Example 2) Refreshing data from the receive buffer of the connection 2 of the node

Example 3) When refreshing data by the periodical interrupt processing when the

scan time is long and RPI is short. (When acquiring for each received data)

Scan time: 10 ms,

RPI (transmission interval for the EtherNet/IP cyclic communication): 500 µs

● When the scan time is longer than the setting time of RPI, the refresh cannot be executed

during the processing. In this case, describe the EIP_IN instruction in a fixed cycle execution

type PB and use interrupt processing to execute the refresh.

● If the interrupt cycle is set to the same value as that of RPI, the refresh instruction may be

executed while the receive buffer is being written, and the operation may fail. Perform the

processing after checking the refresh result.
