With a fixed resolution of 1mm and an available process data width of 14bits, a maximum distance measurement value of 16,383mm
can be displayed. Higher values are output as 16,383mm.
7.4.2 Safety-related use of the IO-Link interface
Safety-related distance values can be transmitted as 14-bit measured values via the
IO-Link interface (process data formats0 and 4). The status of safety-related switching
functions can also be transmitted via the process data (process data format0). The
possibility of transmitting safety-related data with PLb via IO-Link is determined as part
of the safety verification of the DT35S.
7.4.2.1 System integration
The system integrator is responsible for ensuring that the sensor is correctly connected
to the logic unit or controller. It is especially important in this regard to ensure that
the logic unit evaluates the sensor (with the associated configuration) at the correct
port or channel interface. It must also be taken into consideration that the sensor
and the evaluating logic unit or controller must constitute a point-to-point connection
(no intermediate gateways allowed). The system integrator must always provide specific
proof of safety for the respective application or for the overall system (including the
communication network used). This must also specifically include a safety-related eval‐
uation of the logic unit or controller used.
7.4.2.2 Parameterization of the device
Parameterization of the device via an IO-Link data interface integrated into a network is
not permitted, i.e., use of a network engineering tool is not permitted. Parameterization
may only be performed locally via SOPASET and a SiLink2 master required for configu‐
ration. When doing so, the IO-Link interface of the device must be disconnected from
the network and connected to the SiLink2 master.
7.4.2.3 Data storage
When using data storage, it must be ensured that the correct parameters of the device
have been transmitted and thereby set for the intended application when a device is
replaced (use of spare part) and after each local parameterization. It is therefore always
necessary in both cases to valid the safety-related functions in the application and to
check them for correct operation.
We therefore strongly recommend not to implement data storage to avoid unintentional
highly incorrect operation when devices are exchanged or local parameterization is
performed.
