4.4 Timing Chart of Output Processing

● Data is written as output relay area data to the analog output unit at the I/O refreshing timing
of the CPU unit.
● The processing of the analog output unit is not synchronized with the processing of the CPU
unit. Therefore, the analog output unit converts the latest data from the CPU unit into an
analog value and outputs it.
● The digital data conversion time of the analog output unit varies with the number of channels
and the range of use.
