Corrective action
• Correct "Access target CPU setting".
• Check the communication cable status and
access target CPU status.
• Adjust the response monitoring time setting.
• Check if the control CPU of the network module
on the network route to the access target CPU
is set to QCPU (Q mode).
• Check the routing parameter settings of the
CPU(s) on the access route.
• Check the network on the access route.
• Review the Ethernet module setting of the
access target CPU.
• Correct "Access target CPU setting".
