Setting method
Calculate synchronization cycles from the formula below.
Synchronization cycle = Basic period (Communication period interval setting) Magnification
Item
Basic period (Communication period interval setting)
Magnification
Set the synchronization cycle to satisfy the following condition.
1ms Synchronization cycle 1000.00ms
Set the basic period setting for master station parameters to satisfy the following conditions.
■Condition 1
Set the basic period (communication period interval setting) so that it matches the inter-module synchronous fixed scan
interval setting.
■Condition 2
Configure the setting so that the transient transmission time satisfies the setting range shown below.

1Gbps
100Mbps
*1 Use a TN HUB when communicating between Master station and FPGA module with different communication speeds.
For the setting procedure, refer to the manual for the master station being used.
Ex.
The following figure shows an example of a synchronization cycle.
