At the same time the data splitter (4) provides again all initial SIO signals of the
sensor (1) to the controller / installation (2) so that the actual control task remains
unchanged�
The SIO signals are generated even without connected IO-Link master (5) or
active communication with the master so that the initial control task is carried out
at any time�
It is now possible to read process and diagnostic data or to configure the sensor
via the IO-Link master irrespective of the control task�
4.2 Write protection against unauthorised access
When the device is delivered the IO-Link master ((5) in fig. 4.2) only allows read
access to the connected IO-Link device (1). Write access is not possible until the
write protection has been removed�
To remove write protection:
► Connect and configure the device according to fig� 8�1 (→ 8)�
4.3 IO-Link
This device has an IO-Link communication interface which requires an IO-Link
capable module (IO-Link master) for operation.
The IO-Link interface allows direct access to process and diagnostic data (→ 4.1)�
Furthermore, communication with a USB IO-Link master is possible via a
point-to-point connection (→ 8)�
The IODDs necessary for the configuration of the data splitter and the connected
IO-Link device, detailed information about process data structure, diagnostic
information, parameter addresses and the necessary information about the
required hardware and software can be found at www�ifm�com�
5 Installation
5.1 Installation location / installation environment
► Install the unit at a suitable location�
- Observe the protection rating�
- Avoid heat build-up or impermissible heating of the device�
- Observe the maximum ambient temperature (→ Technical data).
