This section explains the procedures for and the program example of writing data to the PCU
by using the Data Write Memory area (n word, bit 12) of the PCU Control Memory area.
This section explains the procedures for writing data to the PCU with task 1 memory operation
data as an example.
Use the Special I/O Unit Memory area to write data with the data transfer bit.
You can determine the Special I/O Unit Memory area by the formula below:
Beginning word in Special I/O Unit Memory area (n) n = 2,000 + 10 × unit number
The memory areas that are necessary for transfer are as listed below.
Do not turn OFF the power supply or restart the PCU while you write the data. The PCU may not
operate properly if you could not transfer all data. In such a case, transfer all data again.
