Precautions during programming• Call this instruction after X6B (EtherNet/IP preapration done) turns ON. If it is called beforeX6B turns ON, the EtherNet/IP communication preparation incomplete error is returned.• Do not execute this instruction continuously in one scan from the viewpoint of suppressingthe load.• Execute the refresh instruction after confirming that the communication of a specifiedconnection is performed normally using the cyclic communication normal node table.
