Balluff’s IO-link based RFID system simplifies network topology and PLC setup by using the IO-link block to treat the RFID data like standard I/O points, and reduces costs by running multiple RFID readers off 1 I/O block using standard, 3-conductor sensor cables.
The IO-link protocol allows connection of a complex device such as an
RFID processor to an industrial network via a gateway using standard
discrete sensor wiring. The solution utilizes cost-equivalent
IO-link-based RFID heads and processors to provide data reliability.
The solution can replace the I/O enclosure, 4 shielded cordsets, and a
4-port RS232 PLC module with a single IO-Link Expansion Module and 4
3-conductor, non-shielded cordsets.
