Precautions for Safe Use
• If two different function modules are used together, such as when you see PCIe connected board
and EtherCAT slaves, take suitable measures in the user program and external controls to ensure
that safety is maintained in the controlled system if one of the function modules stops. The relevant
outputs will behave according to the slave or Output Unit specifications if a partial fault level error
occurs in one of the function modules.
• 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.
• Always confirm safety at the connected equipment before you perform the following operations
when the device output hold configuration is set to enable. The equipment may operate unexpected-
ly because the last status for outputs is retained.
• Changing the operating mode of the product
• When downloaded

Task Design

• If the following variables are specified for a condition expression when the execution condition is a
condition expression for a variable, event tasks may not be executed when conditions are met or
event tasks may be executed when conditions are not met:
• Structure members whose data size is 16 bits or more, except for system-defined variables for
motion control.
• Array elements whose data size is 16 bits or more.
For information on event task execution conditions, refer to the NY-series IPC Machine Controller
Industrial Panel PC / Industrial Box PC Software User's Manual (Cat. No. W558).

General Communications

• Unexpected operation may result if inappropriate data link tables are set. Even if appropriate data
link tables have been set, confirm that the controlled system will not be adversely affected before
you transfer the data link tables. The data links start automatically after the data link tables are
transferred.
• Separate the machine network segment from the office network to avoid communication failures.

EtherNet/IP Communications

• Make sure that the communications distance, number of nodes connected, and method of connec-
tion for EtherNet/IP are within specifications. Do not connect EtherNet/IP communications to Ether-
CAT or other networks. An overload may cause the network to fail or malfunction.
• All related EtherNet/IP nodes are reset when you transfer settings for the built-in EtherNet/IP port
(including IP addresses and tag data links settings). The settings can only be enabled after the re-
set. Confirm that the system will not be adversely affected by resetting nodes before you transfer the
settings.
