Processing
● This instruction executes the output refresh for connections to be refreshed. "Output refresh"
means that the data is copied from the allocated devices to the send buffers.
■
Precautions for programming
● Execute this instruction after the EtherNet/IP preparation done flag (X6B) turns ON. If the
instruction is executed before the flag turns ON, the EtherNet/IP communication preparation
incomplete error occurs.
● This instruction causes a processing load. Do not execute the instruction successively in one
scan.
● Before executing this instruction, use the cyclic communication normal node table to confirm
that the communication of the specified connection is performed normally. The cyclic
