Reaction Time
Section 9-4
The cycle times read by the Network Configurator will be as follows:
Controller cycle time = 4 ms
I/O refresh cycle time = 4 ms
The cycle time of the NE1A-SCPU02 is 6 ms and the I/O refresh time is 6 ms.
The reaction time is obtained using the following equation:
Reaction time (ms) = Switch reaction time
+ NE1A-SCPU01 local input/local output reaction time
+ Actuator reaction time = Switch reaction time
+ ON/OFF delay time (NE1A-SCPU01) + 4 + 4
×
2 + 2.5
+ Actuator reaction time
=
14.5 + ON/OFF delay time (NE1A-series Controller)
+ Switch reaction time + Actuator reaction time
Note
Example 1 above shows the configuration for minimizing reaction time in the
NE1A-series Controllers. The guideline for the minimum reaction time is 15
ms for the NE1A-SCPU01(-V1) and 21 ms for the NE1A-SCPU02. The Con-
troller cannot be used when a reaction time lower than these values is
required from the Controller by the user system.

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

Network reaction time = 24 ms
Cycle time = 6 ms
