Maximum Conversion Speed

3.5.1

Conversion speed per channel

3.5.2

Influence of [FROM]/[TO] instruction executions on maximum conversion speed.

Conversion speed is the period of time between channel switching and the writing of
the digital value to buffer memory.
Conversion speed per channel is 20 ms.
If more than one channel is used, the sampling time will be "(20 ms) × (number of
conversion-enabled channels)".
The maximum conversion speed indicated in 3.5.1 assumes that the [FROM]/[TO]
instruction is not executed. If the [FROM]/[TO] instruction is executed:
(1) Digital value write to the buffer memory is suspended during [FROM]/[TO]
processing until the [FROM]/[TO] processing is completed.
(2) Channel switching is suspended during [FROM]/[TO] processing until
[FROM]/[TO] processing is completed.
(3) [FROM]/[TO] processing is suspended during digital value write to the buffer
memory or channel switching until the write or channel switching process is
completed.
(4) The [FROM]/[TO] instruction should be specified to transfer more than one data
simultaneously. Processing is less influenced if the number of [FROM]/[TO]
instructions is smaller.
