3.3.5 Conversion speed
Conversion speed indicates time from channel changing to A/D conversion completion.
Conversion speed per channel of the AJ65VBTCU-68ADV/ADI is 1ms.
Due to the data link processing time of the CC-Link system, there is a transmission
delay until the A/D conversion value is read actually.
For the data link processing time, refer to the user's manual of the master module
used.
Example) Data link processing time taken in the asynchronous mode when the master
module is the QJ61BT11 (normal value)
[Calculation expression]
