Function and Action
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.
