Under the circumstance that the main program execution cycle is very long, when you
have to handle with special program or execute specific program every once in a while
when program is scanning in sequence control, the timing interruption is very useful. It is
not affected by PLC scan cycle and executes timing interruption subroutine every N ms.
Timing interruption is open status in default, just like other interruption subroutines, it
should be written behind the main program, starts with I40xx, ends with IRET.
There are 20 channels of timing interruptions, representation: I40**~I59**(‘**’means
interruption time; Unit is ms. E.g: I4010 means executing once the first timing
interruption per 10ms.
