Note • In the DST1-MD16SL-1 or DST1-MRD08SL-1, the time is measured
from when a safety output turns ON until the safety input turns ON
for the safety input and safety output with the same number (e.g.,
Safety Input 0 and Safety Output 0).
• In the DST1-ID12SL-1, the time is measured between two safety
inputs turning ON (e.g., Safety Input 0 and Safety Input 6).
• The operation time is stored when the time from an output turning
ON to an input turning ON is measured. The measurement, however,
continues internally until the next time the output turns ON. If the
input turns ON again before the output turns ON, the measurement
time will be updated. If an input occurs in the middle of the operating
range of reciprocating motion, like a cylinder, the measurement
value of operation (outward path) may be updated when returning
(return path).
• When an output turns ON two consecutive times before the input
turns ON, the time will be measured from the second time the output
turned ON until the time the input turned ON.
