BraneK Posted January 21 Report Share Posted January 21 I have a problem with the EXF-RC15, specifically its encoder input. Namely, when the power is turned off, its memory position value becomes 0. How can I overcome this problem? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted January 21 MVP 2023 Report Share Posted January 21 Look at point 2) in this topic: https://forum.unitronics.com/topic/6229-ongoing-24-topics-almost-worth-pinning/ I'm not sure if the EXF shares the issue, but it is a solution. Others can chime in if there is something better. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 22 MVP 2023 Report Share Posted January 22 The onboard high speed counter resets to 0 on power up in all Unitronics PLCs and in the RC15. If you want to retain the HSC value you must copy it continually to a buffer register in the CANbus master PLC. Check to make sure it's not = 0 before copying it to the buffer. You should be monitoring the online status of the RC15 in your master code. Here's an example of how I do it: When you see the RC15 go back online, write the value from the buffer back to the RC15. If you want to describe your application an post both your master and your RC15 programs we can have a look. Joe T. Quote Link to comment Share on other sites More sharing options...
