The transmission delay times for PDO communications cycle 1 and PDO communications cycle
2 are displayed in the Output Tab Page.
The transmission delay times of the EtherCAT master depend on the periodic tasks of the CPU
Units that refresh I/O with the EtherCAT slaves, as shown below.
Primary periodic task
Priority-5 periodic task
Precautions for Correct Use Precautions for Correct Use
• Sysmac Studio does not support the transmission delay time display function for the built-in
EtherCAT ports of the NJ-series CPU Units.
• You can use the Sysmac Studio to calculate and display the transmission delay times of the
EtherCAT master according to the configuration information such as the number of EtherCAT
slaves and the EtherCAT frame lengths. When you changed the EtherCAT configurations or
setup, you must perform this function again.
Version Information
Sysmac Studio version 1.13 or higher is required to use the transmission delay time display func-
tion for the EtherCAT master.
