Section 11-4
I/O Refresh Cycle Time and Network Reaction Time
The network reaction time
The network reaction time of the NE1A-series Controller is used when calcu-
lating the remote I/O reaction time.
The network reaction time can be checked on the Safety Connections Tab
Page of the Edit Device Parameters Window.
Note The minimum set for the EPI is either the cycle time of the Safety Network
Controller or the cycle time of the Safety Slaves (always 6 ms), whichever is
greater. The minimum setting for the EPI will therefore be affected if the cycle
time of the Safety Network Controller is longer then 6 ms.
