10.2 Constant Scan
(1) Constant scan
In the QnACPU, the scan time varies since the processing time differs depend on the
execution status of the instructions used in the sequence program.
Constant scan is a function whereby the sequence program is repeatedly performed
while maintaining constant scan time.
When the low-speed execution type program is used, either this constant scan function or
a low-speed program execution time has to be set.
(For details, refer to the QnACPU Programming Manual (Fundamentals).)
Scan time when the constant scan is not used
Scan time when the constant scan time is set to 70ms
Scan time when the constant scan time is set to 100ms while performing multiple programs
