Logic programming – Function blocks
If there is a falling edge of the Dynamic cam input when the Upstroke cam input is
Low, i.e. in the Run-down phase of the press cycle, the Top output will be set to High
until a rising edge of the Upstroke cam input is detected. The Upstroke output will
remain Low for the rest of the press cycle.
If the Upstroke cam input is already High when the monitoring of the cam inputs
begins (e.g. in the first logic cycle, after resetting an error or after enabling monitoring
with
Disable monitoring input), the Upstroke output will remain Low until the first
actual transition from Low to High has been detected at the Upstroke cam input.
