APPENDIX 2 OPERATION PROCESSING TIME
The operation processing time of each instruction is shown in the tables on the
following pages.
The operation processing time differs depending on values in the source and
destination. Use the values in the tables as a guide to processing time.
(1) Processing time varies depending on the I/O control mode used with any
instruction operating on inputs or ontputs.
(2) The processing time for each instruction is shown for refresh mode.
The refresh processing time after END can be calculated as follows:
Sequence program processing time =
(instruction processing time) + (END processing time) + (refresh processing time)
Obtained from the list
END processing time =
(END instruction processing time) + (T/C processing time at END)
