data varia-
bles. These variables contain the cyclic process data of the fieldbus device. The length of the
selected containers indicates the amount of data, which can be exchanged in one fieldbus
cycle.
Please note!
The FB is only compatible with the following process data containers:
-
32 byte input
-
32 byte output
Other modules can be plugged (e.g. parameter modules or Control In/Out
modules) and have no influence on the functionality of the FB.
If a telegram is longer than the projected module, the data will be transmitted fragmented
over several PLC cycles. The data flow is managed via a handshake mechanism by the func-
tion block.
