(4) Network Transmission Delay Time
The transmission delay on an Ethernet line is 50
μ
s or less. This delay time can be ignored.
(5) Receive Data Processing Time
This is the time required to transfer data received on the built-in EtherNet/IP port to a variable in the
Controller. Data is received during task processing. Therefore, the time required for receive data
processing is the same as the task period. If the data that is transferred is larger than the amount of
data that can be received during a single task (as set in the variable access time for the task), the
data is transferred over multiple task periods. Therefore, add (task period
×
the number of transfers)
to the time required. For details on how to determine the time required to receive data, refer to
2 Built-in EtherNet/IP Port Data Processing Time
. Data is transferred once in each task period.
Therefore, if data transfer has ended in the task period in which data is received, the start of trans-
mission for received data will be delayed by one Controller task period.
Additional Information
The total amount of data transferred increases if there are connections with multiple nodes, and
the data that is transferred may exceed the amount that can be processed in a single transfer. In
this case, the number of data transfers increases.
(6) Output ON Response Time
This is the delay time for the external output device from when the Controller specified turning ON
the output until the output is actually turned ON.
Output ON response time = Output device delay time + Controller task period
Additional Information
The I/O response time may be longer due to noise, or other events.
