BIS U-602_ Processor Unit
TCP/IP / RS232
10
The processor unit is the link between data carrier and controlling system. It manages two-way
data transfer between data carriers and antennas and provides buffer storage.
The processor unit uses the antennas to write data from the controlling system to the data
carrier or read data from the carrier and make it available to the controlling system.
Controlling systems may be the following:
– A control computer (e.g. industrial PC)
– A PLC
In order to ensure data integrity, the data transfer between the data carrier and processor unit can
be monitored using a CRC-16 data check.
The processor unit and controlling system communicate
– Via the RS232 serial interface (BIS U-6020)
– Via the physical Ethernet network (BIS U-6027)
The device uses the Internet Protocol (IP) for network communication. The Transmission
Control Protocol (TCP) is used to ensure all the data is transferred in the correct sequence
without error.
