Function

The BIC system consists of the stationary Base
component and the mobile Remote component. With the
BIC system, unidirectional electrical power is transmitted
from the Base component via an air gap to the Remote
component. The transmission of data is bidirectional. The
transmission distance between Base and Remote can be
up to 5 mm depending on the power taken.
For further information, see document IO-Link
configuration under www.balluff.com on the
product page.
IO-Link master
Fig. 4-2: Function illustration using the example of IO-Link mode
Transparent channel: In IO-Link mode, the BIC system
transfers the IO-Link port data from the IO-Link master
(see Fig. 4-2) to the Remote BIC system component. In
this way, the functionality of the IO-Link master port is
made available transparently on the Remote component
without contact.
In addition to the transparent channel mentioned above,
the BIC system has a second IO-Link communication
channel: the diagnostic channel. This can be accessed via
pin 2 of the Base component and functions in parallel and
independently of the transparent channel. During
operation, diagnostic information on this channel can be
read out by the BIC system itself (see Fig. 4-3).

Using the diagnostic channel is optional. If the diagnostic
data do not have to be evaluated, this connection can be
left unused. Without IO-Link communication, pin 2
functions as a transparent, bidirectional digital IO channel
between Base and Remote.

REMOTE
IO-Link SIO mode on the transparent channel is not
supported, although the Remote component is able to
wake up a sensor that is in SIO mode. Pin 2 is available for
the transmission of digital IO signals, the diagnostic
channel cannot be used in this case.
The maximum output current at pin 2 of the
Remote component is 50 mA and is only intended
for the transmission of digital signals. On the
Remote side, the supply of other devices is not
usable.
This device supports condition monitoring
functions. For details, see document IO-Link
configuration under www.balluff.com on the
product page.

Pin 2 function
Pin 2 on the base component transmits the high-active
signal state from the IO-Link port of the master to the
remote component or to the IO-Link device. When
planning the system, it must be taken into account that the
voltages at pin 1 and pin 2 on the remote side have a
common source. This means that the current taken from
pin 2 reduces the available current at pin 1.
Another important point is that the supply voltage of the
base component is the origin of the remote voltage
(voltage at pin 1). This is normally the supply voltage of the
sensors in the system.
On the remote side, the voltage at pin 2 must not be
confused with the actuator voltage of the system. This
voltage is actually the voltage of the sensor system,
because on the remote side both pins have the same
voltage source.
Fig. 4-4: Pin 2 function
The use of pin 2 as a current source for actuators is
therefore not appropriate. If a separate voltage for the
actuators is required on the remote side, then a second
BIC system must be installed (see Inductive couplers for
power supply at www.balluff.com).
Pin 2 of the BIC system is only used for bidirectional signal
transmission between base and remote. If the diagnostic
channel is active on the base side, then the input or output
(pin 2) of the remote side can be controlled via the process
data.
