Precautions for Safe Use
• When an EtherCAT slave is disconnected from the Sysmac Studio or with an instruction,
communications will stop and control of the outputs will be lost not only for the disconnected
slave, but for all slaves connected after it.
Always confirm system safety before you disconnect an EtherCAT slave.
• If noise occurs or an EtherCAT slave is disconnected from the network, any current communi-
cations frames may be lost. If frames are lost, slave I/O data is not communicated, and
unintended operation may occur. The slave outputs behave according to the slave specifica-
tions. For details, refer to relevant manuals for each slave. If a noise countermeasure or slave
replacement is required, perform the following processing.
• Program the
_EC_InDataInvalid
(Input Data Invalid) system-defined variable as an inter-
lock condition in the user program. Refer to
6-1-3 Checking Validity of Process Data
• Set the
PDO communications timeout detection count
setting in the EtherCAT master
5-4 EtherCAT Master Parameter Settings
procedure.
