Note25
Redundant
Since the Redundant CPU cannot use low speed execution type programs, no special register
for low speed execution type programs is provided.
Note3.25
(f) When interrupt/fixed scan execution type program is executed for execution
time measurement, etc.
When an interrupt/fixed scan execution type program is executed to measure
scan time or execution time using special registers, the time of the above program
is added to the measurement time. The following values stored into the special
registers and the monitor values (measurement times) of GX Developer increase
when the above program is executed.
• Special registers
SD520, SD521 : Current scan time
SD522, SD523 : Initial scan time
SD524, SD525 : Minimum scan time
SD526, SD527 : Maximum scan time
SD528, SD529 : Current scan time for low speed execution type
SD532, SD533 : Minimum scan time for low speed execution type
SD534, SD535 : Maximum scan time for low speed execution type
SD540, SD541 : END processing time
SD542, SD543 : Constant scan wait time
SD544, SD545 : Cumulative execution time for low speed execution type
SD546, SD547 : Execution time low speed execution type
SD548, SD549 : Scan execution type program execution time
SD551, SD552 : Service interval
