Using High-Speed Counter Instructions
14–24
Example 1
To enter the RRUN mode and have the HSC Outputs, ACC, and Interrupt
Subroutine resume their previous state, apply the following:
Ladder Rungs
Rung 2:0
No action required. (Remember that all OUT instructions are zeroed when
entering the RRUN mode. Use SET/RST instructions in place of OUT
instructions in your conditional logic requiring retention.)
