 Processing
• This instruction refreshes data only when new data is received for the target connection of
the refresh.
• (Input refresh: Data is copied to the device allocated from the receive buffer.)
 Precautions during programming
• Call this instruction after X6B (EtherNet/IP preapration done) turns ON. If it is called before
X6B turns ON, the EtherNet/IP communication preparation incomplete error is returned.
• Do not execute this instruction continuously in one scan from the viewpoint of suppressing
the load.
• Execute the refresh instruction after confirming that the communication of a specified
connection is performed normally using the cyclic communication normal node table.
