Precautions for Correct Use Precautions for Correct Use
• All values of the master diagnostic and statistical information are cleared to zeros when the
power supply to the Controller is turned ON.
• The network propagation delay time is not cleared to zero when the master diagnostic and sta-
tistical information is cleared.
• Values of the network propagation delay time and transmission cycle are valid only if an Ether-
CAT slave that supports a distributed clock is assigned to the primary periodic task. If an Eth-
erCAT slave that supports a distributed clock is not assigned to the primary periodic task,
"---" is displayed.
• The items for PDO communications cycle 2 are valid only if an EtherCAT slave that supports a
distributed clock is assigned to the priority-5 periodic task. If the CPU Unit does not have a pri-
ority-5 periodic task or if an EtherCAT slave that supports a distributed clock is not assigned to
the priority-5 periodic task, "---" is displayed.
