(b) With the extension A/D converter module connected
At every synchronization period of the master station, A/D conversion processing of the main A/D converter
module and A/D conversion processing of the extension A/D converter module take place as in the following:
Synchronization cycle

With an extension analog module connected, normal mode or trigger conversion mode involves processing time (100μs) in
the period from the completion of conversion processing of each channel to the start of conversion processing of the next
channel; however, synchronous communication mode does not involve this processing time.
