This section explains the procedures for and the program example of reading data from the
PCU by using the Data Read Memory area (n word, bit 13) of the PCU Control Memory area.
This section explains the procedures for reading data from the PCU with task 1 memory
operation data as an example.
Use the Special I/O Unit Memory area to read 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.
Always transfer in units of data when you read the data, and do not start or end in the middle of
data.
