Description
The set EtherCAT communication cycle is displayed.
Although the communication cycle specified in "MC common settings" is in [µs] unit,
the communication cycle is displayed in [ms] unit according to the time scale
display.
Set the EtherCAT communication cycle magnification.
Range: 1 to 255
The determined sampling cycle is displayed according to the above communication
cycle magnification.
Select data measurement time. The range of measurable time varies according to
the EtherCAT communication cycle.
