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 on page 2-3 for a timing chart for Execute, Done, Busy, and Error.
• This instruction can be used only for the NJ/NX-series and NY-series Controller EtherCAT ports.
• You cannot execute this instruction during execution of the following instructions: EC_Disconnect-
Slave, EC_ConnectSlave, EC_ChangeEnableSetting, ResetECError, RestartNXUnit, and
NX_ChangeWriteMode.
• The execution results of this instruction are not saved in non-volatile memory in the CPU Unit. There-
fore, if the power supply to the Controller is cycled after execution of this instruction or if the user pro-
gram is downloaded, the enable/disable setting of the EtherCAT slave will return to the value that
was set from the Sysmac Studio.
• You can execute a maximum of 32 of the following instructions at the same time:
EC_CoESDOWrite, EC_CoESDORead, EC_StartMon, EC_StopMon, EC_SaveMon, EC_CopyMon,
EC_DisconnectSlave, EC_ConnectSlave, EC_ChangeEnableSetting, IOL_ReadObj, and IOL_Write-
Obj.
• An error occurs in the following cases. Error will change to TRUE.
• The slave specified with NodeAdr is not part of the EtherCAT network. That is, the value of
_EC_EntrySlavTbl[i] (Network Connected Slave Table) is FALSE.
• The value of NodeAdr is outside of the valid range.
• The EC_DisconnectSlave,
RestartNXUnit, or NX_ChangeWriteMode instruction is already in execution.
• More than 32 of the following instructions were executed at the same time:
EC_CoESDOWrite, EC_CoESDORead, EC_StartMon, EC_StopMon, EC_SaveMon, EC_Copy-
Mon, EC_DisconnectSlave, EC_ConnectSlave, EC_ChangeEnableSetting, IOL_ReadObj and
IOL_WriteObj.
Version Information
A CPU Unit with unit version 1.04 or later and Sysmac Studio version 1.05 or higher are required
to use this instruction.
