Hardware Interrupt on Trigger “Reached End of Scan Cycle”
By parameterizing the hardware interrupt a the end of the scan cycle, you have the
option of synchronizing a process with the scan cycle of the analog input module.
A scan cycle includes the conversion of the measured values of all enabled
channels of the analog input module. The module processes the channels one
after the other. After all the measured values have been converted, the module of
the CPU reports by means of an interrupt that there are new measured values on
all channels.
You can use the interrupt to load the currently converted analog values.
