ADVANCE PRODUCT INFORMATION - JUL 26, 2011
6.3
IO-Link-Transceiver
The device contains two channels with a high-voltage digital transmitter (output: CQ_OUTx) and
receiver (input: CQ_INx). The transmitter and receiver are accessible by both – a parallel interface
(TXD, TXEN, RXD) and by SPI in IO-Link or SIO mode. The digital pins are supplied by VDD voltage.
The input thresholds and output levels are referenced to this voltage.
It can be used in the following ways:
a) CQ_OUTx is used as standard output (SIO) to drive ohmic loads, inductive loads or bulb lamps
b) CQ_INx is used as standard digital input type 2 according to IEC 61131-2
c) CQ_OUTx and CQ_INx are used together as IO-LINK port for data transfer rates of 4,8 kBaud, 38,4
kBaud or 230,4 kBaud.
6.3.1
IO-Link-Transmitter
The push-pull transmitter is activated with high level on pin TXEN and drives the CQ_OUT pin Low or
High in accordance to the inverted logic level on pin TXD. A slope control limits EMC emission.
