General Communications; Battery Replacement; Ethercat Communications - Omron NY Series Hardware User Manual

Precautions for Safe Use
• Press the Power Button of the product.
• Remove a USB device or SD memory card.
• Do not attempt to remove or touch the fan unit while the product is powered ON or immediately after
the power supply is turned OFF. If you attempt to replace the fan unit then, there is a risk of personal
injury due to hot or rotating parts.
• Press the power button for several seconds to force the product shutdown. Always back up files in
the planned way to prevent data loss or system file corruption.
• Do not touch any product housing when power is being supplied or immediately after the power sup-
ply is turned OFF. Doing so may result in burn injury.
• Confirm that no adverse effects will occur in the system before you attempt any of the following.
• Changing the operating mode of the Controller (including changing the setting of the Startup
Mode).
• Changing the user program or settings.
• Changing set values or present values.

General Communications

• Separate the machine network segment from the office network to avoid communication failures.

Battery Replacement

• Dispose of any Battery that has been dropped on the floor or otherwise subjected to excessive
shock. Batteries that have been subjected to shock may leak if they are used.
• UL standards require that only an experienced engineer replace the Battery. Make sure that an ex-
perienced engineer is in charge of Battery replacement.
• The Battery may leak, rupture, heat, or ignite. Never short-circuit, charge, disassemble, heat, or in-
cinerate the Battery or subject it to strong shock.

EtherCAT Communications

• Make sure that the communications distance, number of nodes connected, and method of connec-
tion for EtherCAT are within specifications. Do not connect EtherCAT communications to a standard
in-house LAN, or other net-works. An overload may cause the network to fail or malfunction.
• If noise occurs or an EtherCAT slave is disconnected from the network, any current communications
frames may be lost. If frames are lost, slave I/O data is not communicated, and unintended opera-
tion may occur. The slave outputs will behave according to the slave specifications.
• EtherCAT communications are not always established immediately after the power supply is turned
ON. Use the ECAT Network General Configuration Elements in the user program to confirm that
communications are established before attempting control operations.
• When an EtherCAT slave is disconnected or disabled, communications will stop and control of the
outputs will be lost not only for the disconnected slave, but for all slaves connected after it. Confirm
that the system will not be adversely affected before you disconnect or disable a slave.
• You cannot use standard Ethernet hubs or repeater hubs with EtherCAT communications. If you use
one of these, a major fault level error or other error may occur.
• If you need to disconnect the cable from an EtherCAT slave during operation, change to Init Status
the EtherCAT slave and all of the EtherCAT slaves that are connected after it.
