Calculating and Verifying the Reaction Time Section 2-3
Maximum Reaction Time Formula
IMPORTANT In the SNC program, add the time for the NE1A-series Controller cycle time to
the reaction time of the safety chain when the output from a function block is
fed back to the input side of the function block.
Check the NE1A-series Controller cycle time, I/O refresh cycle time, and net-
work reaction time in the Network Configurator.
Check the NE1A-series Controller cycle time and I/O refresh time in Mode/
Cycle Time Tab of the Edit Device Parameters Window.
Item Time formula
A Local input/local output reaction time of the
NE1A-series Controller (ms) ON/OFF delay + I/O refresh cycle time
+ NE1A-series Controller cycle time
×
2 + 2.5
B Remote input/local output reaction time of the
NE1A-series Controller (ms) NE1A-series Controller cycle time + 2.5
C Local input/remote output reaction time of the
NE1A-series Controller (ms) ON/OFF delay time + I/O refresh cycle time
+ NE1A-series Controller cycle time
×
2
D Remote input/remote output reaction time of the
NE1A-series Controller (ms) NE1A-series Controller cycle time
E Input reaction time of the DST1-series I/O Termi-
nal (ms) ON/OFF delay time + 16.2
F Output reaction time of DST1-series I/O Terminal
(ms) 6.2 + Relay reaction time
(DST1-MRD08SL-1 only)
G Network reaction time (ms) Use the Network Configurator calculation result.
