Features
When working with CANNY 7, it is a good practice to use the time intervals greater than 5-10 ms.
When specifying temporal values on the diagram, it is necessary to take into account the duration of the diagram execution cycle, which depends on the model of the controller, the size of the chart, controllers' operation mode, controller periphery. It may be varied from cycle to cycle within certain limits during operation. Exact execution time for each cycle is available in the register, during controller operation "Длительность программного цикла".
Time intervals in the diagram should not be specified by value less than the duration of one cycle and will be measured with an uncertainty about the duration of one cycle of a user diagram.
