MVP 2023 Joe Tauser Posted December 5, 2013 MVP 2023 Report Share Posted December 5, 2013 Here's the datasheet on the encoder- http://www.wachendorff-automation.com/fileadmin/pim/WA/pdfs/en/General_technical_data_absolute_encoders_RS485.pdf It looks like it continually broadcasts data. After you untwist your brain from reading the data frame structure you should be able to interface with it using a Protocol scan block. Joe T.

DanT Posted December 5, 2013 Author Report Share Posted December 5, 2013 Thanks for the Reference; I have the V130 now reading the data properly and getting the encoder position. Anyone done a CRC-CCITT X16 + X12 +X5 +1 ( Seed 0x1021 ) CRC subroutine? There is an example of CRC calculation , but not for this Dant Quote Link to comment Share on other sites More sharing options...
