| Known issue, scheduled for new releases | Temporary workaround |
|---|---|
Codesys compatible branch (choose the right CRC tool firmware setting)
| Firmware version number | SRECS Mod Request | Changes with respect to previous version | Date of release |
|---|---|---|---|
| V4.0 (new hardware only) | 017+018 | Due to availability reasons: new MEMS chip supported, including corresponding new low-pass filter (-3dB 10Hz) for inclination (object 3014h) Object 3014h added: 0 = OFF 1 = 1st order Bessel lowpass filter 2 = 2nd order Bessel lowpass filter (default) 3 = 3rd order Bessel lowpass filter Implemented CAN object 1008h (manufacturer device name) Implemented CAN object 1009h,0 (manufacturer hardware version - euId) Implemented CAN object 1009h,1 (manufacturer hardware version - duId) Implemented CAN object 100Ah (manufacturer software version) Solved: Output freezes when switched from NMT-state ‘STOP’ to ‘OPERATIONAL’ New EDS-files are available | 2023-01-02 |
| V3.1 | 015+016 | Multiple zeroing actions could lead to an output ≠0.This has been repaired. Brandlabbeling is now supported, having a supplier-specific Vendor-ID. | 2021-06-07 |
| V3.0 | 012+013 | The angle in SRDO messages werenot updated in case ‘TPDO event time’was set to 0ms.Now the angle in SRDO-messages is independent of ‘TPDO even time’ settings.The low pass ‘Output filter’ (default off) was inaccurate in case of sensor-usage of a 1-axis 360° sensor and a movement passing the ±180°singularity point. With this firmware update the angle is accurate also in this specific situation. | 2020-12-15 |
| V2.9 | 011 | Incidentally one of the MEMS chips does not startup properly. This situation is immediately found by the µC, while comparing both MEMS chips. To prevent for hazardous situations the sensor switches to safe mode, by sending an error message only. Rebooting the device solves this issue in most situations. This modification improved the initialisation of the MEMS chips in such a way that the sensor will start up normally. | 2019-07-25 |
| 010 | SRDO-messages data was dependent on TPDO mode settings like sync-mode. This had to be split. Changes:
| Released in V2.9 | |
| 009 | Since v2.5 the sensor does not go into error-mode when operating outside it’s measuring range. But at returning to a position inside the measuring range the sensor sometimes jumped into error-mode. Now this process is improved, making the sensor significant less critical on this point and therefore the chance is having a false-alarm has decreased | Released in V2.9 | |
| V2.8 | 008 | Functionality ‘peak suppression filter’ added This functionality can be switched on by the CANopen object dictionary if required. This function makes the sensor less sensitive for vibrating situations, resulting in a significant lower chance to have a false-alarm and a non-necessary error situation. | 2018-04-03 |
| V2.7 | 007 | Not used mappings for RPDO and TPDO are now not readable as ‘0’ anymore but simply does not exist | 2017-11-07 |
| 006 | Due to difference in interpreting the CiA standard on CANopen Safety between company Codesys and DIS-sensors the CRC calculation did not match. As Codesys is market-leader the firmware was upgraded in such a way that the sensor is compatible with Codesys. Consequences:
| Released in V2.7 | |
| V2.5 | 005 | A 30° device used outside it’s measuring range (> 30° up to 90°) now gives angle data 200° (clearly a wrong angle the safety application can recognized) instead of the sensor going into error mode. | 2017-07-12 |
| 004 | Switching between RMS and PEAK value in Acceleration mode improved. Now correct values | Released in V2.5 | |
| V2.4 | 003 | Safety check on 3V3 voltage monitor improved at boot-up | 2016-08-16 |
| V2.3 | n.a. | By DEKRA released firmware, SIL2/PLd certified | 2016-08-04 |
| V2.2 | 002 | Calibration table improved for better accuracy Code readability improved | |
| 001 | Watchdog tolerances optimized to prevent for false-alarms |

005.3 | SRDO-messages data was dependent on TPDO mode settings like sync-mode. This had to be split. Changes: -SRDO-messages data now independent of TPDO mode settings -Output filter time constant maximized to redundancy_compare_time’ -TPDO_event_time’s maximized to 5000ms -‘Load default settings’ with a sensor in TPDO sync-mode will quit the TPDO sync mode -Redundancy compare time maximized to 10sec. | Released in V2.5.3 | |
