The current SIL2/PLd devices with CANopen safety interface turned out to be not compatible with Codesys software running on some PLC’s. The difference is related to the CRC calculation only. The CiA standard can be interpreted in different ways. As Codesys is widely used in the market we decided to update our software to be compatible.
Apart from the CRC code, all sensor functionalities remain the same. From firmware v2.7 the new CRC calculation is implemented.
We have updated the CRC generator tool on this website to be backwards compatible. Default firmware ‘v2.7 or higher’ is selected. If required ‘v2.5 or lower’ can be selected.
All new customers will have v2.7 or higher. For existing customers we will create a customer-specific product (with firmware v2.5) to make sure you can work with your current CRC values.
If you have any questions concerning this tool, please don't hesitate to contact us.
