Overview Dx35 Update to IO-Link 1.1 from serial number 20340001

From serial number 20340001 on, all Dx35 variants are delivered with IO-Link 1.1. Previously, all standard Dx35 variants had IO-Link V1.0.

The new Dx35 standard devices are compatible with the old Dx35. An exchange can therefore be carried out.

To use the sensor in the field via IO-Link, an IODD is usually used. The IODD for IO-Link V1.0 has not changed and therefore does not necessarily have to be replaced - the IODD IO-Link V1.0 was simply regenerated. Only the newly generated IODD will be available on the web page and in the IODDfinder, the "new" IODD IO-Link V1.0 can of course also be used with the old devices.

The IODD for IO-Link V1.1 is for the Dx35 after serial number 20340001 with IO-Link V1.1 (not compatible with the old devices). If you want to use the new functionalities, you must install or change to the new IODD (please note that the ISDU24 - Application Specific Tag has been shortened from 64 to 32 bytes for IO-Link V1.1 to comply with the IO-Link V1.1 standard).

On our website you will find all required IODDs (these can also be downloaded using the IODDfinder).

In addition to the new functions provided by IO-Link V1.1, our customers can choose almost freely between our device variants via "Device-Backward Compatibility". You will find a short overview of the variants in the following table:

In addition to the already known process data, our Dx35 Extended variant has the possibility of a time measuring function (timer) - previously only available in our special devices S02 and S04.

The timer function provides information on how long output Q1 is active. This can be used, for example, to measure the time for which an object is in the sensor's detection range. The timer function is available for all switching functions of output Q1.

The time measurement is started each time output Q1 changes from an inactive to an active state. The time measurement is stopped when output Q1 changes from an active to an inactive state. Once the time measurement is complete, the measured time can be read out via the process data using IO-Link.

The measured time is output in milliseconds. The accuracy of the timer is affected by the sensor's speed settings (response time, depth of the bit filter). The longest measurable time span is 65,535 milliseconds (65.5 seconds).

For the Dx35 with IO-Link 1.1 there is a new SDD with additional small functions. This SDD is already installed by default when installing SOPAS ET (from version 2020.3).

Unfortunately the match mechanism of SOPAS ET 2020.4 and older does not work properly and therefore SOPAS ET can not distinguish which SDD has to be pulled for the device. It must be checked which SDD is installed for which device.

When using SOPAS ET 2020.4 and older and a Dx35 before SN 20340001, the new SDDs (V2.x.x) must be removed manually and the old SDDs (V1.x.x) must be reinstalled or vice versa (via the "device catalog" in SOPAS ET). The table below lists which FW version was implemented at which time and which SDD should be used for the match:

*Special variants (S02/ S04)

This behaviour is fixed with SOPAS ET 2021.1.

Upload .sdv file:

When using a sensor from SN 20340001 no older *.sdv file can be loaded. (or vice versa)
First the sensor must be connected to SOPAS and a new *.sdv file must be created - (please note that in this case in SOPAS only the new SDDs are installed).
This file can then be used as usual to parameterize the new sensors.
