(3) How the CC-Link IE Field Network synchronous communication function
operates
At every synchronization period of the master station, A/D conversion processing is performed on the A/D
conversion enabled channels.

The figure below shows the operation timing under the following settings:
• Synchronization period of the master station: 0.88ms
• Conversion speed setting: 100μs
• Number of conversion enabled channels of the main A/D converter module: 4 channels

1) At the starting point of the synchronization period of the master station, A/D conversion starts.
2) A/D conversion takes place in the order of from CH1 to CH4 at an interval of 100μs.
At the starting point of the synchronization period of the master station, the values after A/D conversion are transferred to the
