Vyachik13 Posted July 28, 2020 Report Share Posted July 28, 2020 PLC Yazz 20-P16. I need to store 8 constants in non-volatile memory with the ability to edit them by the user. Is this possible in this model and how? Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted July 28, 2020 MVP 2021 Report Share Posted July 28, 2020 The best way is to use http://support.elmark.com.pl/unitronics/materialy/manual/u90-software.pdf it is HMI variable topic and some other U90 ladder command.

Vyachik13 Posted July 29, 2020 Author Report Share Posted July 29, 2020 Thank. This document says that the first 16 MB and MI for the M90 and M91 devices are non-volatile. Question: Does this provision apply to Jazz series devices? Quote Link to comment Share on other sites More sharing options...

If SB 8 is on the internal battery is low. Joe T. Quote Link to comment Share on other sites More sharing options...
