Description
Demonstration circuit 2228A is a complete 8-port IO-Link
Master that uses two
LTC
IO-Link v1.1 physical interface (PHY). DC2228A operates
either with an external supply V
(PoE) system. The IO-Link stack protocol runs on an
NXP microcontroller. A software Control Tool operates
the DC2228A.
