Processing
● The status of the node for the node number that is specified by [S] is stored in the device that
is specified by [D1], and the execution result of the instruction is stored in [D2].
● The node status is acquired when the trigger (execution condition) turns ON.
■
Precautions for programming
● Execute this instruction after X6B (EtherNet/IP preparation done) turns ON. If the instruction
is executed before X6B turns ON, the EtherNet/IP communication preparation incomplete
error is returned as an execution result in [D2].
● Multiple EIPNDST instructions cannot be executed simultaneously. A multiple execution error
occurs. Be sure to execute this instruction after confirming the completion of the previous
execution.
