6-3 Instructions Used in EtherCAT Com-
munications
6-3-1 EtherCAT Communications Instructions
Function Instruction Description
Start EtherCAT Packet
Monitor
EC_StartMon
*1
Starts packet monitoring of the EtherCAT master
built into the NJ/NX-series CPU Unit.
Stop EtherCAT Packet
Monitor
EC_StopMon
*1
Stops packet monitoring of the EtherCAT master
built into the NJ/NX-series CPU Unit.
Save Packet Data File
EC_SaveMon
*1
Saves captured data in a file in the system of the
NJ/NX-series CPU Unit with the packet monitoring.
The packet monitoring is a function of the EtherCAT
master built into the NJ/NX-series CPU Unit.
The captured files in the system of the NJ/NX-ser-
ies CPU Unit are not retained when the power is in-
terrupted.
Copy Packet Data File to
SD Memory Card
EC_CopyMon
*1
Copies the captured data that was saved in the
system of the NJ/NX-series CPU Unit to a file on an
SD Memory Card. The captured data is previously
saved from EtherCAT master built into the NJ-ser-
ies CPU Unit into the system of the NJ/NX-series
CPU Unit.
The files saved to an SD Memory Card are retained
after the power is interrupted.
Disconnect EtherCAT Slave EC_DisconnectSlave Temporarily disconnects a slave from the EtherCAT
network for maintenance, such as replacement of
the slave.
Connect EtherCAT Slave EC_ConnectSlave Reconnects a temporarily disconnected slave to the
EtherCAT network after maintenance, such as re-
placement of the slave.
Enable/Disable EtherCAT
Slave EC_ChangeEnableSetting Enables or disables an EtherCAT slave.
Get EtherCAT Error Status GetECError Gets the status of Controller errors (partial faults or
minor faults) that occur in the EtherCAT master and
the highest-level event code for the current errors.
Reset EtherCAT Error ResetECError Resets Controller errors in the EtherCAT master.
(Execute this instruction only after eliminating the
cause of the error.)
*1. For the NJ301-
££££
CPU Units, the CPU Unit with unit version 1.10 or later and Sysmac Studio version
1.12 or higher are required to use the packet monitoring. However, for project unit version 1.40 or later, the
packet monitoring cannot be used regardless of the models of the CPU Units. If the packet monitoring can-
not be used, the
_EC_PktMonStop system-defined variable, which shows the operating status of packet
monitoring, will always be TRUE.
In addition, if you execute any EtherCAT instructions for packet monitoring (EC_StartMon, EC_StopMon,
EC_SaveMon, or EC_CopyMon) in the user program, an error that shows packet monitoring cannot be used
occurs.
Note Refer to the NJ/NX-series Instructions Reference Manual (Cat. No. W502) for details on the instructions that
are used with EtherCAT communications.
