[Valid data range] 0 to 100
This item specifies the percent execution time for each PMC if the
multi-PMC function is used.
When all these parameters are 0, the standard execution time settings
listed below are used.
Table 2.4.3 (b) Standard settings of the percent execution time for
multiple PMCs
Multi-PMC configuration
PMC
having the
first
priority
PMC
having the
second
priority
PMC
having the
third
priority
First PMC only 100%
First and second PMCs 85% 15%
First and third PMCs 85% 15%
First, second, and third PMCs 75% 15% 10%
NOTE
1 If these parameters are set to too low a value, it may
be impossible to start the first level on every scan.
2 Even if you input the same program in both second
and third PMC, the scan time of both programs may
not correspond because of changing of the waiting
time by execution timing.
3 If the sum of these parameter settings exceeds 100,
the PMC alarm "ER51 PMC EXECUTION
PERCENTAGE ERROR" occurs, thus disabling all
PMC from starting.
