Reaction Time
Section 9-4
The network reaction time will be 24 ms based on a safety connection EPI of
6 ms. The reaction time is obtained using the following equation:
Reaction time (ms) = Switch reaction time
+ Safety I/O Terminal input reaction time
+ Network reaction time
+ NE1A-SCPU01 remote input/local output reaction time
+ Actuator reaction time
= Switch reaction time
+ ON/OFF delay time (DST1-ID12SL-1) + 16.2
(= Input reaction time of DST1-ID12SL-1)
+ 24
+ 6 + 2.5
+ Actuator reaction time
=
48.7 + ON/OFF delay time (DST1-ID12SL-1)
+ Switch reaction time + Actuator reaction time

Example 3: Local input - Remote output
The following example shows calculating the reaction time from a local input
to a remote output, for the NE1A-SCPU01 node 1 and node 2 configuration
shown in the illustration.
NE1A-SCPU01 node 1 (#1) configuration:
• Program: 1 Safety Gate Monitor, 1 Reset, 1 E-STOP, 1 AND,1 External
Device Monitor
• Standard Slaves: 2 connections
• Safety Masters: None
• Safety Slave: 1 connection (EPI = 7 ms)
NE1A-SCPU01 node 2 (#2) configuration:
• Program: 1 Safety Gate Monitor, 1 Reset, 1 E-STOP, 1 AND, 1 External
Device Monitor
• Standard Slaves: 2 connections
• Safety Masters: 3 connections (EPI = 7 ms)
• Safety Slaves: None
The node 1 (#1) cycle times read by the Network Configurator will be as fol-
lows:
NE1A-SCPU01 cycle time = 6 ms
I/O refresh cycle time = 6 ms

Cycle time = 7 ms
I/O refresh cycle = 3.5 ms
