Data stored Details
Continuous RUN time Continuous RUN time in TEST MODE is stored. (This register
in TEST MODE (L) stores measurement values within the range from 1 to 2147483647
(measured in increments of 1 second).) However, measurement
Continuous RUN time
starts when the operating status of the CPU module is switched
in TEST MODE (H)
from STOP to RUN. (The time is not measured while the CPU
module in the STOP state.) Note that measurement continues even
if the time limit is exceeded.
After stopping measurement, the register is cleared to 0 when the
measurement value is cleared. ( Page 541 Measuring the
continuous RUN time in TEST MODE)
SA\X (L) The number of points assigned to the SA\X device is stored in 32
bits.
SA\X (H)
SA\Y (L) The number of points assigned to the SA\Y device is stored in 32
bits.
SA\Y (H)
SA\M (L) The number of points assigned to the SA\M device is stored in 32
bits.
SA\M (H)
SA\B (L) The number of points assigned to the SA\B device is stored in 32
bits.
SA\B (H)
SA\D (L) The number of points assigned to the SA\D device is stored in 32
bits.

0: No safety cycle The number of times that cycles for which safety cycle processing
processing time was not executed were detected is stored.
