IO-Link
communication
The BIC system transmits the IO-Link protocol across the air gap to the base and remote
units and transmits all IO-Link input and output data, regardless of the length of the process
data. The IO-Link protocol is transmitted without any restrictions so the BIC system
parameters do not need adjusting. The device connected to the BIC system has to be
integrated in the control.
An IODD is therefore not required for the bidirectional BIC Q40.
Note
The BIC system can only be operated using Balluff IO-Link masters. Using IO-Link
masters produced by other manufacturers can lead to disruptions in
communication.
Transparent PIN2
Pin 2 on base and remote is transparent and transmits the signal status
"High Active" from the IO-Link port on the master to the IO-Link device.
5.2. Connection time
The time needed to establish the connection of base and remote is affected by many
different variables. Start-up speed and angle play just as much of a role as the IO-Link
device connected to the remote and the IO-Link parameters set within it. The type of IO-
Link master used and its parameter settings also affect the connection time. These
variables are all application-specific and therefore cannot be generalized.
The measurements carried out by Balluff to determine the connection time were done using
a Balluff EtherNet-IP master in combination with the Balluff IO-Link device
“BNI IOL-302-00-Z012”. The distance from base to remote was 5 mm without axis and
angular offset. In total, 100,000 connection cycles comprising a variety of directions and
speeds were evaluated.
The power reduction function (see Section 4.2) substantially influences the connection time
to an extent that depends on the particular system. Therefore, a separate connection time
is specified for every base variant:
Base variant (Order-Code)
Typical connection time in seconds
BIC0070
0,9
BIC0072
1,2
Note
The typical connection times specified here correspond to the arithmetic mean of
100,000 connection times.
