Causes of Increasing Scan Time
The following shows the functions that increase the QnACPU scantime.
When using the following functions, add the values calculated in Appendix 9.1 to the
following values.
• MELSECNET/10 refresh
• MELSECNET/MINI-S3 refresh
• CC-Link auto refresh
• Sampling trace
• Monitor using GX Developer
• Local device
• Multiple program execution
• Installation/removal of memory card
• File register whose file name is the same as the program
(1) MELSECNET/10 refresh
Refresh time between QnACPU and MELSECNET/10 network module
For MELSECNET/10 refresh time, refer to the following manual.
• QnA/Q4AR MELSECNET/10 Network System Reference Manual
(2) MELSECNET/MINI-S3 refresh
Refresh time between QnACPU and MELSECNET/MINI (S3) network module
For MELSECNET/MINI (S3) refresh time, refer to the following manual.
• MELSECNET/MINI-S3 Master Module User's Manual
(3) CC-Link auto refresh
Refresh time between QnACPU and CC-Link master local module
For the auto refesh processing time of CC-Link, refer to the following manual.
• Control & Communication Link System Master/Local Module type AJ61QBT11/
A1SJ61QBT11 User's Manual
(4) Sampling trace
(a) Processing time in the case of sampling trace execution
Sampling trace data are set using GX Developer, and the processing time is
added when the sampling trace is executed.
(b) The following table shows the processing time when internal relay 50 points as a
bit device, data register 50 points as a word device are set for sampling trace
data.
