Chapter 14 High-Speed Counter (HSC) instructions
356 Rockwell Automation Publication 2080-RM001D-EN-E - February 2015
PLS enabled results
For this example, the following events will occur.
• When the ladder logic first runs: HSCSTS.Accumulator = 1, which means
all the outputs are turned off.
• When HSCSTS.Accumulator = 250, HSC_PLS[1].HSCHPOutput is sent
through the HSCAPP.OutputMask, and energizes outputs 0 and 1.
• Sending the high preset output throught the output mask repeats as the
HSCSTS.Accumulator reaches 500, 750, and 1000, and the controller
energizes outputs 0...2, 0...3, and 0...4 respectively.
• After the full operation completes, the cycle resets and repeats from
HSCSTS.HP = 250.
