Operational Flow and Cycle Time
Section 9-2
lish the above connection has been completed until enabled I/O data is sent
and received using that connection.
(Processing time after the connection is established until enabled safety I/O
data is sent and received) =
EPI setting x 3 + NE1A-series Controller cycle time x 6
Note
After the NE1A-series Controller is initialized, it will be added to the DeviceNet
network once it has been confirmed that there are no duplicate addresses on
the DeviceNet network. This process will take approximately 2 s. This process
is not completed before starting operation if the NE1A-series Controller is set
for automatic execution at startup (i.e., automatic execution when the power
supply is turned ON). This time must also be taken into account when consid-
ering the time until DeviceNet I/O communications data becomes valid.
The cycle time of the NE1A-series Controller can be checked on the
Mode/Cycle Time 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.
