Precautions for Correct Use
• Execution of this instruction is continued until processing is completed even if the value of Execute
changes to FALSE or the execution time exceeds the task period. The value of Done changes to
TRUE when processing is completed. Use this to confirm normal completion of processing.
• Refer to Using this Section (page 2-3) for a timing chart for Execute, Done, Busy, and Error.
• If you specify a Unit that is assigned to a motion control axis (data type _sAXIS_REF) for UnitProxy,
a Controller error will occur in the Motion Control Function Module. Use the ResetMCError instruction
(page 2-822) to reset the Controller error.
• For UnitProxy, specify the device variable that is assigned to the EtherCAT Coupler Unit or an NX
Unit on the EtherCAT Coupler Unit, and an NX Unit connected to the NX bus of the NX Bus Function
Module or the CPU Unit in the I/O Map of the Sysmac Studio. Refer to the Sysmac Studio Version 1
Operation Manual (Cat. No. W504-E1-07 or later) for details on assigning device variables.
• If the RestartNXUnit instruction is executed during execution of another RestartNXUnit instruction or
execution of the NX_ChangeWriteMode instruction (page 2-843), the RestartNXUnit instruction that
is executed later will be queued. Up to 192 instructions can be queued. A building error will occur if
an attempt is made to queue more than 192 instructions. The time that an instruction is queued is not
included in the timeout time.
• The value of Busy is TRUE while the instruction is queued.
• This instruction is related to NX Message Communications Errors. If too many instructions that are
related to NX Message Communications Errors are executed at the same time, an NX Message
Communications Error will occur. Refer to A-3 Instructions Related to NX Message Communications
Errors for a list of the instructions that are related to NX Message Communications Errors.
• You cannot execute this instruction during execution of the following instructions: EC_Disconnect-
Slave, EC_ConnectSlave,
NX_ChangeWriteMode. An error will occur if you attempt to execute it.
