6 Process Data Communications and SDO Communications
 Transmission Jitter
The value of transmission jitter depends on the CPU Unit.

 Slave Input Response Time
This is the time from a slave reads input information from output devices until the slave transmits a
frame as a process data on the EtherCAT communications. This is the time required for internal pro-
cessing that is specific to each slave. Refer to the manuals for the relevant slaves.
 Slave Output Response Time
This is the time from a slave receives a frame as a process data on the EtherCAT communications
until the slave outputs the frame as output data to external output devices. This is the time required
for internal processing that is specific to each slave. Refer to the manuals for the relevant slaves.
Displaying the Transmission Delay Time for the EtherCAT Master
with the Sysmac Studio
You can use the Sysmac Studio to display the transmission delay time for the built-in EtherCAT port of
the NX-series CPU Unit. Use the following procedure to display the transmission delay time with the
Sysmac Studio.
