MVP 2021 Flex727 Posted May 22, 2019 MVP 2021 Report Share Posted May 22, 2019 Not sure what you're trying to do here. All operands are retained through a power cycle (if there is a functioning battery installed). If you want the register to assume a particular value at start-up, then you use the Power-Up value to accomplish that. Looking at your program, MI 0, 1, & 9 have the power-ups checked. If you want MI 0, 1, & 9 to retain their last value, then uncheck that box. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted May 22, 2019 MVP 2021 Report Share Posted May 22, 2019 A few other items of note: 1) Do NOT place multiple logic threads in a single ladder rung, as you are doing in the Szamlalo subroutine. 2) Do NOT use Direct Contacts to call an HMI screen - use Positive Transition Contacts. 3) No need to call the Start-Up Display with SB 2 - it will be called automatically at start up. 4) No need to set or reset operands with SB 2. Use the Power-Up checkbox for MIs and SET or RESET selection for MBs. Quote Link to comment Share on other sites More sharing options...
