(7) Non-group output status read
In multiple CPU systems, the scan time increases when “All CPUs can read all outputs” is selected in
the Multiple CPU settings screen of the PLC parameter dialog box.
(8) Scan time measurement
When the scan time is measured by GX Developer, the processing time shown in Table10.25 is required (
Section 6.13.3)
*1: The number of the branch instructions is a total of the following instructions, which are executed during the scan time measurement.
Pointer branch instruction : CJ, SCJ, JMP
Subroutine program call instruction: CALL(P), FCALL(P), ECALL(P), EFCALL(P), XCALL(P), RET
