(4) When an extension A/D converter module is connected to a main D/A
converter module
When an extension A/D converter module is connected to a main D/A converter module, the conversion speed is
fixed to 100μs for the main D/A converter module and the extension A/D converter module. In addition, between
the conversion processing of each channel, processing time (100μs) is generated.
Therefore, the sampling period of the extension A/D converter module is given by the following:
Sampling period = (Conversion speed (100μs) + Processing time (100μs)) × Number of conversion enabled
channels
Ex.
Assuming that the number of conversion enabled channels is 4 for both the main D/A converter module
and the extension A/D converter module
Sampling period of the main D/A converter module = (100μs + 100μs) × 4 = 800μs
Sampling period of the extension A/D converter module = (100μs + 100μs) × 4 = 800μs
