Conditional start node
As shown in the figure above, this is a conditionally started process. The type of the start node is a conditional node. The requirement for the process to start is that the conditional expression defined on the conditional node is satisfied.
The condition definition on the conditional start node is as shown in the figure above, where the conditional expression: days>2 clearly defines the conditions that need to be met to start the process. days is a condition variable, and the value 2 represents the condition parameter that needs to be met. When starting the process, you need to pass the value of the condition parameter days. If the value of days happens to be greater than 2, the process can start normally. If the condition is not met, the process cannot start. This method is suitable for some automatic monitoring processes, such as temperature alarms, overdue debts, overdue credit and other warning types.
