■Operation cycle precedence method
With operation cycle precedence method, data receive, motion operation, and data send are executed in different operation
cycles. For the connected device, it takes five cycles to receive a feedback to the data sent from the connected device.
(1) Receive from the connected
station
(2) Transfer to the
high-speed receive buffer
(3) Operation processing
(4) Transfer from the
high-speed send buffer
(5) Send to the connected station
■Slave label
The I/O data which the slave device of motion syncronization stations exchanges with Motion module by cyclic communication
registers as labels and enables read/write. Refreshing slave labels are carried out in operation cycle. Refer to Help of the
engineering tool for the setting method of slave label.
Standard station
The following stations update the data.
• Programmable controller
