Safety information
The following is the list of special register areas relating to the safety information.
No. Name Data stored Details Set by

CPU
SD1840 Continuous RUN time
in TEST MODE
Continuous RUN time
in TEST MODE (L)
Continuous RUN time in TEST MODE is stored. (This register
stores measurement values within the range from 1 to 2147483647
(measured in increments of 1 second).) However, measurement
starts when the operating status of the CPU module is switched
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)
