3.2.1.8 Exact time setting of an output, exact time output cams (as of V4.1)
You can switch a high-speed output cam On/Off at an exact time within an execution cycle
(position control, IPO cycle) via the timeOffset parameter of the _setOutputCamState system
function.
Enter an offset of the switching edge in the configured unit (e.g. s) of the Output Cam TO in
the timeOffset parameter. The reference point of the offset is the start of the next execution
cycle of the Output Cam TO. You can read out the value of the time offset (system-dependent
execution time between the execution cycle and the output cycle) in the tOutput system
variable. The time in tOutput is the earliest possible time to switch the output cam. The
timeOffset is added to this time.
Features
● The offset must be less than the cycle time of the processing cycle clock. The offset is
● It is possible to switch on or off within one cycle.
● When this function is used, there is a dependency on the processing cycle clock and the
● The offset is valid for every output cam type. If only switched once, the unidirectional output
● The offset can only be stated if the output cam TO on the outputs is configured with a time
