Operands M, D, I, and Q represent internal relay, data register, input, and output, respectively.
Breakdown of END Processing Time
The END processing time depends on the
MicroSmart
settings and system configuration. The total of execution times for
applicable conditions shown below is the actual END processing time.
Note 1:
Clock function is processed once ever y 500 ms.
Note 2:
Data link slave stations are processed in interrupt processing asynchronous to the ordinar y system processing.
I/O Delay Time
In addition to processing user program instructions and END instruction, the
MicroSmart
system processing includes
interrupt processing of various functions.
The minimum delay from a standard input to a standard output in the program below is 884.1 µs.
The I/O delay time may be increased by such factors as increased END processing time (caused by frequent interrupt pro-
cessing and larger program size) and input filter setting.
