4. CONFIGURATION OF EtherCAT CONNECTION
4-10
(2) Interval setting for the task
1. Double-click MainTask in the Devices window to display a window for task
configuration.
In the MainTask tab, you can set task priority, type, and interval.
2. In the task configuration window, select Cyclic for Type, and then specify 4000 (µs)
(default setting) for Interval.
If EtherCAT_Master.EtherCAT_Task is inserted under the task, you must specify
the same value as Cycle Time in the aforementioned EtherCAT_Master configuration
window.
Note: The interval of the task might be automatically changed when the value of Cycle
Time is changed in “(1) Cycle time setting for the EtherCAT master”. If you
change the cycle time setting of the EtherCAT master, check the interval setting of
the task, and reconfigure the setting if necessary.
If you want an I/O module to be controlled using a different cycle time than the
EtherCAT master, create a control task for the I/O module as an independent task from
the task where EtherCAT_Master.EtherCAT_Task is inserted.
For information about how to create a task, see “ Adding a task” in “(1) Task
configuration” in “3.1.2 Creating a PLC program”.
