This video gives basic information on Using the TMRA "Accumulating Timer"" instruction in the Do-more Designer software. It presents information that is commonly missed by users. This WILL NOT be a complete tutorial for the instruction but rather a supplement to the help file and customer experience.
This is a multi-scan instruction, because it takes multiple scans to complete, it cannot be used in either Subroutines or Interrupt Service Routines. It can used in Programs and under special circumstances can also be used in Stages inside of a Program or in Tasks. See the help topic “Instruction Set Chart” for more information. The main difference between the Accumulating Timer and a regular timer instruction is that the Accumulating Timer has a dedicated reset power rail and will maintain the time until the reset rail becomes true. If the reset rail is true it will reset the time to zero. The reset rail must be false for the timer to start timing.
