starts
Sequence program processing is stopped during the waiting time from when the END
processing of a sequence program is executed until the next scan starts.
(a) When low speed execution type program is executed
When a low speed execution type program is being executed, the execution of the
low speed execution type program is stopped for the following period.
(Constant scan) - 0.5ms
(b) When interrupt factor occurs during waiting time until next scan starts
When an interrupt factor occurs during the waiting time until the next scan starts,
either of the following programs is executed.
• Interrupt program
• Fixed scan execution type program
(c) When service processing setting is specified
The communication service processing with peripherals (such as GX Developer)
and intelligent function modules is enabled during the waiting time until next scan
starts by specifying the service processing setting in GX Developer. (
6.25.2)
Since the Basic model QCPU cannot use low speed execution type programs and fixed scan
execution type programs, it is not necessary to be conscious of this description.
Since the Redundant CPU, Universal model QCPU cannot use low speed execution type
programs, it is not necessary to be conscious of this description.
The Basic model QCPU, High Performance model QCPU, Process CPU, and Redundant CPU
do not support the service processing setting.
